Dogo Onsen No. 4 Bunyujo is a hot spring water distribution facility located in Dogo Yunomachi, Matsuyama City. A bunyujo refers to a facility that collects pumped-up hot spring source water and distributes it to various facilities such as public baths and ryokan.
The Only Bunyujo That Can Be Toured
There are four bunyujo in Dogo Onsen, but this No. 4 Bunyujo is the only one where you can view how the hot spring water is collected. The viewing room is open daily from 9:00 a.m. to 8:00 p.m., all year round (it may temporarily close for major cleaning, etc.).
Highlights
In this bunyujo, hot spring water is collected from six sources in total: four located on the premises and two located a short distance away. Inside the viewing room, you can see the hot spring water flowing from five pipes lined up in front, and check the temperature of each source on the thermometers. On the right side of the building's front, there is a hand bath where you can touch the freshly pumped hot spring source water at around 50 degrees without any temperature adjustment.
To date, 29 hot spring sources have been developed in Dogo Onsen, and 19 are currently registered as hot springs with Ehime Prefecture. The temperatures vary, with the lowest being around 20 degrees and the highest around 55 degrees, and the bunyujo adjusts the water temperature by mixing them without heating or adding water.
