Tunnel Fortifications of Imperial Japan Along the Coast of Songaksan Mountain, Jeju

Built around 1945, this facility was a military installation constructed by the Japanese army — facing defeat in the final stage of the Japanese colonial period — for suicide attacks using small boats laden with explosives against the Allied fleet approaching by sea. The tunnels take the form of a straight line, an 'H' shape, or a 'ㄷ' (U) shape, and seventeen of them were cut along the coastal cliffs of Songaksan Mountain on the south-eastern side of Jeju Island. Built by forcibly mobilising the residents of Jeju Island to bore through the coastal cliffs, this facility vividly testifies to the site of Japanese aggression, while also offering a stark, realistic picture of the brutality of war and of a war that forced people toward death.
