Finding Gensenfuro 13 is a pilgrimage for the ungen (hot spring maniac). It is the final stamp in the Yumeguri-cho (hot spring stamp book). Once you have bathed in the 13th source, all other baths feel like swimming pools.

Note: As of late 2025, the Gensenfuro 13 is available in Japan, South Korea, and select European markets. North American availability requires a 240v step-down transformer and a licensed importer. Always consult a plumber before purchasing.

Kaito laughed nervously. "You have a dramatic way of putting things. Is this a local ghost story? To scare the tourists?"

While the baths are free, it is customary for visitors to leave a small donation in the boxes provided at each entrance to help with maintenance costs.

There is a particular kind of silence that only exists in the mountains before dawn. It wraps around you like cold silk, damp and expectant. And somewhere along a winding cedar-lined path, past the last vending machine and the shrine with the frayed ropes, lies Gensenfuro 13.
