Best for intermediate divers, 3-12m, shore entry, moderate current.
Shikotsuko Lake is a freshwater dive site in Japan defined by a distinct drop-off structure. Divers typically explore between 3 and 12 metres, where a sharp thermocline marks the transition to significantly colder water. The site features moderate currents, requiring careful buoyancy control during shore entries. Visibility ranges from 15 to 25 metres. Due to the cold water temperatures, which fluctuate between 5.5°C and 20°C, drysuits are highly recommended or required for all dives. The site is suited for intermediate divers who should consult the on-site dive shop for current conditions before entry.

Pack a drysuit or a thick wetsuit regardless of season, as the thermocline delivers a sharp cold shock on descent and the deeper water stays cold year-round. The on-site dive shop is worth visiting before entry to get a current conditions briefing, particularly regarding current strength on the drop-off.
The lake is a 40 minute drive from Shin-Chitose Airport, an 80 minute drive from central Sapporo or an hour drive from Lake Toya. Buses to Shikotsuko Kohan operate from Shin-Chitose Airport.
