Is this for a geology/engineering project? Gensenfuro 13
It wasn't on any tourist board website. It wasn't signposted. It existed only in the whispers of elderly sento owners and the footnotes of obscure geological surveys. Hana studied him with clear, unhurried eyes
To understand the "13," we must first understand the "Gensenfuro." In Japanese, Gensen (源泉) means "source" or "natural spring," and Furo (風呂) means "bath." Unlike a standard bathtub that simply holds hot water, a Gensenfuro system is designed to actively transform your tap water into something chemically and thermally similar to water drawn directly from a volcanic hot spring.

In many traditional Japanese inns ( ryokan ), there is no room number 13. Elevators skip the 13th floor. This is due to shini-gachi (a variation of tetraphobia), where shi (death) sounds like the number four, but 13 combines that death-adjacent feeling with the Western "unlucky 13."
The natural temperature is maintained at a steady 42°C (107.6°F), ideal for improving circulation without stressing the heart.
