Shinobi (2005)

Synopsis
Enraged by decades of treachery and mistrust, two magical samurai clans go to war despite the love that was meant to keep the peace in director Ten Shimoyama's feudal action entry. The year is 1614, and Japan has been unified under supreme shogun Tokugawa. Though the love shared between Gennosuke of Kohga and Oboro of Iga should have been enough to end the cycle of suffering and strife in the two warring villages, the spirit of vengeance has gained too much momentum and the people have become possessed by their own insatiable rage. Now, as a conspiracy set into motion by Tokugawa causes the violence to swell yet again, Gennosuke pushes for peace as Oboro chooses to fight. In a time when every ninja in the land has been bestowed with amazing superhuman powers, the ultimate war is about to get under way. ~ Jason Buchanan, All Movie Guide
