Naganohara: Gunma, Japan: Mt. Asama

The landscape around Naganohara is a steep, forested stretch of the Agatsuma River valley, which has shaped both its linear settlement pattern and local economy. In northwestern Gunma Prefecture, the municipality extends from the river corridor toward upland districts near the volcanic mountains of the Joshin’etsu region. Lake Yamba, the reservoir behind Yamba Dam, is a defining feature of the valley; the dam was completed in 2020. Kawarayu Onsen, a traditional hot-spring district, remains central to Naganohara’s identity despite the changes brought by the reservoir project. The JR Agatsuma Line connects the town with the wider region. Find related webcams across the Agatsuma valley and Gunma Prefecture to build a fuller picture of this mountain district.

Gunma Prefecture is best known within Japan for Kusatsu Onsen, one of the country’s most celebrated hot-spring resorts. Set inland northwest of Tokyo, it spans fertile sections of the Kantō Plain and mountain country along its western and northern edges. The Tone River, Japan’s second-longest river, rises in these mountains and feeds farms, reservoirs and towns. Mount Akagi is a prominent volcanic landmark above the Maebashi area. Gunma also preserves a major chapter of industrial heritage at the Tomioka Silk Mill, Japan’s first modern silk-reeling factory and a UNESCO World Heritage site.
