Soak in three onsen towns and sleep in a ryokan in a single trip — start at Hakone near Tokyo, head north to Kusatsu, said to have the finest water in Japan, then finish at Ginzan, the gas-lamp street under snow that looks straight out of a painting. We lay out the route day by day, how to get there, and the bathing etiquette you'll want to know.
Picture a single trip where you soak in the onsen near Tokyo that's easiest for first-timers (Hakone), the onsen the Japanese rate as having the best water in the country (Kusatsu), and the snowy ryokan street that looks like an animated film (Ginzan) — three towns with three completely different moods. This route is built so you can soak, sleep in a ryokan, and eat kaiseki at an unhurried pace. It's for people who genuinely want to relax, not run a landmark-ticking sprint.
One thing to say straight up — the three onsen lie in different directions from Tokyo. Hakone is to the south, Kusatsu is north in Gunma, and Ginzan, the furthest, is in Yamagata up in Tohoku. Because they don't line up in a single row, we route you back through Tokyo between towns. It sounds like a detour, but it actually makes it easier to drop your luggage, switch routes, and catch your breath than dragging yourself over the mountains. This page walks you through it day by day, with real directions and the onsen etiquette worth knowing.
Start close to Tokyo (Hakone), head north to Kusatsu, then out to the furthest stop at Ginzan, looping through Tokyo as your route-change hub — travel times are approximate, so check the latest 2026 timetables before you go.

Ease in with the onsen that's easiest to reach from Tokyo. Take the Odakyu Romancecar from Shinjuku straight to Hakone-Yumoto in about 85 minutes (all seats reserved), check into your ryokan, change into a yukata, and sink into your first rotenburo to wash off the journey. Keep the first night relaxed — there's nowhere you need to rush to.

⛵ Hakone Loop2
Today you ride the classic "Hakone Loop" — a mountain train to a cablecar up to the ropeway over to Owakudani, a volcanic valley with sulphur steam billowing everywhere. Try a black egg boiled in the sulphur springs (said to add seven years to your life), then take the pirate ship across Lake Ashi, with Mount Fuji as the backdrop on a clear day. Come back and close the day with an onsen soak.

💧 Kusatsu · Gunma3
Loop back through Tokyo and head north to Kusatsu, the onsen the Japanese rate as having the best water in the country (the acidic sulphur water is so strong it's said to kill germs). The heart of town is the Yubatake, a hot-water field in the centre that steams constantly. Come evening, watch the Yumomi show, where locals stir the water cool with long wooden boards while singing folk songs.
Gunma Guide →No trains today — just wander the onsen town at an easy pace. The highlight is Sainokawara Rotenburo, Kusatsu's largest open-air bath, where you soak while gazing over a rock garden. Stop by souvenir shops through the day, try a freshly steamed manju, then head back to your ryokan for a seasonal kaiseki. This is the most relaxing night of the whole trip.

🏮 Ginzan · Yamagata5
The longest travel day, but the most rewarding. Loop through Tokyo, ride the Yamagata Shinkansen (Tsubasa) to Oishida, then transfer to a bus into Ginzan — an onsen town frozen in time since the Taisho era (the 1920s). Check into an old wooden ryokan, change into a yukata, and wait for dark, because evening is when Ginzan is at its most beautiful.
Yamagata Guide →On day 6, wander the town unhurried — stop at Shirogane Falls, 22 metres tall just behind the town (only a ~4-minute walk from the centre), soak at the public bathhouse designed by architect Kengo Kuma, then wait for dusk when the gas lamps flicker on and walk out to photograph the streamside street that looks straight out of a painting. On day 7, pack slowly and ride the shinkansen back to Tokyo to connect with your flight home.
Onsen Etiquette 101 →Straight up: these three onsen towns lie in different directions with no easy shortcut between them, so Tokyo becomes the most sensible route-change hub — every time below is approximate, so check the latest 2026 timetables before you travel.
South of Tokyo, the easiest and fastest. Take the Odakyu Romancecar from Shinjuku straight to Hakone-Yumoto in ~85 min (all seats reserved). It's a private railway, not on the JR Pass, so buy a separate ticket. Inside Hakone, the Hakone Free Pass makes the loop easy.
Kusatsu is north, the opposite way from Hakone, so you loop back to Tokyo/Ueno first, then ride the Ltd Exp Kusatsu·Shima to Naganohara-Kusatsuguchi in ~2 hrs 20 min plus a ~25-min bus (~¥710) into town — roughly 3 hours all in. This leg is on the JR Pass.
Ginzan is the furthest, in Yamagata. Loop through Tokyo once more and ride the Yamagata Shinkansen (Tsubasa) to Oishida in ~3.5 hrs plus a ~40-min bus. This leg is on the JR Pass, but Nozomi isn't (use Hikari/Sakura). If looping through wears you out, slot in one night in Tokyo.
Ever worried about how to behave in an onsen so you get it right? There are really only a few rules — learn them and you'll slip into the water with total ease. See the full version on tattoos and water types in our Onsen 101 guide.
It's immediately clear why you loop through Tokyo — Hakone is to the south, Kusatsu is north in Gunma, and Ginzan is furthest out in Yamagata, three points fanning out in different directions from your Tokyo base.
The heart of this trip is "sleeping in a ryokan" — each town has ryokan at several price levels. Browse the city guides below to compare rates and locations before you book.
