Impact of Chronic Organ Disorder Staging on Hospitalization Risk in Elderly Patients With Multimorbidity: A Retrospective Cohort Study.

Introduction Multimorbidity, defined as the coexistence of two or more chronic conditions, is increasingly prevalent in the aging population and is linked to adverse health outcomes, including hospitalization. Chronic organ disorder (COD) is a proposed framework in Japan to assess multimorbidity by categorizing organ dysfunction stages. This study investigates the association between COD stages and hospitalization rates in elderly patients with multimorbidity. Method A retrospective cohort study was conducted at the Internal Medicine Department of Unnan Municipal Hospital. Patients aged 18 and older with multimorbidity, defined as having two or more chronic diseases, who visited the clinic from April to September 2022 were included. COD stages were classified from A to E, representing increasing severity. Logistic regression analysis was used to evaluate hospitalization-related factors, including age, BMI, serum albumin, and COD stages. Results Among 568 patients, 66 (11.6%) were hospitalized. Hospitalized patients were older (75.5 vs. 58.8 years, p < 0.001), had lower BMI (20.65 vs. 22.21 kg/m², p = 0.003), and lower serum albumin levels (3.70 vs. 3.96 g/dL, p < 0.001). Advanced COD (Stage B or above) was associated with an increased risk of hospitalization (OR: 1.86, 95% CI: 1.01-3.45, p = 0.048). Age ≥75 years (OR: 2.93, 95% CI: 1.55-5.54, p < 0.001) and low BMI were also significant predictors. Conclusion This study demonstrates that advanced COD stages, age, and low BMI are significant predictors of hospitalization in patients with multimorbidity. Comprehensive COD assessment aids in identifying high-risk patients and potentially guides preventive interventions to reduce hospital admissions.

Cultural Adaptation of the Actionable Health App Evaluation in Japan: Protocol for a Web-Based Modified Delphi Expert Consensus Study

Background With an increase in both the number of mental health disorders people are experiencing and the difficulty in accessing mental health care, the demand for accessible mental health care services has increased. The use of mobile devices has allowed people to receive care in their daily lives without restrictions on time or location. However, the majority of publicly available mobile health apps are not evidence-based, and the top-rated apps are not always safe or user-friendly and may not offer clinically beneficial results. Objective This study aims to create a cultural adaptation of the American Psychiatric Association’s comprehensive app evaluation framework in Japan using a web-based modified Delphi expert consensus. Methods A web-based modified Delphi study includes developing the Japanese version of the comprehensive app evaluation framework and 3 Delphi rounds. In the first round, our working group sends a questionnaire to the panelists, who then complete it. In the second and third rounds, the working group sends a questionnaire and a summary of the panelists’ answers based on each of the previous rounds. The panelists answer the questionnaires based on this summary. The summarization procedure is automated to help reduce the biases that can be generated when panelists’ answers are summarized and when the panelists receive them. The working group sends only the result of the summarization with the next round’s questionnaire. All interactions between the working group and the panelists will be conducted on Qualtrics (Qualtrics Japan LLC), a questionnaire platform. To culturally validate the comprehensive mental health app evaluation framework, participants from the following three categories will be recruited in Japan: (1) researchers, (2) practitioners, and (3) app developers. Results This study received funding from a crowdfunding campaign in Japan (April 2023). The Delphi study began in January 2023 and will be completed in December 2023. We had already completed the translation of the 105 original app evaluation item questions by December 2022. Conclusions While the need for treatment using mental health apps is increasing, no framework that can be used to develop a centralized database for health apps is available or accessible, and no consensus has been reached among stakeholders in Japan about an appropriate framework. The results of the web-based modified Delphi method presented in this paper may provide direction for the development and use of mental health apps in the future among the relevant stakeholders. Furthermore, this study will enhance recognition of the framework among researchers, clinicians, mental health app developers, and users, in addition to devising new instruments to help users or practitioners efficiently choose the right app for their situations.

Airport detection in remote sensing real-open world using deep learning

Remote sensing real-open world of large-scare areas brings a high false alarm rate to object detection because of highly complex backgrounds. In this study, we constructed a two-stage extraction framework candidate region extraction (CRE)–multi-core binary analysis (MCBA) (CRE-MCBA) to improve the correct detection rate (DR) and reduce the error DR for airport extraction in large-scale remote sensing real-open areas. First, global sample labeling and large-scale runway CRE were conducted. Open-sourced data were applied to match the detection results spatially, and the MCBA was built for the issue of unbalanced positive and negative samples to mine potential airports. The minimum penalty term δ was also introduced into focal loss to improve detection ability in a remote sensing real-open world area. In the 219,041 km 2 study area at the Yangtze River Delta in China, the detection and error reduction rates were 100% and 97.3%, respectively. A total of 37 airports with prominent runway characteristics were detected, with 9 newly added airports. We also test the CRE-MCBA framework in Japan, Korean Peninsula, and Madhya Pradesh of India. Compared with other detection methods, ours has more robust regional adaptability and generalization ability and realizes the practical mining of potential objects.

Normalized injustices in the national energy discourse: A critical analysis of the energy policy framework in Japan through the three tenets of energy justice

This review provides a new perspective on issues about Japan's energy policy, emphasizing inherent justice failings in the country's energy policy framework—energy security, economic efficiency, environment, and safety (3E + S). To do so, we integrated a conceptual framework of energy justice synthesized from a review of the energy justice literature into a review of Japan's energy policy discourses, particularly the positioning of the 3E + S framework and its institutional basis in relation to the changes after the Fukushima nuclear disaster. The analysis revealed that besides a few fruitless attempts to integrate aspects of justice into energy policymaking in the immediate aftermath of Fukushima, the energy policy framework enforces the energy security paradigm of the post-oil shock period and carries inherent justice failings. This points to the normalization effect of injustices through institutionalization under the influence of the nuclear power industry. The analysis indicates a need to rethink the current 3E + S framework to integrate a framework of energy justice that addresses the inherent justice failings into energy policy decision-making beyond the energy security and economic growth paradigm, increasingly urgent needs as Japan works toward achieving its net-zero CO2 commitment and its overall climate-change alleviation goals by 2050.

Clinical Training of Pharmacists after Licensure and Career Paths in Medical Institutions

In order to provide safe and effective pharmaceutical care to patients and their family members in clinical practice, pharmacists should receive appropriate clinical training after obtaining their license, as is standard in other medical professions. At present, there is no national framework in Japan for the early clinical training of pharmacists after licensure. However, pharmacy residency programs have been autonomously developed and implemented at some university hospitals and other medical institutions. This article describes the current status of clinical training of pharmacists after licensure in Japan. Furthermore, the standards for pharmacy residency programs, the outline of a core program for clinical training, and the career paths of hospital pharmacists after training are discussed.

Energy justice in Japan’s energy transition: pillars of just 2050 carbon neutrality

Abstract Energy justice is a topic that is currently being explored by energy law experts around the world and used across several academic fields in energy research. However, we note that this concept is quite novel in Japan (there have been no substantial publications published in either English or Japanese) and could be expanded. This is especially important in light of Japan’s aspirations to achieve carbon neutrality by 2050 and implement a just energy transition. In this context, the article’s goal is to present the energy justice theory in a legal (energy law) and policy (climate-energy policy) framework in Japan. The article discusses the five basic types of justice, referring to Japanese energy legislation and climate-energy policy as examples. The analysis includes an assessment of the carbon neutrality pillars (seen through the prism of energy justice theory), aimed at supporting Japan in meeting its climate targets, and directions related to the use of renewable, conventional and nuclear energy sources requiring examination in terms of energy justice (due to failures of energy policy, such as lack of stakeholder recognition, local conflicts, NIMBY, etc.). Furthermore, the article demonstrates the improvements required in the legal and policy frameworks in Japan to make the application of human rights and the Sustainable Development Goals across the energy life-cycle effective. This will also include an examination of potential legal and organisational changes, and new structures and appointments in the Japanese administration.

CSCL and Industrial Chemical Management Framework in Japan

Despite Japan’s presence in the global economy, its industrial chemical regulations were less accessible than other economies’ chemical regulation frameworks, such as the United States’ Toxic Substances Control Act (TSCA) and Europe’s Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH), due to the limited information in English. Since the Japanese government considered chemical regulations as domestic issues, it did not prioritize disseminating information to overseas stakeholders. This Case Study outlines Japan’s industrial chemical regulation framework and highlights the Chemical Substance Control Law (CSCL) by elaborating on its development history and amendments. The author was involved in CSCL implementation for more than 14 years.

The advocacy coalition framework in Japan: Contributions to policy process studies and the challenges involved

AbstractThe advocacy coalition framework (ACF), a unified framework for understanding the policy process, has been applied in various countries and regions; however, there are few contributions from Japan, despite seemingly favorable conditions for applying it. An exploration of what hinders ACF applications in Japan is worthwhile for developing the ACF as a framework for comparative policy process studies across various social and political settings. Therefore, this study aims to systematically review previous Japanese ACF studies. Our review found that Japanese ACF studies are fewer in number, have less coverage of policy fields, and have less methodological diversity and transparency than international trends. While most of the Japanese ACF studies supported the basic hypotheses of the ACF, we found a need to refine some hypotheses and research methods of the ACF studies. We also discuss the background factors in the inactivity of ACF studies in Japan and suggest solutions for it.

A legislative framework for environmental flow implementation: 30‐years operation in Japan

AbstractThe Japanese environmental flow (e‐flow) concept and framework are outlined in the current study. We first review the natural and historical background related to the establishment and implementation of the e‐flow framework in Japan. We then summarize the national guidelines used to assess e‐flows. Finally, we discuss a river for which the guidelines have been applied to set e‐flow requirements. It is legally mandated that flows be established to maintain the riverine environments of class A rivers managed by the national government. These correspond to e‐flows, which are referred to as maintenance flows in Japan. A Guideline established in 1997 provides detailed instructions on how to assess e‐flows, and the e‐flow framework has been implemented for 100 class A rivers according to the guidelines. E‐flow objectives in Japan are intended to benefit ecosystems through the protection of river habitats and fisheries and the protection and maintenance of water quality, groundwater levels, riverine scenery, and navigable waterways. E‐flow objectives also address cultural and social needs, such as the prevention of salt damage and estuary clogging, and the protection of wooden infrastructure management facilities. Although Japanese rivers are characterized by large fluctuations and sudden peaks in flow, there has been little discussion about e‐flow evaluation methods that take flow variability into consideration. This is because dams on Japanese river basins control only a small percentage of total runoff volume. This is one reason why the guidelines for setting e‐flows focus only on the minimum flows required to prevent extreme low‐flow conditions.

Service Delivery Reforms for Asian Ageing Societies: A Cross-Country Study Between Japan, South Korea, China, Thailand, Indonesia, and the Philippines.

Introduction:Japan’s health policies to address the most advanced-aged society have been the target of focus in Asia, but no studies have investigated this issue using tools for cross-country comparisons.Theory and methods:A cross-country study design was used to compare healthcare reform policies with a framework in Japan, Korea, Thailand, China, Indonesia, and the Philippines. Data were collected via document reviews and key informant interviews.Results:Three distinctions were identified. First, all countries except for the Philippines have policy decisions regarding reforms for the existing service delivery systems for healthcare, long-term care and welfare. Second, the most extensive service delivery reform is currently being implemented in Japan, whose system is shifting to primary health care. Third, the direction of the transformation of service delivery system is different between Thailand and China despite a similar level of ageing society. China has made progress on facility-based care integration between health and social care, whereas Thailand is focusing on home-based care.Conclusions and discussion:Doctor and hospital-based healthcare delivery system requires more drastic reform for an aged society. This fact implies that strengthening primary health care is not only useful for current health issues but also an investment for the aged society near future in low- and middle-income countries.

Legal Framework of Urban Underground Space in China

The booming of three-dimensional (3D) land use brings a change of the connotation of land rights, which will expand “flat” 2D land legislation with 3D land legislation. The legal issues of urban underground space for 3D objects in large cities around the world have been attracting more and more attention. A supportive legal framework is crucial for underground space utilization in a country. This paper analyzes the present 173 representative laws and regulations of urban underground space utilization and management of China from 1998 to 2018, and attempts to interpret the current laws and regulations of underground space from four aspects; by quantity, spatial distribution, legislative force and content. The result shows that poor legal framework of urban underground space in China, including low-level of legislative force, disunity of local legislation standard and absence of special statutes and regulations, are the main reasons causing ownership disputation, registration chaos, as well as no unanimous judicial practice. To address these issues, the paper refers to a case study for underground space legal framework in Japan and aims to form a set of top-down unified legal framework, including basic law, special statutes and regulations, as well as supplementary policies and documents of urban underground space, and proposes that the underground space planning should be incorporated as one essential portion of the master planning in China. By studying the legal system of underground space in Japan and China, this study may offer better insight for those conducting UUS legal framework research as well as serve as reference for countries with similar legal issues.

Osvrt na povrede konkurencije u japanskom pravu

Author in this paper analyses competition violations under the Antimonopoly Act in Japan. Legal definition of competition violations is presented in the first chapter of paper as follows: private monopolization, unreasonable restraint of trade, and unfair trade practices. The second part of the paper focuses on the procedural course of identifying competition violations and the role played by the Japanese Fair Trade Commission in this process. Finally, the importance of the leniency program is emphasized as one of the most effective means of preventing anticompetitive behaviours of market participants. Throughout the paper, the author points out that there are some differences between competition legal framework in Japan and the European Union. The inspiration for writing this paper is the author's desire to share his own experiences and knowledge, gained during a three-week study visit to Japan in direct work with employees of the JFTC and professors in the field of competition law, in order to acquaint the expert public in the Republic of Serbia with Japanese competition law. During the research, the author used sources from the official site of the JFTC, as well as other relevant articles on the Internet.

Development of an interprofessional competency framework for collaborative practice in Japan

ABSTRACTRapid aging of the population necessitates improved collaboration among healthcare professionals. Unfortunately, interprofessional collaboration has yet to be implemented effectively in Japan. Therefore, we aimed to develop an interprofessional competency framework for Japanese healthcare professionals. The project was conducted as a four-step process, starting with initial categorization of potential competency domains,, followed by guiding principle and prototype development, feedback on the prototype, and final consensus. First, authors (JH and MO) collected opinions about competency in interprofessional collaboration at two academic meetings of the Japan Association for Interprofessional Education (JAIPE) and then analyzed the data thematically. Second, a project team consisting of JAIPE and University representatives extracted the domains and statements as prototype 1. Third, seven representatives from professional organizations joined the project team and developed prototype 2. We then called for feedback on the revised prototype 2 at both an open symposium and via public comments. Following revision of prototype 2, a new project team including 20 university, professional organization and health practitioner representatives finally discussed prototype 3, developed the final draft and reached a consensus. In analysis after collecting the data, we extracted 11 themes. We developed four key principles which applied to six domains as prototype 1–3. Finally, our competency framework included two core domains of “Patient-/client-/family-/community-centered” and “Interprofessional communication”, and four peripheral domains of “Role contribution”, “Facilitation of relationships”, “Reflection” and “Understanding of others”. We developed an interprofessional competency framework in Japan which consists of two core and four peripheral domains. The interprofessional competency framework is likely to affect the understanding of “high-context” and “relationalism” in Japanese healthcare. We hope that our interprofessional competency framework will encourage the systematic implementation of interprofessional education and collaboration in Japan.

Legal Research on the Abuse of Patent Litigation and the Defensive Measures for the Japanese and Taiwanese IT Industry

Abstract The patent assertion entity (PAE) which known as “the world, particularly severe impact in the US Specifically, in 2013, the report entitled “Patent Assertion and US Innovation” issued by the National Economic Council and Council of Economic Advisers of the US clearly reflected the significant harm of patent assertion toward the economic development of the country. Moreover, the Congress of the United States planned to reconsider the Innovation Act for combating PAEs at the beginning of May. The ongoing discussion in the Congress implies that analyzing the 2015 proposed Innovation Act is important for finding appropriate solutions to solve the remaining problem regarding the abuse of patent litigation in the US, specifically, Patent Trolling activity costs the US economy billions of dollars per year. The IT industry is the main target of patent trollers, briefly, due to the standard for considering the eligibility criteria for a software patent is still weak. Admittedly, many legal scholars believe that the proposed bill will be the significant tool for solving the abuse of patent litigation. For this reason, this research will analyze the major provisions in the proposed bill. Additionally, related cases in the US also will be addressed in this research, for instance, the case between Octane Fitness, LLC and ICON Health &amp; Fitness, Inc. which will be discussed herein. This paper will define the concept of the patent assertion or patent troll and examine the relationship with IT industry. The paper will then clarify the significant role of the Innovation Act 2015 in the patent assertion. Further, this thesis will compare the major provisions of the Innovation Bill 2015 by separating into five main issues with the regulatory framework in Japan and Taiwan, study the rules which were laid down in the landmark cases to understand the court interpretation and propose the suggestion for selected countries to address aforementioned problem. In other words, an analysis of the Patent Assertion Entities situation in Japan and Taiwan will be conducted focusing on the regulatory framework for preventing patent troll and its activities because Japanese and Taiwanese IT Industry normally be targeted by foreign patent trollers. This situation led to the defensive measures issued by the Japanese and Taiwanese government which will be addressed in this paper. A comparative study of the Innovation bill and the domestic laws of Taiwan, Japan, and related factors will be analyzed herein.

Special Issue on Infrastructure Maintenance, Renovation and Management

Building a sustainable economy is one of Japan’s most pressing issues today, and the only path forward is through innovations in science and technology. Under the leadership of the Prime Minister and the Minister of State for Science and Technology Policy, the Council for Science, Technology and Innovation (CSTI) has taken a high-altitude look across Japan’s ministries, proposing a comprehensive policy for science, technology, and innovation. As part of this policy, the SIP program has been designed as a fast-track research and development project, encompassing basic research, practical adoption, and commercialization. This nationally-sponsored program for science and technology innovation crosses the traditional framework of Japan’s ministries and agencies, as well as the traditional boundaries of scientific disciplines. The SIP has identified 11 issues from the field of energy, next-generation infrastructure and regional resources in order to address social issues, revitalize the Japanese economy, and bolstering Japan’s industrial posture in the world. As one of eleven themes, a new R&amp;D program named “Infrastructure maintenance, renovation and management” was launched in 2014. The new R&amp;D program is a 5-years program covering various subjects with key technologies such as non-destructive testing, monitoring, robotics, long-term performance prediction, development of high-quality durable material for repair and replacement, and infrastructure management using advanced information and communication technologies (ICT). The program consists of 60 research projects involving universities, research institutes and industries. This initiative is expected to prevent further accidents and setting an example for efficient infrastructure maintenance by reducing the burden of maintenance works and costs. This special issue aims at introducing some of the activities of the ongoing SIP “Infrastructure maintenance, renovation and management.” We are delighted to see publication of twenty-one technical papers/reports on this theme. We hope that readers would find this special issue interesting and valuable; and we greatly appreciate the authors for their contributions.

Colonial Encounter and Inculturation

Tenrikyo is a Japanese new religious movement that, like others, has tried to expand overseas and which has achieved this expansion most successfully in Taiwan. The article will focus on Tenrikyo in Taiwan and ask why it has done comparatively well. The Tenrikyo religious community has endured, and continues to survive, both a colonial and post-colonial environment in Taiwan. I contextualize Tenrikyo’s development within the framework of Japan’s relations with Taiwan, arguing that the issue of Tenrikyo’s missionary activities in Taiwan is not only inextricably linked to the historical development of Japanese religion itself, but also to colonialism. In addition, I argue that certain aspects of Tenrikyo’s doctrine, idioms and practice are compatible with the religious system in Taiwan, thus enabling Tenrikyo to make inroads into local religion through the process of inculturation. Based on my ethnography, I show that practicing Tenrikyo’s rituals such as Mikagura-uta played a prominent part in the propagation of Tenrikyo in Taiwan.

Examining the Relationship between Leader-Member Exchange and Subordinate Outcomes: The Mediating Effects of Role Clarity: A Study from an Arabic Cultural Context

IntroductionThe relationship that a leader has with individual followers is an important factor in the leadership process. The quality of the supervisor-subordinate exchange relationship is vital to employee attitudes and behaviors (Schyns and Day, 2010; Schyns, Maslyn, and Veldhoven, 2012). The quality of the relationship between supervisors and subordinates has often been studied via LMX theory (e.g. Carson and Carson, 2002; Erdogan and Enders, 2007; Harris, Harris, and Eplion, 2007; Janssen and Van Yperen, 2004; Lee, 2005; Liang, Ling, and Hsieh, 2007; Levy and Hall, 2006; Mardanov, Sterrett, and Baker, 2007) LMX can be defined as the interpersonal relationship between a subordinate and his or her leader (Lee, 2000). Previous research has shown that successful interaction between leaders and their followers are central to the overall functioning of a company (Graen and Uhl-Bien, 1995). Similarly, previous studies also reported that high quality LMX have been found to have a large impact on employee performance, organizational commitment, and job satisfaction (e.g. Gerstner and Day, 1997; Graen and Uhl-Bien, 1995; Vatanen, 2003).Previous studies tested the theory of LMX and reported inconsistent results. For example, Dunegan, Uhl-Bien; and Duchon (2002) reported that the relationship between LMX and turnover has been weak and unstable. Similarly, studies investigated the relationship between LMX and subordinate performance have not produced consistent positive results (Dunegan, UhlBien; and Duchon, 2002). This study focuses on these inconsistencies. The study objective is to help clarify the LMX-work outcomes relationship by assessing how that relationship may be influenced by some potential mediators. Specifically, the study will examine role clarity to determine if it mediates the relationship between LMX and job satisfactions, organizational commitment, and turnover intentions.In addition, it should be noted that LMX theory has mainly been applied in a Western setting (Vatanen, 2003). A few studies have examined the relationship between LMX and work outcomes in a non- Western culture. For example, Wakabayashi and Graen (1984) examined the LMX framework in Japan; Hui, Law, and Chen (1999), who tested LMX theory in China; and finally Pillai, Scandura, and Williams (1999) who applied LMX theory in India, Jordan and Saudi Arabia. This use of LMX theory in a non- Western context provides some support for the assumption that LMX theory is useful for the study of leader-follower relations within the UAE. Demonstration of the applicability of the LMX framework to an intercultural UAE context would increase the external validity of the framework as well as enable its expansion (Vatanen, 2003).Based on the above, this study attempts to narrow this gap by empirically testing the degree to which high quality LMX develops higher job satisfaction and organizational commitment and lower turnover intentions in the UAE. In addition, this study is to examine the mediating role of role clarity for the relationship between LMX and work outcomes for the first time in the Middle Eastern context. The present study extends earlier research by attempting to address the generalizability of a Western theoretical framework of LMX in a non- Western context of the UAE.Leader-Member Exchange (LMX) TheoryTraditional leadership theories focused on explaining leadership as a function of the personal characteristics of the leader, the features of the situation, or an interaction between the leader and the group (Gerstner and Day, 1997; Lee, 2000). These previous theories of leadership had often made an assumption that leaders treat all subordinates the same and that is called Average Leadership Style (ALS) (e.g. Harris, 2004). Dansereau, Graen, and Haga (1975) proposed that leader-member relationships are heterogeneous. The relationship between a leader and a member contained within a work unit are different, and that each leader-member relationship is a unique interpersonal relationship within an organizational structure (Harris, 2004). …

Regulatory and institutional framework in Japan against the background of Fukushima

On 11 March 2011, Japan endured one of the worst natural disasters in its history when a massive earthquake hit the Pacific coast of the country, followed by a tsunami, which led to a terrible loss of lives. It also led to serious accidents at the Fukushima Daiichi nuclear power units which the Japanese authorities classified at level 7 on the International Nuclear

Open Regionalism and Regional Governance: A Revival of Open Regionalism and Japan’s Perspectives on East Asia Summit

This paper explores Japan’s perspectives on the East Asia Summit, and its attempts to revive open regionalism as a conjunction of globalism and regionalism. Japan’s approach to regionalism has been centred on what we call ‘open regionalism’. As this paper presumes, an open regionalism is symbolised and represented in Japan’s unique approach to regional governance that attempts to bridge the tension between globalism and regionalism. The aim of this paper is, therefore, to conceptualise the complex interplay between open regionalism and regional governance as initiated by Japan. By investigating Japan’s political discourses on domestic and foreign policies, this paper attempts to describe Japan’s open regionalism towards the Summit and towards the East Asian Community as a revival of open regionalism, and to investigate its impact on regional governance. The chief hypothesis is that Japan’s perspectives on the East Asia Summit can be seen as a resurgence of open regionalism discourses, and that discourses have been Japan’s typical approach to regional governance. For the purposes of examination, this paper assesses, with reference to Peter Katzenstein’s porous regionalism and T. J. Pempel’s geopsychology, a framework of Japan’s open regionalism in relation to its regional governance and contemporary Asian regionalism. The paper is organised into five parts: the first part theoretically and systematically reviews Japan’s approach to open regionalism and regional governance; the second part briefly overviews the East Asia Summit; the third and fourth parts examine the domestic political context, centred on Japan’s EPA policies, and then Japan’s foreign policy discourses toward the East Asia Summit; finally, the fifth part then evaluates a resurgence of open regionalism and Japan’s perspective on the East Asia Summit and its theoretical implications for regional governance.
