About a 10 minute walk from Oji Koen station.
At the end of the shopping arcade, right before the park/river.
An old but charming local onsen that doesn't discriminate at all against tattoos!
Expect to see some Yakuza though :)
Sauna and bath entry is only 550￥ if you bring your own towels.
Located at the end of the neighborhood shopping arcade in Oji Koen. Which means there's plenty of shops, restaraunts, cafes, and bakeries to check out before or after the onsen.
