High-current coral point in Shikoku
Local boat operators usually choose this site only when tide and sea state are favorable.
Kurohae is a National Park Special Protection Area reef point in southwestern Shikoku, known for very fast currents, dense fish life, and a compact mix of hard-coral and soft-coral habitat. It is the kind of site you plan around slack tide rather than around convenience, but when the sea is right it delivers a striking, high-energy coral-and-fish snapshot of the region.

Safety Notes
Treat Kurohae as a strong-current dive and avoid it when the tide is moving hard. Plan the dive around slack tide and favorable sea conditions.
Access Restrictions
This National Park Special Protection Area site is typically dived only when the tide is slack and conditions are favorable.
Legal Notes
Respect National Park Special Protection Area rules and local guide instructions.
Community notes to help plan your visit.
Scuba Diving
A current-sensitive coral reef point that rewards careful slack-tide timing and good buoyancy control.
Freediving
Not a freedive-friendly planning choice except for very experienced divers working with local conditions.
Snorkeling
Not a practical snorkeling site because the useful water is current-sensitive and best left to scuba profiles.
