Katase Onsen Packages (Flight + Hotel)

This hotel is by far the best hotel I have stayed at in Japan. The rooms are amazing, the view was wonderful, and the bathrooms are excellent. With a comfortable bed, great pillows, and good AC, everything was perfect. The sauna was really good too, and the staff were super nice and helpful—they even made a map for us to find a place. This hotel is just wonderful. The buffet was amazing as well; all the food was fresh. This is a hotel I will definitely come back to. Special congrats to the staff!

as a british traveler, it was a challenge to face the language barrier however the staff at slash did a great job at fulfilling any requests. great rooms, great service, amazing breakfast!! if anyone i know plans a japan trip, i will recommend this hotel

The rooms are spacious, staff are very helpful and friendly. The hotel is closer to Shinagawa station, handy to 7-11 and other amenities

We had an amazing stay. The hotel was clean and luxurious. Bedrooms were cosy and beds super comfortable. However, although the room area was utilised well, once suitcases were there was not much space to move around. The two breakfast options were delicious (Japanese style and western buffet). The staff were extremely polite and helpful.
