IJA tropical tunic. While this is not a terribly rare item this example is very nioce on grounds of condition being just about mint. I find no damage or even wear anywhere on this. The armpits are open for air circulation. The tag is under the loop on the back of the neck. Markings included inspection information, identify this as Type 98, size 3. The date is Showa 18 or 1943. Perfect example.
