The Onsen Route: A 7-Day Hot Spring Itinerary (Hakone to Kinosaki)
A 7-day hot-spring journey from Tokyo to Kyoto through Hakone, Kusatsu, Gero and Kinosaki — Japan’s best onsen towns, with etiquette, transport, food, what to book and where to stay.
Bathing in an onsen — a natural hot spring — is one of Japan's deepest pleasures, and a whole culture of ryokan inns, riverside baths and steaming towns has grown around it. This 7-day route is a hot-spring journey from Tokyo toward Kyoto, taking in four of Honshu's finest onsen towns. It's the most restorative way to see Japan — and the etiquette section below is essential reading before you take your first dip.

Getting around: do you need a car?
Public transport — no car needed. Every town on this route sits on a rail line, and ryokan often run free shuttle buses from the nearest station. Trains let you nap and gaze out of the window rather than watch the road — very much in the spirit of the trip. Grab an IC card for local legs.
🧳 Before You Go

Onsen etiquette (read this first)
- Wash and rinse thoroughly at the seated showers before entering the bath.
- No swimwear — you bathe nude; baths are almost always sex-segregated.
- The small towel doesn't go in the water — rest it on your head or the side.
- Tie up long hair.
- Tattoos: many onsen still refuse guests with tattoos. Look for "tattoo-friendly" baths, use cover patches, or book a room with a private (kashikiri) bath.
- No phones/cameras in bathing areas — ever.

Where to stay (hotel areas)
This route is about where you stay — the ryokan is the destination. Prioritise inns with their own quality baths (ideally a private/open-air option), half-board (dinner + breakfast), and a location you can stroll from.
Compare onsen-town ryokan →More legendary onsen towns
If you have longer or want to swap a region: Nyūtō (Akita, rustic/milky), Ginzan (Yamagata, Taisho-era, magical in snow), Kurokawa & Beppu (Kyushu), Dōgo (Shikoku, historic bathhouse).
When to go
Autumn and winter are the classic onsen seasons — steam against maples or snow. Arrive mid-afternoon to enjoy the baths before dinner, hydrate, and don't over-bathe.
