Visiting Hoshi Onsen Chojukan as an American was quite different from other experiences I had in Japan. Soaking in the baths twice a day was peaceful and beneficial. The meals served in the dining room were outstanding as well. Tattoos did not seem to be a problem in the baths. I eat a lot but it became difficult to finish the meals with so many different foods available on offer. The service was friendly and responsive, the hotel is well staffed in regards to how many guests it receives. The surrounding area is incredibly beautiful in summertime, and there are many fun areas and activities for tourists. The wifi and the phone signal are poor, which helps with disconnection and relaxation. My mind felt very quiet after staying here for three days.

The onsen access schedule prevents men from taking a regular shower-- anywhere in the hotel-- between 7am and 3pm.

Beautiful, scenic, and historic onsen ryokan hotel nestled in the mountains. The ryokan retains an authentic and genuine atmosphere. Meals are lovely too, and prepared with care and attention to detail. There are beautiful hikes around the property too, and the three onsen facilities are absolutely stunning!

The property is perfect.

This place is right out of a fairytale. It is serene, beautiful and very decadent. The onsens were absolutely beautiful, the food delicious and the staff very helpful.

I can’t fault anything

The location is beautiful, the room was extremely relaxing, the baths and food were amazing. A person speaking English well seemed to have been responsible for me, and I felt comfortable asking him all of my questions, as this was my first experience of anything similar. I could use the baths although I have large tattoos. Could get there completely by public transport - although note that one of the buses runs on a different schedule than what google maps believes. The baths are not very large, so perhaps one should read beforehand on the expected behavior.

As the place is old, a large spider appeared at some point in the room, but that seems inevitable.

The authenticity, and the beauty of the hot springs/bath houses.

Everyone was very nice, but I wish the staff spoke better English. Also, a proper explanation about the hot spring etiquette would have been nice

It was so beautiful! It is a bit remote, but thats exactly what we liked about it! It lies in a nice valley, that in december was a bit snowy. Ofcourse, the very traditional building was so sophisticated and beautiful, but even though it felt such high end (and it is!), we felt comfortable there. It was easy to relax, the Onsen are amazing and beautiful. Very kind staff as well, they spoke english. The food was exceptional as well. One of us was vegetarian, we let them know beforehand and it was no problem. Would recommend at least 2 night stays. The price for the value you get is exceptional.

This is the nicest developed hot spring I have been to anywhere in the world.

Nothing, absolutely perfect.

The onsen areas with warm water are wonderfull, so relaxing and the atmosfere is beautiful. Enjoy the warm water while looking at the sorrounding nature and mountain is a unforgetable experience. the dinner was very well organised and with lots of japanese deliciuos food. The breakfast could be a little too rich for a European citisens but also good. The employees are welcoming and they are really caring about the guests. It is worth the 2 buses rides to get here :)

The location was excellent - deep in the mountains of Gunma. I chose this onsen because I wanted to stay in a remote location off the beaten path. The ambiance of the inn is incredible, and the baths are exceptional. This inn felt like a functioning inn from the past - it is rustic, shows signs of wear, and was cold inside in winter due to lack of insulation. It felt like an authentic inn from the past. That said, these rustic qualities are not for everyone.

My room was more rustic than I expected. The doors to the rooms are shoji sliding doors made of paper. They provide absolutely zero noise insulation between the rooms and the hallway, and the guests in neighboring rooms. This means you can hear your neighbors coughing, farting, snoring, etc. The walls are also very thin. This means that you may be disturbed if your neighbors are not respectful. Luckily my Japanese neighbors were respectful and quiet. My room showed signs of wear. The tatami hadn't been replaced in some time and the walls were scuffed and showed signs of wear. Do not book this inn if you expect a luxurious ryokan experience.

Great stay, fantastic onsen, good food, comfortable sleep

The walls are very thin, could here people in other rooms talking, TV, mobile phone
