天空に輝くエメラルド 「草津白根山」湯釜空撮　Emerald Crater Lake from the Sky – Mt. Kusatsu-Shirane

所在地：群馬県吾妻郡草津町
標高：2,160 m
山系：関東山地（活火山）
特徴：日本百名山のひとつ
草津白根山は活火山で、山頂付近には噴火口や火口湖が点在しています。
特に有名なのは、**湯釜（ゆがま）**という直径約300mの火口湖。水は強酸性で、絵の具を溶かしたような鮮やかなエメラルドグリーンに輝きます。
噴火活動は古くから記録があり、2018年1月にも本白根山で小規模噴火が発生しました。
活動度が高いため、噴火警戒レベルによっては登山規制や立ち入り制限が行われます。

Mt. Kusatsu-Shirane is an active volcano located in Gunma Prefecture, Japan, rising 2,160 meters above sea level.
It is famous for its beautiful crater lake Yugama, whose emerald-green water comes from strong volcanic activity and high acidity.
The volcano has a long history of eruptions. The earliest known major eruption occurred around 1108 AD, when ash fell across a wide area of central Japan. Since then, Mt. Kusatsu-Shirane has repeatedly produced phreatic eruptions (steam-driven explosions), rather than large lava flows.
In modern times, notable eruptions include:
1805: A large steam explosion caused casualties.
1919: Another powerful eruption reshaped the crater area.
2018: An unexpected eruption at Mt. Moto-Shirane sent rocks toward a ski resort, resulting in injuries and one fatality.
Because of its activity, entry to certain areas may be restricted depending on the volcanic alert level. Visitors are encouraged to check the latest information before hiking.
Despite these risks, Mt. Kusatsu-Shirane remains a highlight for travelers, offering dramatic volcanic scenery, unique alpine plants, and access to the famous Kusatsu Onsen, one of Japan’s most celebrated hot springs.
