Having a 2,000-year history, Ikaho Onsen is one of the most well-known spa resorts in Gunma. Mizusawa Kannon is a Buddhist temple of Tendai sect located in the mountains near Ikaho Onsen. On the temple grounds, there are several temple buildings and many gift shops. The gift shops sell Mizusawa Udon (noodles made of wheat flour), which is one of the three major wheat noodles in Japan along with Inaniwa Udon of Akita Prefecture and Sanuki Udon of Kagawa Prefecture. Mizusawa Kannon is where mystical energy is thought to be flowing.
