History and Characteristics of Minakami Onsen Resort
Hot Spring History Spanning Over 400 Years
The discovery of Minakami Onsen dates back to the 16th century during the Warring States period.

Initially used as a healing hot spring by local people, it gradually became known as a hot spring destination along highways during the Edo period.
After the Meiji era, with the development of transportation networks, it developed into a full-fledged hot spring resort. In the early Showa period, it gained fame as a hot spring destination visited by literary figures and artists, and was beloved by many cultural figures including Wakayama Bokusui. Particularly during Japan’s high economic growth period in the Showa era, large-scale inns were built one after another alongside the boom in group travel, and it grew into one of Gunma’s most representative hot spring resorts.
