Named after the warlord Uesugi Kagetora, who met his end at Samegao Castle, the Kagetora no Yu source was drilled in 2017 in the hills of Jinguji, Myoko, below the castle ruins. Piped from the slopes at about 39°C, its dense salty water steeps into the skin and lets warmth linger long after bathing, while iron stains the rocks reddish brown. It suits travelers tracing Sengoku-era history who want to warm up to the core on chilly days.

Yasuda Onsen rises in the farmland of Yasuda, Agano, on the right bank of the Agano River with the Gozu Mountains behind it. Pumped from underground at 19.9°C and 105 liters per minute, the water was found in its 2024 analysis to carry 23,161 mg of dissolved matter per kilogram—a "strong brine" with salinity approaching that of seawater. Sodium makes up about 85% of the cations and chloride more than 90% of the anions. It also contains 34.1 mg of iodide and 84.6 mg of bromide, hinting at ancient seawater trapped in the strata as fossil brine, along with a generous 413.7 mg of free carbon dioxide. Nearly colorless and clear, it tastes strongly salty with a faint metallic edge. Think of it as a taciturn Sea of Japan fisherman: plain at first sight, yet its dense, briny strength wraps the body firmly and leaves a warmth that lingers long after bathing.

The Kaikake Onsen source is said to have been discovered in the Kamakura period some 700 years ago, and a travel account from 1488 already describes water welling from a rock fissure. Known as a hidden bath of the warlord Uesugi Kenshin and, in the Edo period, as an "eye spring," it was even licensed as eye drops in the Meiji era. Over 400 L/min gushes naturally, and the near-body-temperature water wraps the skin in fine bubbles, letting body and mind unwind over a long, gentle soak.
