Tokuzo Yamada (1885 – 1964), a draper from Takasaki, excavated this cave and opened it to the public in 1963, shortly before he passed away. The attraction includes the cave Kannon and Tokumeien Japanese Garden. Although it has no formal religious denomination, it can be viewed as a sightseeing worship center. In the fall, many tourists come to enjoy the autumn leaves in the garden.
