Worldwar2 imperial japanese army dog tag

This is a Japanese Army dog tag from World War II.

It is written in Kanji as the 2nd Infantry Auxiliary Company No. 13.

Generals were written by name, but soldiers such as infantrymen were written by number in this way.

Japanese soldiers always wore dog tags.

On the battlefield, there is always the possibility of death. The purpose was to have their comrades and family members recognize them after they died.
