What Travellers Say
Reviews Summary
Visitors praise Zao Onsen Oyu Public Bath for its authentic, no-frills experience and incredibly hot, natural spring water. The low 200 Yen entry fee and the honor system are highlighted as unique positives. However, the intense heat and lack of showers are noted as potential challenges for some.
"Very clean public bath. You just need to pay 200Y to enter. There are shelving for bag storage while you having your bath. It is visible from the onsen so no problem with no locker. No shower facility just rinse with onsen water. The temperature of this onsen is the hottest among the rest. I barely can enter. It was better after several attempts.. I was the only one at the onsen on a Friday afternoon. Outside there is a free footbath. But compare to the temperature inside, I just felt the footbath is not hot at all.. 😁"

"Simple public Bath ¥200. Has a sink but no shower - you need to bail out the Onsen water to rinse off before getting in"

"Very basic.
Just shoe storage, clothing shelves and a small pool. It is unmanned, you just put 200 Yen in the bin before you go in."
