Due to the decline in birth rate, there has been an increase in the immigrant workers who cover the 3K work (Kiken-danger, Kitanai-dirty and Kitsui-tough) which resulted to various social phenomena in Japanese society. However, the issues of medical service (insurance) system to immigrant workers are veiled. In fact, lack of the medical service to the workers has been discussed in the community level such as in Honjo area as a very big issue. For example, nearly 3, 000 immigrant workers from South-America are engaged in the work of 3K around Honjo city in Saitama prefecture. Through a conducted research, most laborers hold a working visa and are united with the community where they live. However, when they are not registered in the health insurance, they cannot afford the medical treatment because it is expensive so they rely on over the counter medicine. 

        As most immigrants are contract labor, the employer does not register them for social security pension or social insurance. Therefore, theoretically, immigrant workers must be covered in National Health insurance; however, not many are covered. Even at the present, there are Japanese who can not pay the national insurance (¥13, 300) which is a social issue. Much less, the　immigrant workers with lower payment can not afford economically to pay for the insurance. In other words, the immigrant workers have less income compare to the Japanese but they both have the same amount of expenses which is illogical. It is not only economic/social difference of the Nikkei immigrants, but also the idea and life style difference towards sickness that creates difficulties between them and the Japanese doctors for communication. There is a need to resolve these　misunderstandings and the doctor’s attitude towards foreign patients as there are differences in the social behavior and detail explanation of sickness between a multicultural South American society and a monoculture society of Japan. 

        With the support of Idente Missionaries in Rome, a Nikkei Peruvian doctors is invited to collaborate in partnership with Japanese doctors (Prof. Nakamura and Prof. Wakasugi) to build a methodology of South American version of medical system from a socio-anthropological point of view. This methodology ought to assimilate in Japanese society. The Institute of Medical Anthropology would act as an advocator to improve treatment towards immigrant workers and as an outcome it aims to eventually establish a clinic.

First year:
1) The basic research will be done by Dr. Marisa Tsuchida (Japanese-Peruvian). The research area will be Saitama and Gunma prefecture where most of Latin American workers are residing. The research will be on collections of folk level concept of sickness, healing, folk medicine and what kind of sickness they would have.
2) The house hold and community structure.
3) How they can adjust to the Japanese community (ex. Honjo city case). 

Second year:
1) The comparative studies on comprehensive expressions of diseases.
2) The analysis of indigenous hearing system in South America.
3) Then the outline of the concept of Medical Anthropology in these areas. 

Third year:
1) Consideration of the establishment of the Clinic Service Center for the Immigrant workers.
2) Recommendation to Japanese government to frame the policy on the protection to immigrant workers.

 Fourth year:
 Research of the interaction of Latin American immigrant’s in seeking health in clinical and non-clinical settings. This research is currently going on. This research in clinical settings allows us at the same time to support Latin American patients and their families with translation and culturally sensitive explanation to Japanese Medical Doctors
