What Travellers Say
Reviews Summary
Visitors praise Yamagata Onsen Ichiryu for its unique, highly acidic sulphuric waters and the incredibly relaxing outdoor bathing experience set in a peaceful forest. The rustic charm and tattoo-friendly policy are also highlighted as positives. However, the lack of showers and the need to bring your own towel are common points of consideration.
"Really nice bath. Be aware that you need to pay for the locker and to bring or buy a towel.
Water is very acidic"
Régis Caspar
"A wonderful setting with really warm water across two pools (for the males) and separate facilities for females. The temperature varied between the two pools. The staff were friendly. The families are basic. Unfortunately, to go to the toilet, one has to exit the baths into the car park. No clothing was worn in the bathhouse."
Sanjay Patel
"Wonderful Onsen, 800¥/adult, tattoo friendly, take 1 towel and a coin of 100 for the locker. Not everything translated, just be respectful and you’ll get a great experience there. No shower."
