Diamond Yukai

Sawaki is a postman who's not quite thrilled about his boring way of life. But his life is about to change when he delivers mail to his old schoolmate Noguchi, who's now a member of the Yakuza, the Japanese Mafia, and just finished cutting his little finger off.

A young rock singer is not appreciated by her band, and gets a postcard from Japan saying "wish you were here". She takes what little money she has including ex-boyfriend's rent money and goes to Tokyo. She has numerous cross-cultural adventures and ends up singing with a Japanese rock group looking for a gaijin gimmick.
