Kanokawa Nakanose is a calm-current reef area near southern Iriomote Island. The dive combines lush coral gardens, including thistle corals, with seasonal wildlife shifts that move from winter manta encounters to summer schooling fish and pelagic visitors. It is best approached as a boat dive where current windows and steady pacing matter more than rushing the reef.
Safety Notes
Confirm the boat plan and current window before entering. The site is known for calm current, but marine traffic and sea state can still change the feel of the dive.
