400 metres of cave dug by hand, opened in 1931 as the lair of the oni of legend.

About 400 metres long and largely man-made, not formed by natural processes, the cave extends into Mount Washigamine, with a large hall, a ‘treasure’ room and a cell for prisoners: tradition holds it to be the lair of the oni (demons) of Momotarō, with statues of demons added along the route.

A cave on Mount Washigamine, in the upper part of the island of Megijima (女木島), also known as Onigashima (‘the island of demons’) for its link with the legend of Momotarō. Reported in the early twentieth century by the local historian Hashimoto Sentarō, it was opened to the public as a tourist attraction in 1931.
