Kode no dokutsu

This dive site, known as Kode no dokutsu, offers a unique underwater cave exploration experience. Beneath the surface, divers navigate an extensive cave system, stretching 25 meters long and 10 meters wide. The cave's exit emits a distinctive blue glow, guiding divers through its relatively shallow passages where movement can be slow and deliberate, allowing for thorough exploration of its unique features.

The diverse marine life within the cave includes schools of lanternfish that illuminate the upper sections. Groupers and shrimp are particularly abundant, thriving in the darker environment. Tiger fish inhabit the shallower, deepest parts of the cave, while large rays and sharks, including dogfish sharks, are frequently spotted resting inside, benefiting from the shelter and proximity to the open ocean.

Kode no dokutsu is cherished by divers for its stunning visual displays and the allure of cave diving in a non-technical, relatively shallow environment. The thriving ecosystems within the cave, especially the variety of fish and larger marine animals, make it a captivating location. While no specific best time to visit is mentioned, the opportunity to explore these vibrant underwater caves remains a significant draw for intermediate divers.
