The Only Son

In the outskirts of Tokyo, a poor but close-knit group living on the fringes of society survives through shoplifting and odd jobs. When Osamu and his son take in a neglected young girl, their already fragile existence begins to unravel. As the family grows attached to her, buried secrets surface, forcing them to confront the true meaning of love, belonging, and what makes a family.

The elderly Shukishi and his wife, Tomi, take the long journey from their small seaside village to visit their adult children in Tokyo. Their elder son, Koichi, a doctor, and their daughter, Shige, a hairdresser, don't have much time to spend with their aged parents, and so it falls to Noriko, the widow of their younger son who was killed in the war, to keep her in-laws company.

In a small Tokyo apartment, twelve-year-old Akira must care for his younger siblings after their mother leaves them and shows no sign of returning.

Shuhei is leading a tough life. His alcoholic mother Akiko can only hook up with bad guys and order Shuhei to go get money from his disapproving grandparents instead of going to school. Except raising the little half-sister, his rock-bottom life seems to have no end.

Widower Shuhei Hirayama's caretaker is his 24-year-old daughter, Michiko. Gradually, he comes to realize that Michiko should not be obliged to look after him for the rest of his life, so he arranges a marriage for her.
