I still have my Japanese Helmet.
Found in Papuan (New Guinea) jungle at Ioribaiwa the furthest point the Japanese reached on the Kakoda campaign.

Around 1977 I and a few others hiked to Ioribaiwa and looked around. The helmet was in a foxhole and pretty rusty after 50 years in tropical rainforest.
There were also a bunch of cookpots and bottles found in the trenches there. No sign is still obvious, I looked with the perspective "The Australians are on that ridge over there (Imita) and shooting at me, where do I make a foxhole or trench". Then dig.
Most were just filled with leaves and debris, so digging with long pole to encourage inhabitants to leave (venomous snakes)

I did clean it up and lacquered to prevent additional rust.
2 of the 3 anchor points for the liner are still original.

I guess the original user had a shrapnel problem
