Kamisuwa Onsen Nanatsugama Spring
- Source
- Nanatsugama spring (Mitsugama No.1 and No.2 springs, Ayame spring, Yanagi-Nami mixed spring)
- Location
- 2-208-90 Kogandori, Suwa City, Nagano Prefecture
- Spring Quality
- Simple sulfur springs (mildly alkaline, hypotonic, and high-temperature)
- Origin of “Nanatsugama”
- Until 1945, this entire area lay beneath the waters of Lake Suwa. Hot spring waters once surged from the lakebed, and while the lake would freeze completely during the bitter winter months, seven specific spots remained unfrozen—giving rise to the name Nanatsugama, or “Seven Pots.”
