Sway (ゆれる, Yureru) is a 2006 mystery-drama film, directed by Japanese director Miwa Nishikawa, which features sibling rivalry and a possible murder.

Takeru's older brother Minoru (Teruyuki Kagawa) quickly intervenes and soothes their father with drinks and sympathetic comments.

Takeru later learns that his brother has taken over their family business, a run-down garage, and that his ex-girlfriend, Chieko (Yōko Maki), now works there as a gas attendant.

Minoru realises something has happened between his younger brother and Chieko, and suggests they all should go for a walk along the Hasami River in the mountains where Takeru could take photographs.

As the case proceeds during a courtroom trial, Takeru begins to doubt his testimony when he realises hidden resentment and deeply buried anger between Minoru and himself, which may have affected what he witnessed on the bridge that afternoon.
