Lake Mashu-ko

Travel Guide - Lake Mashu-ko

Information

Lake Mashu-ko is is about 15 kilometers south-east of Kawayu Onsen Hot Spring.
This a crater lake formed by an eruption 7,000 years ago.
It is said that the lake is always in the mist and fog, and this makes the lake very mysterious.
Known to the Ainu as the "Kamuito (Lake of Gods)", there is certainly an unusual atmosphere to this lake, which is surrounded by steep rock walls that reach a height of 300 meters.
You are very lucky if you can see a clear sight of the lake.

Since the lake is a crater lake and there is no rivers that flow in or out of the lake, the clarity of the water and its intense blue color is quite startling - its transparency depth of over 35 meters is said to be one of the deepest in the world.

Visitors can view the lake from three observation points.
From observation point No.
1 you can hike to Mt.
Mashu-dake, the craggy volcanic peak that lords over the eastern shore of the lake.
Allow about six hours for the return trip and walk with care.

Draining the swamp? It's more like draining Lake Mashu & filling up with nuclear waste. Godzilla's from industrial waste. What will this be?
