Sonatine (ソナチネ Sonachine) is a 1993 Japanese film by Japanese filmmaker Takeshi Kitano. It won numerous awards and became one of Kitano's most successful and praised films, garnering him a sizable international fan base.
Kitano plays Murakawa, a Tokyo yakuza tiring of gangster life. Along with some henchmen, he is sent by his boss to Okinawa supposedly to mediate a dispute between their allies, the Nakamatsu clan, and the Anan clan. Murakawa openly suspects that the assignment is an attempt to have him removed and even beats up one of his colleagues, Takahashi, who he distrusts, but ends up going with his men. He finds that the dispute between the clans is insignificant and while wondering why he was sent to Okinawa at all, the group's temporary headquarters are bombed.
