Inari‑yu (稲荷湯) Traditional Sento
Inari-yu is a historic sentō in Kita, Tokyo, built in 1930 with traditional architecture. Because of its classic style, visiting this sentō is not only relaxing but also culturally enriching for kids and adults. It’s a good fit if your family wants a more “local” bathhouse experience, one that feels authentic and timeless.
Manyo Club / Toyosu (Family‑Reserve Baths)
At Manyo Club in Toyosu, families can reserve private or “family” baths, which means the whole group can soak together. The facility also features rooftop foot baths, lounges, and kid‑friendly spaces, making it both relaxing and fun for groups. According to visitors, it’s a very comfortable and social place, especially for families who want some privacy.
Yūen Bettei Daita (由縁別邸 代田) / SOJYU Spa
This spa has a calm, upscale feel and provides a “mini-resort” atmosphere in Tokyo. The hot spring water comes from a source similar to that of Hakone, giving a more authentic onsen feel even within the city. It’s perfect for families or groups looking for a slightly more luxurious, relaxing day trip without leaving Tokyo.
Tips for Families Visiting Onsen in Tokyo
- Check for reservation or family‑bath options: If you’re with a big group, a reservable bath (kashikiri) can make the experience much more relaxing.
- Bring or rent towels and clothes: Some spas provide yukata or robes, but plan ahead.
- Be aware of bathing etiquette: Always wash before entering the bath, and talk to your kids about onsen manners.
