About Sea Of Okhotsk
Sea Of Okhotsk is a seasonal cold-water diving region in Hokkaido where the defining draw is drift-ice diving around Shiretoko and the wider Okhotsk coast. It is a specialist winter destination rather than an everyday open-water spot, with drysuit conditions, operator-led access, and dramatic ice, rock, and kelp scenery. The reward is a highly unusual winter underwater experience with rare cold-water wildlife and strong visual character on the right day.
