Of more contemporary and controversial interest is Matsushiro Daihonei (Zozan Underground Imperial Headquarters) - a complex of subterranean tunnels dug by Korean forced-laborers in a bid to provide an impregnable sanctuary for the Emperor and the organs of the Imperial Japanese government at the end of World War II. A 500m-stretch of tunnel can be entered and there is a small museum adjacent to the main entrance detailing the brutality of the treatment meted out to the construction workers on the site.
