About Shikotsuko Lake
Shikotsuko Lake is a freshwater dive in Hokkaido known for exceptional clarity, cold-water conditions, and a winter ice-diving season. Most dives are shore-based from the lake side, with easy entry points and a shallow guided dive zone rather than a boat run. The outlet river adds a drift-style option for experienced divers. Seasonal freshwater life includes trout, salmon, carp, shrimp, and occasional birds or plants in the clearer months.
