Oyaji (2007)

Surrounded by violence for as long as he can remember, Ryoudo Numata has steeled himself into a tremendously tough man, growing to become the very essence of "manliness" himself in order to live his life in peace. When members of a yakuza clan set on fire to his house to facilitate a real estate transaction, Kumada murders them and gets jailed for it. 15 years later, finally free, he will now have to reconnect with his family who clearly are in disarray due his long absence and face the distrust of his children who know nothing of their father except that he had abandoned them.
