This is not a warship. This is a small island "Gunkanjima" located in western Kyushu. Once upon a time, coal was produced around Gunkanjima. Many miners and their families lived there. Even today, Japan's first high-rise houses are left. The island is currently registered as a World Heritage Site. To go to Gunkanjima, I recommend taking a tour from Nagasaki Port.
