Gunma Prefecture

Gunma is a mountainous, landlocked prefecture on Japan's Honshu Island. It's known for its hot springs (onsen) and ski areas. The small town of Kusatsu has more than 100 hot springs, most famously Yubatake, a large pool fed by steaming mineral water gushing down a wooden chute. Set 1,200 meters above sea level, Kusatsu also has skiing and hiking trails.
