Question

Why did the Allies capture so few Japanese soldiers when they attacked Iwo Jima?

Answer 1

I believe its because they would rather die than be captured by the allies so they began killing themselves.

Answer 2

At the Battle of Iwo Jima, the Allies captured so few Japanese soldiers because the Japanese military tradition made them prefer to die rather than be captured by the enemy, since death in battle was considered an honorable death.

In fact, of the 20,919 Japanese soldiers that participated in the battle, only 216 were taken prisoners, while the other 20,703 died during the combat.
