Tamatsukuri Onsen is among the oldest in recorded history in Japan. Located on the Tamayu River near Lake Shinji it has numerous ryokan and guest houses as well as many large resort style hotels.
In the river itself are several small pools that can be used for free and the main street also has a free foot bath, but the town had no public onsen until 1996.
The architecvt chosen to design the new public onsen was local boy Shin Takamatsu.
His design is ditinctive and uses one of his trademarks, geometric solids.
