Live from Mount Kusatsu-Shirane, this webcam opens a window onto one of Japan's most fascinating volcanic landscapes in Kusatsu, Gunma Prefecture. Rising above the famous hot spring town of Kusatsu Onsen, the mountain is an active volcano whose geothermal energy has shaped the area for centuries. The view often captures sweeping alpine slopes, shifting mountain weather, and the dramatic terrain that makes this corner of Japan feel both serene and powerful.

What makes this place so remarkable is the connection between the volcano and the town below. Kusatsu Onsen is one of Japan's most celebrated hot spring resorts, and its famously mineral-rich waters are naturally heated by volcanic activity beneath Mount Kusatsu-Shirane. The steam, crisp mountain air, and forested ridges create a distinctive atmosphere that changes beautifully with the seasons - snowy and stark in winter, lush and green in summer, and richly colored during autumn.

Nearby, visitors can explore the lively Yubatake hot water field, traditional baths, and scenic mountain trails. The area is also known for its high-altitude volcanic scenery and the quiet sense of retreat that has made Kusatsu a favorite getaway for generations. Watching Mount Kusatsu-Shirane live offers a rare look at the natural force that powers one of Japan's most iconic onsen towns.
