What is there

In a residential quarter east of Morioka station, a small shrine stands in front of three granite boulders taller than the houses around them, with a gap between the stones and a rope across the largest. The handprints are said to show on the rock face after rain. The shrine is plain, the grove is quiet, and the place is best known for the summer dance of Morioka, whose drummers and dancers trace their festival to the oath sworn here.

Why here

A demon called Rasetsu had been robbing the valley, and the people prayed to the god of the three stones. The god bound the demon to the rocks, and the demon swore never to come back, pressing its hands into the granite as the seal of its oath. The name of the prefecture, Iwate, is read as “rock hand”, and the old name of the castle town, Fukōzu, as “never to come”; the people’s dance of joy at the demon’s going became the Sansa dance of August. The oni of this tale is the kind that can be bound and made to keep its word.
