Following my recent excursion to Beppu to enjoy the specialty onsen, I wanted to find a solution closer to home. The answer?
Yamato No Yu
This super sento is conveniently located between the Mazda (マツダ) and Delta offices, making it a prime target for Japanese businessmen finishing a long day of work.
Although it is not fed by a natural hot spring (as far as I know), this bathhouse is still quite the place to relax - rotenburo (outdoor baths), massage chairs, a full vending machine cafeteria...
This is not the place for tourists. Know your Japanese bathing etiquette, and be prepared to read plenty of kanji. If you just want a quick in-and-out, the bath costs ¥600 (the top left button on the vending machine).
This is not some small old neighborhood sento, but rather a luxurious spa-type sento that is quite the perk for those living in the area. Enjoy.
