Kazo, in the northern Saitama Prefecture along the Tone River, is a traditional textile and agricultural city whose Kazo kasuri — a resist-dyed cotton fabric produced in the area for centuries — represents one of the most distinctive textile craft traditions of the northern Kanto region, the bold indigo kasuri patterns adorning the traditional work garments of the Kanto farming communities. Kazo Onsen Saitama draws on sodium and bicarbonate thermal waters from the geological resources of the northern Saitama lowlands, offering restorative baths in an agricultural city whose textile heritage, the Tone River waterway culture, and the traditional northern Saitama farming community create a quietly dignified and craft-conscious spa setting. The Kazo kasuri textile tradition, the Tone River cycling and walking paths through the broad flat Kanto plain, and the traditional Saitama natto soybean and thick udon noodle culture of the northern prefecture make Kazo an appealingly traditional and agrarian spa destination in northern Saitama Prefecture.

Insider tip — Kazo sits on the northern Kanto Plain at the confluence of the Tone and Watarase rivers, a flat landscape of rice paddies and kite festivals for which the city is famous. Its bicarbonate thermal water surfaces from deep alluvial sediments and is prized for soft, alkaline bathing that conditions the skin. The spacious bath house is a local institution where farmers and commuters mingle over long soaks.
