In Europe, the FilmStim database which can arouse specific emotion was edited. In this study, we examined whether the FilmStim can be applied to Japanese. And we investigated the relationship between brain activity and positive and negative emotion by using NIRS. It was indicated the possibility that the emotional score of European can apply to Japanese by explaining contents of film.
