Conditions or access may require a local guide. Dive with a local operator.
Mikuni Takara Island West is a shallow boat dive in the Shakotan area of Hokkaido. Clear water, a sheltered bay, and a gently sloping seabed make it a good fit for training dives, relaxed macro hunting, and snorkel-friendly summer days. Local operators run seasonal boat trips from the port, and the site stays seasonal because Hokkaido wind, swell, and water temperature still shape the day.

Freediving
The shallow bay may allow calm breath-hold practice, but the site is better treated as a guided boat dive than a dedicated freedive spot.
Snorkeling
Snorkeling is plausible in calm summer water because the site is shallow and clear, but boat and weather planning still matter.
