A hotspring excavated
by students of Waseda University
in the summer of 1948.

An eye-catching building made of yellow plaster, in a town of hot spring where the mist of heat rises. That is Waseda Sajikiyu. Because it was excavated by students of Waseda University as they were visiting for practical training in geology and mining, it was named after them.

Inside this modern yellow plaster building, situated in an onsen town, is an atmosphere that is hard to grasp without actually visiting it. When in the hot springs of Naruko, please be sure to visit this building, too, which is reminiscent of the sulfur smoke that envelops the hot spring town.
