Joban Yumoto [Hot Spring] - Joban Yumoto

Japanese: 常磐湯本[温泉] - じょうばんゆもと

A hot spring in Tokiwayumotocho, Iwaki City, Fukushima Prefecture. Salt spring, 58°C. Long known as Sahako no Yu, it was the only post station on the Iwaki Kaido road with a hot spring during the Edo period. This hot spring is considered non-volcanic, and springs out from the granite rocks under the Tokiwa coalfield along a fault line. In the mid-Meiji period, it gushed forth from over 50 sources. After successful eruptions from drilling, excessive digging was carried out, and the amount of water flowing out decreased. As the development of the Tokiwa coalfield progressed, the nearby coal mines flooded one after another, lowering the hot spring surface. After the end of the Taisho period, it became impossible to pump the water, and many inns went out of business.

福島県いわき市常磐湯本町にある温泉。食塩泉，58℃。三函（さはこ）の湯として古くから知られ，江戸時代は岩城街道唯一の温泉のある宿駅であった。この温泉は非火山性とされ，常磐炭田下の花コウ岩から断層線に沿って湧出し，明治中ごろには50ヵ所余りの源泉から自噴していた。その後ボーリングで噴湯に成功してから乱掘が行われ，湧出量は減少した。また常磐炭田の開発が進むとともに付近の炭鉱の出水が相ついで，温泉面が低下し，大正末以降はポンプによる揚げ湯も不可能となって旅館の廃業が続出した。
