I love finding these sento outside of Kansai where everything is similar but also a bit different. That is what Heiwa-yu in Kakamigahara was like. Almost the same layout as any other sento of the same size in Kansai, but just a bit different. The smoked plastic locker doors being the first big difference. This is a local sento with a good local following. Judging by their website they are very proud of the herbs they use in the rotenburo. Sadly, while I was there they had “energy drink” bath additive. It was like bathing in Lipovitan. Not a fan. The other baths and the super hot sauna with the Enka going over the speaker was awesome. I kind of wanted to start up a conversation with some of the locals but that did not happen. Good place if you ever happen to be in Kakamigahara.
