Additionally, rice cooked with this soft, cold water and drip coffee made with it are highly praised for their unique taste.Located at an altitude of 1,350 meters, the shores of Lake Onuma are about 10°C cooler than the city center, making it an ideal summer retreat, often referred to as "the entire mountain is air-conditioned." In winter, the area experiences cold temperatures comparable to Hokkaido, and Lake Onuma becomes a rare spot in the Kanto region for ice fishing for smelt. From September to November, boat fishing is also available.
