Nestled in the mountains of Gunma Prefecture, just a few hours from Tokyo, lies Kusatsu Onsen—renowned as one of Japan’s most famous and therapeutic hot spring towns. Praised for centuries, this onsen destination is consistently ranked #1 in Japan due to its mineral-rich waters, traditional atmosphere, and breathtaking alpine scenery.
Kusatsu Onsen is said to cure every ailment except a broken heart. The hot spring water here is extremely acidic and full of minerals, flowing directly from the active Mount Kusatsu-Shirane. With over 32,000 liters gushing out per minute, it’s also one of the most voluminous hot spring sources in the country.
💦 Yubatake – The Heart of Kusatsu
At the center of the town is the iconic Yubatake (Hot Water Field), a cascading series of wooden channels where steaming water cools and minerals are collected. The sight is mesmerizing—especially at night when the mist and lights create a mystical atmosphere. You can soak your feet in free public footbaths nearby or explore charming ryokans (Japanese inns) that offer full-body bathing in traditional wooden tubs.
🧖 Experience the Timeless Bath Culture
Kusatsu is also known for its yumomi ritual—a traditional method of cooling down the water without diluting its mineral properties. Performed by women in colorful yukata, this dance-like ceremony takes place daily at Netsunoyu Hall and offers a cultural glimpse into Japan’s historic bathing traditions.
In addition to outdoor public baths like Sainokawara Rotenburo, surrounded by forest and natural rocks, there are many indoor onsen facilities where visitors can enjoy private, serene relaxation.
🏞️ Nature and Activities
Kusatsu isn’t just for soaking. In the winter, it transforms into a ski haven, while in warmer months, nearby hiking trails and volcanic parks make it a year-round destination.
