Mitsuishi Shrine

In a quiet residential corner of Morioka stands the modest Mitsuishi Shrine. Within its grounds rise three enormous granite boulders wrapped in sacred straw ropes, long affectionately called Mitsuishi-sama by locals. Unlike the crowded Hiraizumi area, this is a still place where simple, living faith continues to this day.

According to legend, a demon named Rasetsuki once ravaged this land until Mitsuishi-sama captured him and forced him to promise never to do harm again. As proof, the demon pressed his handprint into the rock. This tale is said to be the origin of the name Iwate, which can be read as a hand pressed into stone, and because the demon vowed never to return, the old place name Kozukata (meaning the one who will not come) was also born. It is said that villagers who rejoiced at the demon leaving danced around the three stones chanting sansa sansa, which is regarded as the origin of the Morioka Sansa Odori dance festival.

Highlights

• Three sacred boulders bound with straw ropes, traditionally said to have fallen during an eruption of Mount Iwate, though the Iwate Prefectural Museum records them as granite that formed naturally on the spot
• The rock face bearing the demon handprint, where you can sense the roots of the prefecture name Iwate
• The enshrined deity is Sukunahikona no Mikoto, god of medicine, known for blessings of health and family safety
• A distinct hush surrounds the boulders even in the middle of a neighborhood
• Known as the birthplace of the Morioka Sansa Odori, held in early August, drawing visitors who come to learn the legend during festival season

Enjoying the Seasons

In spring the surrounding trees bud and soft greenery frames the stones. In summer visitors seek the cool shade nearby. During the early-August Sansa Odori season it is rewarding to visit while reflecting on the shrine as the dance festival birthplace. Autumn brings colored leaves that contrast with the heavy gray boulders. In winter, snow blankets the three stones, deepening the tranquil and mysterious atmosphere.

Access and Basic Information

• Location: 2-1 Nasukawacho, Morioka City, Iwate Prefecture
• Access: About 10 minutes by bus or taxi from JR Morioka Station; also walkable from the city center
• Free to visit, no admission fee
• The area sits among a cluster of temples known as Tera-no-shita, making it pleasant to explore on foot

Practical Travel Notes

• Best season: Fresh green in May and June and autumn foliage in October and November suit the contrast between the boulders and nature. The early-August Sansa Odori season, when all of Morioka turns festive, pairs memorably with a town walk.
• Time needed: The grounds are small, so visiting and viewing the boulders takes about 15 to 30 minutes. Allow one to two hours if you include a stroll through the surrounding temple district.
• Avoiding crowds: This is already a quiet spot with few tourists, but a weekday morning is ideal for a calmer visit.
• Real nearby spots: Within walking distance lie temples such as Hoon-ji (famous for its five hundred rakan statues) and Tokengen-ji, and a little farther are Morioka Castle Ruins Park (Iwate Park) and the Ishiwari-zakura cherry tree splitting a granite rock, all easy to combine with the central sights of Morioka.
• Budget feel: Visiting is free. Even with round-trip bus fare from Morioka Station and local specialties such as wanko soba or reimen noodles, this makes an easygoing half-day walking route.

A Quick Tip

This is no flashy attraction, but a rare place to stand at the very origin of the name Iwate. Since it lies within a neighborhood, be considerate of nearby residents and visit quietly. Pair it with a stroll through Morioka to savor the local history more deeply.
