Imari Kawanami Shipyard, Japan

Imari Kawanami Shipyard is one of the most famous abandoned sites in Japan. The shipyard was built in 1851 to store boats and torpedoes including the infamous Kaiten (Human Torpedo).

Human torpedoes were secret naval weapons in which pilots rammed the vehicle directly into their target. During the war, Imari Kawanami housed around 2,500 soldiers, but it closed down in 1952.
