Tetsuya Reijō

Tetsuya Reijō [鉄有熱些 てつや・れいじょう] is a reijō (hot spring) area in Uehara, Arami Prefecture. Its name means "iron hills hot spring"; this is a reference to the geographical location of the hot springs, which lie beneath the iron-rich Iyadō Mountains. The same mountains also yield mineral hot spring water which is used in both the private hotels and public baths in Uehara's southern ward.
The springs were first discovered over 400 years ago by miners working in the nearby iron mines. The resort itself was founded in the late 1600s and became very popular at once. When iron production waned towards the end of the 1700s, use of the hot springs became the main attraction to the city of Uehara, and tourism flourished there. Several traditional wooden yoto were built along the banks of the Miyamizu River which flows through the centre of the city. There are two public bathhouses (shingyō), segregated by gender. Additionally some of the local yoto permit non-lodging guests to use their private indoor hot spring baths. 
The Tetsuya resort aims to foster a sense of stepping back in time; the center of the resort is a pedestrian-only area, and after nightfall, the bridges and streets are lit exclusively by gaslight. In the winter the area receives heavy snow. On the far side of town a 22-foot waterfall, Iromizu Falls, emerges from the mountains not far from the old mine, Toshibura Tendzuku. The resort has also seen a sharp rise in foreign tourism in recent years.
