Nishikawana

This dive site, Nishikawana, is located at the scenic tip of Tateyama on the Boso Peninsula in Japan. Accessible only by boat, the underwater landscape features a diverse mix of rocky reefs, gorota stones, and sandy terrain, including a notable V-shaped valley. While no specific historical context is provided, its varied topography offers an engaging experience, though divers should be prepared for potentially fast currents.

The site is renowned for its abundant marine life, particularly larger species. Divers can expect to encounter big fish such as Kue, schools of sunfish, and damselfish. Summer months bring schools of stingrays and large migratory fish chasing baitballs. A unique resident is a huge black sea eel, often observed up close, adding to the site's distinctive appeal.

The best time to visit Nishikawana, especially during the summer, is for the chance to witness impressive schools of stingrays and large migratory fish. Due to the variable currents, intermediate divers are best suited for this site. While the average depth is around 9 meters, making it accessible for freedivers, strong currents would require advanced freediving skills and careful planning for safety.
