This is one of the seven public bathhouses run directly by the city.
This onsen is situated in Kanazawa Village, one of the post towns along the Koshu Road that connected Nagano and Yamanashi Prefectures to Edo (modern-day Tokyo).
The name “Kinkei” comes from the nearby site of Kinkei Gold Mine, dug by the famous Japanese warlord Takeda Shingen in the Sengoku period (over 500 years ago).
Popular among locals and national tourists alike, this bath is considered to have a prolonged warming effect. It is an alkaline spring, which is believed to be beneficial against neurotic disorders, sensitivity to cold, recovery from fatigue, muscle ache, arthralgia, motor palsy, bruises, sprains, hemorrhoids, and digestive conditions.
