Lake Mashu

Map

History & Origins

The name of the lake is said to derive from the Ainu language, but there are various theories about its etymology. It became known nationwide through the popular song 'Kiri no Mashuko' (Misty Lake Mashu), released in 1966. A folk belief that travelers who see the lake wrapped in mist will marry late in life is also handed down.

Highlights

Its greatest feature is a mysterious landscape cut off from the outside world, with no inflowing or outflowing rivers and steep caldera walls all around. On clear days the lake surface shines a deep blue called 'Mashu Blue.'

Visitor Guide

You can look down on the lake from three viewpoints: the First Observation Deck (Kamuy Terrace), the Third Observation Deck and the Ura-Mashu Observation Deck. Access to the lakeshore is not permitted. On summer early mornings, when mist forms easily, the atmosphere is especially magical.

Best Season

July-September is the sightseeing peak, and summer is also when you can see the mysterious misty scenery. Early mornings in autumn (September-October) have a somewhat higher chance of clear skies.
