Hashima Island, located off the coast of Kyushu Nagasaki, is a coal mining facility that is now in ruins, called Gunkanjima because of its shape. It can be reached by boat in 40 minutes from Nagasaki Port, so you can go ashore on a tour, but from the coastline of the Nomozaki area in the southern part of Nagasaki City, you can see Gunkanjima from land. This view is also a view that I would like to keep forever, but it may not be possible to see it in a few years due to the progress of decay.
