Tannaisan Shrine, an Ancient Sanctuary of the Arahabaki Deity in Hanamaki

Set in Yachi, Towacho, Hanamaki City, Tannaisan Shrine is an ancient sanctuary known mainly to those in the know. Shrine tradition holds that it was founded by Nikko, a disciple of the great monk Kobo Daishi Kukai, and that it was once called Daishoji. It is said to have been deeply revered by leading warriors of their ages such as Sakanoue no Tamuramaro and Minamoto no Yoriyoshi, marking a long history.

In recent years the shrine has drawn attention for the giant Arahabaki deity rock that serves as its sacred body. The rock has a cave-like hollow, and legend says that if you pass through it without touching the walls, your wish will come true. It is a place wrapped in a distinctive air that carries echoes of ancient nature worship.

Highlights

• The giant Arahabaki deity rock, where passing through without touching the walls is said to grant wishes

Enjoying the Seasons

In spring the trees around the grounds bud and fresh greenery spreads through the quiet hills. In summer deep green surrounds the site and the air around the great rock stays cool.

A Quick Tip

When passing through the giant rock, take care literally not to touch the walls. Keeping the wish-making manners in mind makes the visit feel all the more special. The surroundings are a quiet mountain hamlet with limited public transport, so visiting by car is reassuring. Allow plenty of time to feel the presence of ancient faith.
