Same thing happened to me in Korea.
Hope you guys have read it.
Now, down in Indonesia there were not large concentrations of Allied troops to hold in camps, but there were plenty of equally quite dangerous Chinese and mixed-blood people (buken asli in the words of Sukarno) the Japanese held in equally bad camps, complete with Korean guards.
A friend of mine was about 12 years old when the Japanese came to Java. Due to his age he was allowed to go in and out of the camp where his older relatives were held. He regularly hunted and dressed an animal that we would call a "RAT", and that was his meat, and their meat, and the meat the Korean guards got as well.
People who tell you folks don't eat dog, or rat, or endangered birds, or cats, or whatever in such and such a country have really never experienced life under the gun of a conquerer.
