Movie,「That is the light of harbor」is the movie considered a sort of the first work describing today`s Korean Japanese in a quandary between ``Japan and motherland``. However, looking into by putting Rhee line issue spreading the movie in the same age and diplomatic talks among Korea, America, and Japan surrounding North Korea repatriation project and South Korea repatriation project in view, the movie amputates and forgets postwar issues of Japanese colonialism by forcing Kimura hiding his birth to coming out, and by stressing capture outside of Rhee line, covers Japanese diplomatic inequality (=a sense of inferiority) not able to assert ``freedom of the seas`` to America but assert the above principle to Korea with a ground of legal interpretation, and justifies Korean iniquity and illegality. Also, in the movie, the reason why Japanese Korean cannot go back to Korea is handled simply as anxiety of Korean situation (don`t have concern why such anxiety was made) and when looking into diplomatic documents relating to Korean repatriation project at the age, Japanese Korean`s Korea repatriation project was a solution prepared led by America to normalize Korea-Japan relationship which was deteriorated by the Japanese government`s approval of Korea repatriation project but couldn`t be realized by the America`s failure to keep their promise of lending compensation money and resettlement funds. Japan succeeded repatriating Japanese sailors arrested in Busan as accusing America of all the things about the America`s failure to keep their promise and disguising Japanese Korean`s Korea repatriation project as rice import issue. That is, the movie focuses on Korea-Japan issue by eliminating America in the complicatedly conglutinating problems among Korea, Japan and America at the age and in the result can be seen as simplifying Japanese Korean issue.
