Bizen

This dive site, located on the west side of Kushimoto in Japan, offers a deep diving experience, reaching depths of approximately 18m below the anchor. The area features two large roots near the anchor, creating a channel for divers to explore. The sandy areas on the west and south sides provide a nesting ground for cuttlefish depending on the season.

Lastly, the presence of gimpfish can be enjoyed year-round around the large roots.
