My friend from school days, who is into a digging up lot of WWII stuffs, have a museum in a remote corner of India. Backed by Japan, and the local government, it is located near to other Japanese related location in Imphal, Manipur (INDIA).
Here are some pictures I took while visiting it some time before the official opening. I think I got some of the Indian Currency printed by the Japanese during the war. I might also have copies of some videos from during that time (I think the 40s-50s).
