The Crying Wind 2004 one on netflix

Seikichi, makes his living fishing from a small boat off the coast of Okinawa. He and his 12-year-old grandson Akira live in a small, tree-lined village in the northern part of the island which is surrounded by a white-sand beach and plots of pine and flowering bushes. On the cliff that skirts the shore sits an open-air burial ground containing the skull of a kamikaze pilot who was shot down during the last days of World War II. When the wind blows through the bullet hole in the skull, it produces a whistling sound. The locals call it the “Crying Head.”
