Hikiiwa-gun

Hikiiwa-gun is a rock formation in Inarichō, Japan, consisting of tall sandstone columns arranged in a linear pattern rising from the coastal landscape. The individual structures were shaped by natural weathering over centuries and define the appearance of the local coastline.

According to local narratives, monk Kobo Daishi attempted to construct a bridge between mainland Japan and Oshima Island at this location. This story has shaped how people have understood these rock formations across the generations.

The sandstone formations hold religious significance in Shinto practices, where they represent the presence of Kami and serve as natural altars.

The formation is reachable by local transportation services in Inarichō, with designated parking areas near the site. Access is best during low tide when more of the rock structures become visible.

Each sandstone structure within Hikiiwa-gun displays distinct geometric patterns formed by centuries of wind and water erosion along the coast. These natural patterns vary by location and season, making each visit different from the last.
