Isesaki, in the southern Gunma Prefecture plain along the Tone River, is a historically significant textile city whose Isesaki meisen — a distinctive kasuri-dyed silk fabric featuring bold geometric patterns that became fashionable in Meiji and Taisho-era Tokyo — represents one of the most innovative and commercially successful textile traditions in modern Japanese fashion history. Isesaki Onsen Gunma draws on sodium and bicarbonate thermal waters from the geothermal resources of the southern Gunma plain, offering restorative baths in a city whose dynamic textile heritage and traditional Kanto plain agricultural character create an interesting urban spa setting in the flat southern Gunma lowlands. The Isesaki Meisen Museum documenting the kasuri silk tradition, the traditional machiya weaving townscape of the historic textile district, and the Tone River cycling paths through the broad Kanto plain landscape create a pleasantly varied backdrop for thermal spa relaxation in southern Gunma Prefecture.
