Japan’s Best Onsen Towns: Where to Soak and Stay
Japan has over 27,000 hot spring sources and some 3,000 onsen resorts (onsen chi). Whether you want a sleepy mountain village with steam rising through wooden streets, a sophisticated resort town with world-class ryokan, or a coastal town where volcanic springs meet the sea, Japan has an onsen destination for every traveler. This guide covers the most acclaimed and accessible onsen towns across the country.
Hakone (Kanagawa) — Near Tokyo
Japan’s most popular onsen getaway from Tokyo. Hakone is a volcanic caldera area with numerous hot spring types across six distinct onsen zones. Mt Fuji views, the Open Air Museum, Hakone Ropeway over sulphurous Owakudani, and Lake Ashi boat rides make Hakone a multi-activity destination beyond just bathing.
- Spring type: Sodium chloride, sulphur-bearing, and other types depending on the area (Miyanoshita, Gora, Kowakidani, Sengoku, Dogashima, Yumoto).
- Getting there: Odakyu Romancecar from Shinjuku (1 hour 30 min, around JPY 2,500); or JR Tokaido line to Odawara then Hakone Tozan Railway.
- Top ryokan: Gora Kadan, Hakone Ginyu, Ryuguden, Tenzan Tohji-Kyo (public bath complex for day trippers).
Kusatsu (Gunma)
Many Japanese poll this as the country’s number one onsen. Kusatsu’s Yubatake (hot spring field) produces an extraordinary 32,000 litres of extremely acidic water per minute in the center of town. The town has a famous yumomi wooden paddle ritual to cool the water. Excellent for skin conditions; not suitable for sensitive skin.
- Spring type: Strongly acidic (pH 2) sulphurous water. Known for high mineral content.
- Getting there: JR Naganohara-Kusatsu-guchi Station + bus (25 min). Or direct buses from Tokyo (about 4 hours).
- Highlight: Netsu-no-Yu free performance of yumomi (paddle-cooling ceremony); Sainokawara outdoor rotenburo (free).
Kinosaki Onsen (Hyogo)
A perfectly preserved onsen town with willow-lined canals and seven public bathhouses (sotoyu) that guests tour with their yukata and wooden geta sandals. The ritual is to stay at a ryokan and bathe in all seven bathhouses in an evening. One of Japan’s most charming onsen experiences.
- Spring type: Sodium chloride with a soft, gentle quality.
- Getting there: JR Toyooka line from Kyoto (2 hours 10 min, Konotori limited express).
- Best season: Winter (November-February) for crab season (Matsuba crab from the Sea of Japan); cherry blossom in early April.
Beppu (Oita, Kyushu)
Beppu is the undisputed onsen capital of Japan in sheer volume — 100 million litres of water from 2,800 springs per day. The famous Hell Tour (Jigoku Meguri) visits 7 boiling, coloured spring pools including the blood-red Umi Jigoku and the cobalt blue Umi Jigoku. A unique and slightly surreal experience.
- Spring types: Multiple — sodium chloride, sulphur, carbonated, radium, iron-bearing, depending on zone.
- Getting there: Beppu Station (Sonic limited express from Hakata/Fukuoka, 2 hours).
- Highlight: Suginoi Hotel’s Aqua Garden outdoor pools with sea views; Takegawara public sand bath.
Yufuin (Oita, Kyushu)
A quieter, more sophisticated alternative to Beppu. Yufuin sits in a misty valley with Mt Yufu as a backdrop, and has a charming walking street with artisan shops, cafe-galleries, and small museums. The town is known for couples’ travel and upscale ryokan with private outdoor baths.
- Getting there: Yufuin Station (Yufuin no Mori scenic train from Hakata, 2 hours — one of Japan’s most scenic rail journeys).
Ginzan Onsen (Yamagata, Tohoku)
One of Japan’s most beautiful onsen towns. Gas lanterns illuminate a river canyon lined with three-story Taisho-era wooden buildings at night. The atmosphere — especially in snowfall — is dreamlike. A small number of ryokan along the single main road make this an intimate experience.
- Getting there: Oishida Station (Yamagata Shinkansen from Tokyo, 2.5 hours) + bus (35 min) or taxi.
- Fujiya ryokan: The most famous property in the village; a luxury renovation of a century-old building. Demand vastly exceeds supply — book 6-12 months ahead.
Nozawa Onsen (Nagano)
A traditional ski-and-onsen village with 13 free public baths (sotoyu) open to all. The baths are genuinely hot (some over 60C — dip cautiously) and authentically used by local residents. The village maintains an old-fashioned mountain atmosphere year-round; ski season is December to March.
- Getting there: Iiyama Station (Hokuriku Shinkansen from Tokyo, 1 hour 50 min) + bus (30 min).
Noboribetsu (Hokkaido)
Hokkaido’s most famous onsen resort, set in a volcanic valley called Jigokudani (Hell Valley). Nine different spring types from a single source area. Large resort hotels with extensive indoor bath facilities. Especially popular in winter when steam rises dramatically above the snow.
- Getting there: Noboribetsu Station (JR Muroran line from Sapporo, 1 hour 20 min) + bus (13 min).
Tips for Visiting Onsen Towns
- Most public bathhouses and ryokan onsen require full nudity in the water. Tattoos are still prohibited at many facilities; check the policy before visiting if relevant.
- Rinse off at the shower station before entering the communal bath. This is mandatory etiquette.
- For outdoor rotenburo (outdoor baths), a small towel can be folded on your head but must not enter the water.
- Onsen towns are best visited mid-week to avoid weekend crowds. Peak seasons (cherry blossom, Golden Week, autumn foliage, New Year) require very early booking at popular ryokan.
- Day-trip bathing (higaeri onsen) is widely available at most onsen towns for travelers not staying overnight.
