Hello Japan - Japan Travel Guide


Travel Guide - Yugama


"Yugama (boiling pot)" is the name of a crater lake located at the top of Mt. Kusatsu-Shirane-san. It is 300 meters in diameter and 30 meters deep. Because of the high altitude of over 2,000 meters, it is cold around the lake even during the summer, but the water of the lake never freezes all year round thanks to the boiling sulfurous spring bubbles up from the bottom. The lake is world famous for its extremely high acidity (around pH1.0). You can observe the emerald green surface of this mystical looking lake from the observation platform.
