About Koro-kan
Koro-kan, written 月光園 鴻朧館 in Japanese, is a ryokan in Arima, about 0.5 km in a straight line from Arima Onsen Station. Below we've pulled together what its own website says about private bathing: in-room baths, private family baths, the water and the tattoo rules.
Rooms with their own open-air bath are offered, but the website doesn't say every room has one, so pick the room type carefully when you book. There are 3 private (kashikiri) baths that one group at a time can lock and use, and the website lists a charge (¥47,300). The website doesn't explain how slots work, so ask at check-in.
The property describes its water as free-flowing (源泉かけ流し), fed from the source rather than recirculated, although it also notes that some baths are heated. The website doesn't state a tattoo policy. If that matters to you, email the property before booking. Some plans include dinner served in your room.
Anything marked 'not confirmed' below, such as tattoo rules for private baths, wasn't stated on the pages we checked. That doesn't mean the answer is no, only that we haven't assumed one. We checked the official website on 17 October 2026. Rules and fees change, so confirm with the property, and use the buttons above to compare the same room across booking sites, including taxes and cancellation terms.
