forumWhat families say

Rakuten Travel rating 4.69 out of 5 (273 reviews). This Japanese-style ryokan, decorated with pressed-flower artwork, is about a 1-minute walk from the Yubatake, Kusatsu Onsen's largest attraction. Guests praise above all the private-hire bath that comes with every room. The ryokan draws on two sources, the Yubatake source and the Shirahata source, which is rare even in Kusatsu, so guests can try different spring waters within the building. Restaurants and a convenience store around the Yubatake are close at hand, which makes sightseeing with children easy.

Overview

Kusatsu Onsen Masunariya Ryokan is a three-story wooden Japanese-style ryokan a 1-minute walk from the Yubatake hot-water field, a well-known sightseeing spot in Kusatsu Onsen. Each of its 6 rooms comes with its own private-hire bath, so families can enjoy the onsen on their own without watching the clock or thinking about the people around them. Dinner is served in a private room, and staff come and go only rarely, so families with children can relax over the meal. Please note that there is no elevator and that food allergies cannot be accommodated.

Rooms

There are 6 rooms in total, laid out so that no room adjoins another. Two types are available: 10-tatami Japanese-style tatami rooms for 2 guests, and Japanese-style tatami rooms of 12 tatami mats or more for 2 to 4 guests. Guests cannot choose which room they are given. Every room has an air purifier with a humidifying function. The rooms do not have their own bath; the private-hire bath assigned to each room is located away from the room, and guests are given a key for it. All rooms are non-smoking, and there is a smoking room in the building. Accommodation plans include children's rates.

Dining

Dinner is served in a private room, so you never share a table with other guests. All the dishes are served at once, so staff do not come in and out of the room again and again, and you can eat at your own pace. Breakfast is served in the banquet room on the first or third floor. The dining areas were renovated in April 2025, and one example of a dinner dish is Joshu beef sukiyaki. Please note that the ryokan cannot change dishes or remove ingredients for allergies or personal preferences.

Baths and Private-Hire Baths

There is one communal bath each for men and women, fed by the Shirahata no Yu source. With cypress tubs and a cypress changing area, they let you enjoy the milky-white water regarded as the finest in Kusatsu Onsen. In addition, there are 6 private-hire baths, matching the number of rooms, drawn from two spring sources: 4 from the Yubatake source (tiled) and 2 from the Shirahata source (cypress). Each private-hire bath comes as a set with a room, and you are given its own key from check-in until checkout, so your family can bathe whenever you like on your own. They are not open-air baths. The changing areas have benches and handrails.

Family-friendly notes

The ryokan is a three-story wooden building with no elevator or similar facilities. Stairs are involved in getting around, so take care if you have a stroller or a lot of luggage. Guest rooms have Western-style toilets with a washing function. The changing areas of the private-hire baths have benches and handrails, arranged to make getting in and out of the tub easier. The ryokan values a quiet atmosphere and does not offer mahjong, karaoke or similar entertainment. Food allergies also cannot be accommodated, so please take care if your child has an allergy.
