There are many organizations of companies from same hometowns at Naha-city, Okinawa prefecture. But these days, their action has been declined because of the reason of being aged and decrease of immigrants. Firstly, I researched the role and the specialty of the company. From the result of this research, I proved the declination of the company's action is not the same as declination of the company itself, and the importance of school-mate-connections. Secondary, I understood the specialties of the company and picked up some characteristic lifestyles, and clarified that their thinking tendency depends on the term from their leaving to today.
