Its a love story wrapped up in comedy. A series of pratfalls involving the lead who stumbles through his own life, overshadowed by a famous dad. In the film he aspires to act, and seems to have landed the ideal role, but then gets mistaken for a man having an affair with a politician's wife. On the train he meets a woman, and hopes for romance, but unlike his father, he is nervous and inexperienced around women so needs all the coaching he can get. Watched it in Tokyo and can vouch for it being bi-culturally funny. No ez task. The protagonist has that sad sack appeal that worked so well for Woody Allen.
