The surreal world headquarters of the Japanese new religion of World Divine Light (世界真光文明教団 Sekai Mahikari Bunmei Kyodan) looks like something straight out of anime, with a cantilevered five-level temple roof perched on a remote hillside. Known of its divine light healing rituals, the religion is widely considered a cult, but visitors are welcome (although two days' notice is requested) and generally not subjected to conversion attempts.

Shuzenji Temple has a small museum with some nice artifacts that are related to its founder, Kobo Daishi.

A cedar-lined public bath built in 2000 by the tourist association. Also has a three-story tower that gives a nice view over the roofline of the town.

A large amusement theme park on nature and British architecture with a Canadian village, an English village, and completed with a train and a Japanese garden.

独鈷の湯
The historic spot where Shuzenji's springs were first discovered by Kobo Daishi. A small public rotenburo (open-air bath) in the middle of the town center — but it's not for bathing your whole body, only your feet!
