Kusatsu Onsen
Kusatsu Onsen Family Hotels: Yubatake, Private Baths, In-Room Dining
One of Japan's most celebrated hot springs — relax as a family with private-hire baths and in-room dining
When choosing a hotel in Kusatsu Onsen with kids, many families wonder whether they can bathe without worry at such a celebrated hot spring while traveling with young children. Kusatsu Onsen is one of Japan's top hot springs by natural hot water output, with hotels clustered around its famous Yubatake (hot water field). Sitting at an elevation of 1,200 meters, it stays cool in summer, which is a welcome bonus for a family trip escaping the heat.
A reassuring point for an onsen trip with kids is how many hotels here let you bathe without worrying about other guests. Of the 14 Kusatsu Onsen hotels listed on this site, 10 have a private-hire bath for the family alone (4 of which are free of charge), and 7 have a bath in the room. Even babies and small children who aren't ready for the communal bath can enjoy a relaxed soak in a space that's just for your family. Many hotels here have gentle simple-alkaline hot spring water, and 3 have a large communal bath.
Meals and facilities show thoughtful attention to families too. 13 hotels have a Japanese-style tatami room that's easy for futon co-sleeping, and 2 offer in-room dining, so you can eat without feeling self-conscious even if your child gets fussy. Two hotels can accommodate toddler meals, 0 offer a buffet kids love, and 5 can accommodate food allergies. Some hotels also hold Welcome Baby certification, recognizing how well they support families with young children, and others offer crib and baby bath rentals, which is reassuring even with a very young baby.
Beyond a stroll around the iconic Yubatake or Sai-no-Kawara Park, Kusatsu also has spots kids can enjoy, such as Kusatsu Tropical Land, where you can get close to animals. A ski resort is nearby in winter too, so there's fun to be had by visiting in a different season. Since it stays cool even in summer thanks to its elevation, it's also a great area for an onsen trip that doubles as an escape from the heat.

Travel tips
Kusatsu Onsen is mainly reached by bus from JR Naganoharakusatsuguchi Station, or by car. You can also drive in from the Karuizawa area. Because of the elevation, mornings and evenings stay cool even in summer, so it's reassuring to bring something to layer on. Winter brings snow and icy roads, so studless winter tires and cold-weather preparation are a must if you're driving. Around Yubatake there are hills and stairs, so a baby carrier can sometimes get around more easily than a stroller. The hot spring water here is on the strong side, so it's reassuring to keep young children's bathing time short and have them drink water often.
Best season
Summer is ideal for escaping the heat thanks to the elevation, making it a great season for a family trip. Early summer's fresh greenery and autumn's fall foliage are beautiful too, and winter brings skiing and the pleasure of soaking in the onsen while watching the snow. Winter requires care for the cold and icy roads, but the combination of snow and a famous hot spring is part of Kusatsu's unique charm. The onsen town has its own atmosphere to enjoy year-round.
Getting there
About 25 minutes by bus from JR Naganoharakusatsuguchi Station on the Agatsuma Line. By car, via the Kanetsu Expressway and Joshin-etsu Expressway. It's also accessible by car from the Karuizawa area, and the onsen town itself is easy to explore on foot.
