A renowned hot spring with a history of more than 1,200 years, said to have been visited by historical figures such as Musashi Miyamoto and Masamune Date. Its gently alkaline, soft water is excellent for retaining heat. The vivid vermilion tower gate, or romon, designed by Kingo Tatsuno, the architect of Tokyo Station, is the symbol of the area, and lets visitors appreciate the beauty of traditional Japanese architecture. In recent years, the exhibitions by the world-famous art collective teamLab, held at nearby Mifuneyama Rakuen, have become explosively popular among inbound visitors, making this a one-of-a-kind hot spring destination where history, cutting-edge art, and hot springs come together.
