Zabuza and Haku's Grave

Zabuza and Haku's grave is the place where Zabuza Momochi and Haku were buried after their deaths at the Great Naruto Bridge in the Land of Waves. It overlooks the bridge, and Haku's belt, along with Zabuza's sword were placed there in their memory. In Part II, Suigetsu travels there in order to retrieve Zabuza's sword. This plot is expanded on in the anime, in which Tenzen Daikoku had beaten Suigetsu to the grave, forcing him to track down the blade.
