As some of you might know I had a great time during my summer vacation. I visited various places, but today I want to share one of my highlights with you: The Yugama Crater Lake of Mt. Shirane
Favorite Photo #4: Crater Lake Yugama
*Click to enlarge
What you see in the photo is one of the three crater lakes of the volcano Mt. Shirane (白根山).
It is a 2160 m active volcano in Kusatsu, Gunma Prefecture. It’s called Kusatsu Shirane (草津白根山) to avoid confusion with Mt. Nikko Shirane (日光白根山）on the other side of Gunma Prefecture.
“Yugama” (湯釜, lit.: hot water pot) is the largest of Mt. Shirane’s crater lakes and looks stunning with its turquoise color and with rafts of yellow sulfur floating on its surface. The caldera lake measures 300m in diameter and 30m in depth and the water temperature is approximately 18°C.
Because of its very high acid level of about PH1.0, plants cannot grow around this lake.
You can easily access “Yugama” by bus from Kusatsu’s bus terminal and then hike up for about 20 minutes. It’s an easy hike!
Important visitor’s note:
Hiking is only possible from mid April to early November!
Yugama is a stunning site – a lot more breathtaking than any photo can express!
The nearby Kusatsu Onsen Resort is also totally worth a visit. You can easily do both as a day trip if you are already in Gunma Prefecture.
