Sano, in the southwestern corner of Tochigi Prefecture bordering Gunma and Saitama, is a traditional castle town and manufacturing city famous for its Sano Ramen — a rich soy sauce-based noodle soup with firm hand-stretched noodles that has developed such a devoted following that Sano holds the highest ramen restaurant concentration per capita in Japan, making it a pilgrimage destination for ramen enthusiasts across the country. Sano Onsen Tochigi draws on chloride-rich thermal waters from the geological resources of the southwestern Tochigi zone, offering warming baths in a ramen-renowned city whose thermal traditions complement the distinctive food culture of one of Japan's most significant regional ramen cultures. The Sano Ramen Museum and the dozens of traditional ramen shops throughout the city, the Sano Premium Outlets shopping destination, and the Sagimatsu Shrine and traditional castle ruins above the city create an appealingly diverse and gastronomically rewarding spa destination in southwestern Tochigi Prefecture.
