The Tsuruno-yu hot spring was sunk in the reservoir (Okutama lake). But it was reconstructed on the lakeside before that time. The writers found the spring source by the invesitgative tunnel on the left reach of the Tama river, and the hot spring was gathered by the boring (44 holes) in that tunnel. The temperature of this spring is 31.2°C, and its flow is 320 l/mim. On the other hand, it was connected between the lakeside and the boring points with the humepipe which is set in the tunnel and the vertical shaft. The hot spring was carried in the humepipe to the vertical shaft, and after then it pumped up to lakeside by the submersible-motor pump. It is closely related to the level of hot spring (A) in the vertical shaft and the water level of reservoir (B). Always, the level of hot spring is higher than the water level of reservoir. As the ascent of the descent of the water level of reservoir, the level of hot spring become of the same conditions too. As the ascent of the water level of reservoir, it decreases the value of A-B, and on the contray, as the descent of the water level of reservoir, it increases the value of A-B.
