All nations glorify death in combat, but Imperial Japan probably more than most. For example, most American movies made during WWII depicted heroic US soldiers defeating the enemy (think John Wayne). But Imperial Japanese movies made during wartime (e.g. Chocolate & Soldiers, made in 1938 during the China Conflict) often depicted the heroic sacrifice of their protagonists. This trend persists today.

This anthem from a film about the Russo-Japanese War depicts glorious death in combat.
