Best Onsen Towns in Japan: 8 Hot-Spring Destinations Worth the Trip (2026)
Soaking in an onsen (natural hot spring) is one of the great pleasures of travel in Japan. This guide rounds up eight of the country's best onsen towns — from easy escapes near Tokyo to remote, snow-covered gems — with what each is famous for, how to get there, and where to book a ryokan stay.
Good to know: Most onsen are enjoyed at a ryokan (traditional inn) with a stay and dinner, though many towns have day-use public baths too. Bathing is nude and gender-separated; wash before entering. Some baths restrict guests with tattoos — check ahead or look for tattoo-friendly spots. Book ryokan early for weekends and holidays. Prices are in yen; rough US-dollar figures assume about 150 yen = $1.

Frequently asked questions
Q.Can I enter an onsen with tattoos?
It depends on the facility — even Japan's tourism agency notes policies vary widely by inn. Many places say no to the big communal bath but allow a private or in-room bath, so booking a private (family) bath is the safe option. If unsure, ask in advance (as of June 2026).
Q.Are private (family) baths available, and what do they cost?
Many inns and day-use baths have private baths, usually by reservation. Kusatsu's Otaki-no-yu, for example, charges ¥2,000 per hour for a private bath (entry fee extra, booking required). Handy if you have tattoos or are visiting as a family or couple (as of June 2026; check official site).
Q.What's the bathing etiquette? Can my towel go in the water?
Per the tourism agency: wash at the showers first and pour water over yourself before getting in (kakeyu); don't put your towel in the bath; tie up long hair; no photos or loud talking; and no swimsuits in a normal communal bath (as of June 2026).
Q.How much is a day-use bath, and are towels included?
Day-use examples (as of June 2026; check official): Kusatsu Otaki-no-yu ¥1,200 (adult), Beppu Takegawara ¥300 for a basic bath. Towels usually cost extra — some places rent them, others only sell them (as of June 2026).
Q.Is there mixed bathing or swimsuit bathing?
Normal communal baths are gender-separated and don't allow swimsuits, and mixed bathing depends on the facility. Separately, swimsuit "onsen amusement" parks such as Hakone's Yunessun exist and even allow photos (as of June 2026; check official site).
