This beautiful 2-km-long river gorge, Oni-no-Shitaburui, is located in Okuizumo Town, Shimane Prefecture. The shapes of the rocks and boulders here have been carved out over thousands of years by the waters flowing through the gorge, and visitors here never tire of the amazing views. It really gives you a sense of the grand scale of your natural surroundings.
There are two main courses for enjoying Oni-no-Shitaburui Gorge:
① a course where you can enjoy strolling alongside the river, and ② a barrier-free course that can be enjoyed by people with mobility restrictions or small children in strollers.
Both courses give you the opportunity to enjoy Oni-no-Shitaburui from different perspectives, so you can even hike out on one and hike back on the other!
Of the many boulders and rock formations you can see at Oni-no-Shitaburui Gorge, one that stands out is Oni-no-Shito-iwa, a boulder that has been split in half. It is said that a demon tested out the cutting power of his sword on it, which is how the boulder gets its name. (“Oni” means “demon”, and “shito” means “to test a sword”.)
Recently, this boulder has become popular amongst fans of the anime Demon Slayer: Kimetsu no Yaiba, as it resembles a boulder that the main character cut in half during his training.
At the Okuizumo Tatara Sword Museum, about 15 minutes by car from Oni-no-Shitaburui Gorge, there is a black sword on display which is very similar to the black sword that the main character of Demon Slayer: Kimetsu no Yaiba uses.
From a rock that looks like a demon crying, to a boulder that looks like the profile of a tengu (a legendary Japanese creature), there are many other features of the gorge to discover as you enjoy a wonderful nature walk!
