|This building is located in Imari harbour in the Saga prefecture, in Japan. It used to be called Kawaminami shipyard, and was originally a glass factory which processes the raw material imported from the Middle East by boat.|
Around the time of the Japan/china war, it became the Kawaminami industrial corporation, and started to produce boats, and later ammunition. I don't have much more information. I particularly enjoy the vegetation overtaking the concrete structures.
