Overview

Manza Onsen is a hot spring resort located at an elevation of 1,800 meters in Tsumagoi Village, Agatsuma District, Gunma Prefecture. Along with Doro Onsen in Gifu Prefecture, it's known as one of the highest hot springs in Japan accessible by car year-round. Its history stretches back to ancient times; Yayoi period pottery has been unearthed in the area, and there's a legend involving Sakanoe Tamuramaro subduing demons. While it functioned as a spa town during the Edo period, its significant development began after World War II. Resort development by the Seibu Group improved accessibility, leading to a surge in visitors. Manza Onsen features acidic sulfur springs (hydrogen sulfide springs), characterized by their milky white or yellowish-white waters. It boasts the highest sulfur content in Japan, and the high temperature of the springs creates a breathtaking scene of rising steam. The hot spring town features Ryokans (traditional Japanese inns), hotels, and a ski resort, providing year-round enjoyment. Winter offers skiing and snowboarding. Spring showcases a beautiful contrast of lingering snow and fresh greenery, with vibrant rhododendrons in bloom. Summer offers a cool climate and a profusion of alpine flowers such as the Dianthus superbus. Autumn brings stunning autumn foliage, painting the hot spring town in vibrant colors. Manza Onsen is a highly recommended destination for enjoying nature and hot springs. We encourage you to visit!
