Hospitalité (2010)

Mikio Kobayashi (Kenji Yamauchi) lives quietly with his wife (Kiki Sugino), daughter (Eriko Ono), and divorced sister (Bryerly Long) in downtown Tokyo, where xenophobic neighbors insist they attend community watch meetings, and the only recent excitement is the disappearance of a pet parrot. One day Kagawa (Kanji Furutachi) appears, claiming to be the son of a financier who once helped Kobayashi's company. Kagawa soon ingratiates himself as a live-in employee and proceeds to comically turn the Kobayashi's monotonous life upside down with his odd behavior, unexpected visitors, and bizarre schemes.
