Over 5 years have passed since the Great East Japan Earthquake of March 11, 2011. In many tsunami-affected municipalities, the reconstruction of infrastructure such as roads, ports, seawalls, or the preparation of tsunami-safe, raised building land is proceeding relatively well, following municipal reconstruction plans. This is due to a lack of communication and community involvement in reconstruction plans. In such situation, it would be effective to set up a community development council, which is a special form of public private partnership between the local government, residents, and landowners. The council would facilitate the communication between all the involved stakeholders and take care of the management of shared facilities such as shops or housing. At the Naiwan area of Kesennuma city, in Miyagi prefecture, the planning of invasive, large-scale coastal protections was proceeding without consensus being formed among the affected citizens of the area. Most of the public discourses materialized around the reconstruction of the infrastructure such as the seawall that would protect the Naiwan area, but debates about the overall recovery program with the reconstruction of buildings and community facilities didn't proceed accordingly. In order to reach a consensus, the members of the municipal reconstruction council enlisted the support of Waseda University, to which also the author belongs. The facilitation of the reconstruction planning process was promoted in the form of a participatory action research. This research was conducted in order to document and analyze the importance of establishment of community development corporations promoted in the form of a participatory action research. Our team supported the council with reaching an agreement for the overall recovery program and to prepare the field for individual reconstruction projects. The team facilitated this process by organizing discussion rounds and by using different physical as well as digital models of the area. In many disaster-affected areas of Tohoku the reconstruction of private residences and shops is still lagging behind and therefore a careful analysis of Naiwan's widely recognized and groundbreaking recovery planning process is of great importance. At first, we will explore and analyze the main issues of the Naiwan area, which had to be resolved through the reconstruction process. At the Naiwan area, a reconstruction planning council was established by the local citizens, in order to raise resistance against and develop alternatives to controversial government plans for the construction of large-scale and invasive coastal protections. However, beyond the issue of the hotly debated seawall, the discussion about the detailed local reconstruction program including the rebuilding of residences and shops as well as the establishment of a Machizukuri enterprise for the implementation of plans, didn't take place in the council. Next, in order to facilitate a wider discussion process and reanimate the stagnant reconstruction planning process, we designed a process to reach an agreement between all the stakeholder by soliciting and discussing creative ideas from the subcommittee in Management Conference, and then explaining and discussing the in wider plenary sessions. At the Management Conference, we supported the consensus formation from the broader development of plan to the development of the respective private project plans by utilizing workshops and various innovative communication and visualization formats by PDCA, plan-do-check-act cycle. Based on these results, we evaluated the result of the above reconstruction planning process, from the establishment of council to the development of recommendations and plans, as well as the establishment of community development corporations as business.
