摩周湖は北海道の弟子屈町にある湖である。「霧の摩周湖」でも有名、というよりも「霧の摩周湖」のおかげで摩周湖が有名になったと言う方が正しいかも知れない。湖を囲むその特徴的な地形から霧が発生しやすく、そして停留しやすい。摩周湖は透明度も極めて高く、世界第二位の透明度を誇る。その理由のひとつが、この湖に流れ込む河川が存在しないことが挙げられる。また、ここから流れ出る河川も存在しない。それなのに、この湖の水は年間を通してほぼ一定。どこかからか湧水があるらしいが、詳細は全く不明である。そもそも、河川もないこの湖を「湖」と呼ぶことは法律的には正しくなく、実のところは「大きな水たまり」という方が正しい。

Lake Mashu is a lake located in Teshikaga, Hokkaido. It is also known as “Foggy Lake Mashu,” or perhaps it is more accurate to say that Lake Mashu became famous thanks to “Foggy Lake Mashu. The lake is surrounded by a unique terrain that makes it prone to fog and mooring. Lake Mashu is also extremely transparent, and is the second clearest lake in the world. This is partly because there are no rivers flowing into the lake. There are also no rivers that flow out of the lake. And yet, the water in this lake is almost constant throughout the year. It is said that there is a spring from somewhere, but the details are completely unknown. To begin with, it is not legally correct to call this lake a “lake” as there is no river, but in fact, it is more accurate to call it a “big puddle”.
