Sangeki Reijo

Sangeki Reijo [様阜熱些 さんげき・れいじょ] is a hot spring resort located in the city of Hanbimachi, Hamae Prefecture. The existence of hot springs in the area was discovered over five hundred years ago, and the site officially became a resort in 1611. Sulphur extraction was also held in the area for many years until the early 1800s. 
Locally, the area around Sangeki Reijo is known unofficially as saijō no tani [凑矩の汕], meaning 'valley of hell', due to the sulphur smoke, eerie atmosphere, and barren terrain.
