A simple weakly-radioactive spring rising in Arima, carrying enough radon (137 Bq/kg) to fall within the radon-spring tradition. The water is colorless and transparent but develops a yellow-brown sediment if left to stand for a long time. As a cold-mineral source of 22.0 °C, it is reheated for bathing and disinfected with a chlorine-based agent. The posted indications cover neuralgia, muscle pain, joint pain and similar chronic complaints.

About

The indoor bath at Maple Arima runs on the hotel's own spring, registered as Hoju sengen (豐壽泉源), one of Arima's silver-spring (ginsen) waters. There's no open-air bath, but the bathing area has utaseyu (打たせ湯, a standing bath where water beats down from overhead), a jet bath, and a far-infrared sauna. Reviewers describe the water as warming right through to the core. It's a casual, everyday sort of hotel rather than a formal ryokan, with a restaurant, a bar lounge and a karaoke room, and it's just as easy to visit solo as with kids.

341. Maple Arima, Arima Onsen I went for a higaeri for 1300 (listed as 09:00 to 11:00 and 13:00 to 21:00). An onsen with Showa-era vibes, no rotenburo, and only clear water. The bath photos online matched what was there. All the baths are in the indoor area, so it is easy to breathe. While I was there, staff came by to collect water samples from all the baths. 1. Main large bath with clear water and a bubble area. Temperature 42. 2. Round jet bath with clear water. Temperature 38. 3. Area with three utaseyu. 4. Shallow walking bath with two zones. 5. Area for lying down. The water is only clear, and the onsen itself is quite utilitarian. There is not much reason to go to this onsen when visiting Arima. 05.01.2025
