Geological Features: Hashiguiiwa Rocks is a formation of over 40 massive rock pillars aligned parallel to the coast for approximately 850–900 meters. These rocks were formed about 15 million years ago from magma that intruded from underground and solidified. The remaining pillars are more resistant to sea erosion than the surrounding rock, which has been gradually worn away by waves.

Legend: The name “Hashigui” (橋杭) means “bridge pillars,” originating from a local legend. According to the story, the monk Kukai (Kobo Daishi) attempted to build a bridge from the mainland to Oshima Island in a single night. However, a demon interfered, and by dawn, the bridge was unfinished, leaving only the standing rock pillars visible in the sea. This legend explains both the name and the breathtaking scenery.

Highlights and Activities:
