Lake Shikotsu has three unique characteristics. First, it is known for its crystal clear water. Second, it is the second deepest lake in Japan (after Lake Tazawa), with a maximum depth of 363m and an average depth of 265.4 m. Finally, it is unfrozen even in winter. In fact, it is the northernmost ice-free lake in Japan.
Look at the clear water!
