Located only a short 45-minute drive from New Chitose Airport and one hour from Sapporo, Lake Shikotsu is one of the clearest, northernmost lakes in Japan that never freezes. The clarity of the water has little competition and owes its high transparency to the low number of plankton and minimal nutrient content. Due to its unique properties, the lake has been lauded as the nation’s highest quality source of water for 11 years in a row! Visitors trekking to Lake Shikotsu should not miss its fantastic sightseeing cruise! Enjoy the amazing underwater view while on board a glass-bottomed boat. We also recommend rental boats that are easy to operate and the “clear kayak” tour which gives you the feeling of floating on the lake.
