Liked: Cleanliness, property conditions & facilities
Very comfortable ample sized room. The staff were amazing without exception. Great Onsen. Had read comments that it could be noisy because of the wooden construction but this was not the case for us. I also liked being able to open the window in our room because of Japanese accommodation tendency for super heating during winter. I loved Kusatsu, and would definitely stay at Kusatsu Onsen Gensen Ichinoyu again.

Good Location

The location is good, within walking distance to city center Staff is very polite. The room is spacious. Breakfast is simple. The onsen does not have an elevator, so it's a bit difficult to carry the luggage up the stairs. Overall, it was a good stay.

Liked: Cleanliness, staff & service, property conditions & facilities
The staff were very friendly. The hotel was amazing. Loved having an Onsen in the hotel and a Footbath outside the lounge area. A couple of minutes walk to the Yubatake, restaurants and 711. I would recommend going to the supermarket or Lawsons near the bus station. Much quieter and more stock than the 711. There are no cooking utensils or plates and cutlery in the room but see the reception staff and they will give them to you. The Yubatake and surrounding area look amazing lit up at night. Loved our stay here

Amazing Experience

The place is close to the bus station and merely a block away from Yubatake. It's really clean and modern yet still have old school ryokan vibe. Free foot bath right at the lobby. Staff is polite and professional, speaks passable English which is better than my broken Japanese. We had a private onsen tub in the room and it's absolutely amazing. We could go soak in the tub whenever we like for however long time. Free breakfast were simple western bites but we ain't there for that. Highly recommended for solo, couple or family trip.

Staff are extremely helpful & friendly, but I guess it's Japan's culture, rules can't bend a bit to accommodate clients needs. I missed breakfast coz of my very early departure & no boxed BF is allowed.

The property’s website did not have exact map to get there. I asked at the info center for direction but a couple from Hong Kong took 1 hour to locate the property. It was not mentioned there are long stairs to get there from “yubatake” tour spot. No elevators at the property you have to lug your suitcases up to your room.

Very closed to the bus station, which was about 5 mins walk. The hotel is building with old architecture, but with modern updates. It was an easy check-in process. Our room was really nice and spacious. The room was clean, but my blank had a small stain on the blanket. The wifi is really good. There is a public onsen on the lower floor for guests to enjoy. We reserved a 45 mins private onsen for 3200 yen. It was well worth it! The room was roomy and clean. It has a private shower and bathroom. The we enjoyed our private onsen. Very relaxing. Highly recommend. Some tips. Don't walk in the hotel with your shoes or sneakers. There are sandals that you can walk outside the streets with. It's located in the lockers with the keys when you entered the hotel. If you want to walk around the hotel you can walk with your socks or the staff can you give a sandals. Breakfast is a buffet. Limited selections, and you have to make a time slot rsvp. They bar closed around 10pm. We loved our one night stayed. We would come back again!
