Abstract: * This study investigates expatriate adaptation using a sample of Japanese expatriates in the US. For a comprehensive understanding, home managers in Japan and host managers in the US were also used. * This study is unique in that it examines expatriate adaptation through an analysis of the change of a fit between 12 learning skills and the skills demands. * The degree of expatriate adaptation increased in accordance with the length of the current overseas assignment tenure in the host country, along with an increase in job satisfaction. Keywords: Expatriate adaptation * Experiential learning theory * Learning skills * Skills demands * Job satisfaction * Japan-US business Introduction In the past few decades, many researchers and theorists have focused on the study of expatriate adaptation in the domain of international management. Their topics of study comprise, among others, the adjustment process (Black et al. 1991; Aycan 1997), acculturation (Mendenhall and Oddou 1985), the paradox of adjustment (Brewster 1993), expatriate well-being at work (Nicholson and Imaizumi 1993), expatriate adjustment and satisfaction (Torbiorn 1982), expatriate experience and adjustment (Thomas 1998; Selmer 2002; Takeuchi et al. 2005), and so forth. Although a wide range of views have been presented in the studies on expatriate adaptation, the prime focus of most of these studies is on sociopsychological and welfare concern or psychological well-being that reflects the concept of expatriate adjustment (Kamoche 1997; Wong 2001). More specifically, Haslberger (2005a) pointed out that much of the cross-cultural adaptation research in the management literature has been associated with the three types of expatriate adjustments initially proposed by Black (1988): General, work, and interaction adjustments. Since these types of adjustments refer to expatriates' psychological comfort in situations (Black 1988, 1990; Black and Gregersen 1991; Takeuchi et al. 2002), they appear to converge into an emotional aspect of the expatriates. Kamoche (1997) argued that this trend may result in a misleading impression because it appears as if all the functions of expatriate management control only the welfare and social needs of the expatriates for their overseas adjustment. Cross-cultural adaptation, however, is a multifaceted phenomenon (Berry 1997) and will be discussed later; it includes affective, cognitive, and behavioral components in its theoretical foundation (Kim 1988, 1995). In keeping with this perspective, Ashford and Taylor (1990) discussed from the viewpoint of adaptation to work transition that the adaptation processes are associated with these three constructs. Therefore, expatriate adaptation may be thought to constitute the following three facets: Emotion, cognition, and behavior (see Haslberger 2005a, b). In this regard, the scope of the study on expatriate adaptation needs to be developed from the perspective of cognitive and behavioral concern, rather than only stressing on the emotional aspects, as is the dominant trend in the literature on expatriate management. For this reason, the present study particularly focuses on a behavioral aspect of expatriate adaptation by examining expatriate skills in relation to the demands for these skills. In addition, the study aims to investigate expatriate adaptation through an analysis of expatriate job satisfaction as its emotional aspect. Literature Review Cross-Cultural Adaptation Cross-cultural adaptation has been studied and discussed as a multidimensional process in the field of cross-cultural study. Klein (1979) defined adaptation as a process of attitude or behavior changes in response to new stimuli. Grove and Torbiorn (1985) examined the changes observed over time in an interactive activity between cognitions and behaviors under highly unfamiliar environments. Similarly, Hannigan (1990) regarded adaptation as the change in the cognition, attitude, behavior, and psychology of people who live in a foreign culture. …
