Things to Do in Karuizawa: A 2026 Highland Guide

Karuizawa has been where Tokyo goes to breathe since a Canadian missionary fell for its summer cool in the 1880s. The result is a highland town at 1,000 metres on a volcano’s skirt — larch forests, mirror ponds, modernist chapels and a peculiar density of fine restaurants for its size — and it sits barely 70 minutes from Tokyo by bullet train. That combination makes it the easiest luxury reset in Japan. Here’s what to do, where to eat and sleep, and how to plan a calm two days in 2026.

Why Karuizawa

Most Japanese resorts make you choose between nature and comfort. Karuizawa gives you both within a few kilometres: forest walks and a curtain waterfall on one side, antique shopping and excellent French and Italian kitchens on the other, all at an altitude that stays cool when Tokyo swelters. It’s flat enough to cycle, refined without being stuffy, and close enough that you can leave the city after breakfast and be walking in the larches by lunch. Our Karuizawa highland retreat lays out a gentle two-day version.

The forest chapels

Karuizawa’s strangest charm is its chapels, two of which are small masterpieces. The Stone Church (Uchimura Kanzo Memorial), in the Hoshino woods, is an organic-architecture chapel of arcing stone-and-glass ribs that the architect conceived as “a church of stone and light and water” — inside, the curves and a thread of running water make a space unlike any other church in Japan. Nearby, the dark-timber High Note Chapel glows by lamplight.

Up at the top of the Old Ginza stands the Shaw Memorial Chapel, the little wooden church that effectively founded the resort, built by Alexander Croft Shaw, the missionary who started it all in 1886. All are free to look around when no wedding or service is on. Note that the historic Mikasa Hotel, often listed in older guides, is closed for multi-year restoration and cannot be visited in 2026 — don’t plan around it.

Water and forest

Kumoba Pond is the town’s signature reflection: a slender spring-fed pond ringed by a flat 20-minute path, about 20 minutes’ walk from the station, that doubles the larches in still morning air and blazes red and gold in late October. North of town, Shiraito Falls is a 70-metre-wide curtain of countless fine threads — not a river but volcano-filtered groundwater seeping straight out of a curved rock face, so it runs clear and cool year-round. A short flat path leads in from the road. Both are free, and both reward an early start before the day crowds arrive.

Shopping and eating

The historic Old Karuizawa Ginza is a pedestrian run of jam shops, bakeries, coffee roasters and antique dealers that have served summering Tokyoites for over a century — pick up Karuizawa’s famous fruit jam and fresh bread. For outlet shopping, the large Karuizawa Prince Shopping Plaza sits right at the station.

The town is quietly known for its kitchens. Karuizawa drew the Meiji elite and their cooks, and the legacy is a strong French and Italian scene. Trattoria Primo in the old quarter is a long-loved Italian table working highland vegetables into fresh pastas and iron-plate pizzas (no reservations — walk in). For a special meal, the dining at Hoshinoya and the area’s French restaurants are worth the booking.

Getting there and around

Karuizawa is one of the easiest places in Japan to reach. The Hokuriku Shinkansen runs from Tokyo Station to Karuizawa in about 70 minutes, and trains are frequent enough that you don’t need to plan tightly. From Nagano City it’s roughly 30 minutes the other way, which makes Karuizawa a natural first or last stop on a wider Nagano loop.

Once there, the town center, Kumoba Pond and the Old Ginza are walkable or a short cycle — rental bikes are everywhere near the station and the plateau is flat and well-marked for cycling, which is how many regulars get about in summer. Shuttle buses serve the Hoshino Area and its chapels. For outlying sights like Shiraito Falls, use the local bus or a taxi. A rental car only earns its keep if you plan to range further across the Asama plateau or combine Karuizawa with the onsen towns beyond. Because it’s so well connected, Karuizawa pairs cleanly with a city trip: leave Tokyo after breakfast, walk in the larches by lunch, and you’ve lost almost no time to transit.

A little history

Karuizawa was a humble Nakasendo post town until Alexander Croft Shaw, an Anglican missionary, began summering here in 1886 and championed its cool, dry highland air as a remedy for Tokyo’s heat. Wealthy Japanese and the foreign community followed, building villas, churches and tennis courts, and the resort culture that still defines the town took root. That heritage is why Karuizawa feels different from a typical onsen resort — it’s a garden suburb in the forest, shaped by a century of people who came specifically to slow down.

Where to stay

The flagship is Hoshinoya Karuizawa, where villa rooms scatter along a river through the woods so each feels private, with a famous “meditation” hot-spring bath and a Shinshu kaiseki kitchen (roughly ¥60,000-120,000-plus per night, highly seasonal, 2026 approx.). The adjacent Harenire Terrace, a boardwalk cluster of riverside restaurants and shops, is the easy dinner option. Around it sit excellent design hotels and the Prince complex by the station. For how Karuizawa compares with the prefecture’s other bases, see our Nagano accommodation guide.

When to go

Summer (July–August) is the classic season, when Tokyoites flee the heat and the town hums — cool, green and busy. Late October to early November is arguably better: the foliage around Kumoba Pond and through the larches is spectacular and the crowds are thinner on weekdays. Winter is quiet and cold with occasional snow; spring brings fresh green and the chapels at their most serene. The international departure tax rises from ¥1,000 to ¥3,000 from July 1, 2026, included in airfare — a small budgeting note.

FAQ

Is Karuizawa worth visiting as a day trip from Tokyo? Yes — at about 70 minutes by shinkansen, a day trip easily covers Kumoba Pond, the Old Ginza and a chapel or two. But the town is loveliest early and late, after day crowds thin, so one night turns it from a sightseeing stop into a proper retreat.

What is Karuizawa famous for? Cool highland air, forest chapels, larch and lava landscapes, antique and jam shopping along the Old Ginza, and a strong French and Italian dining scene — all at 1,000 metres an easy train ride from Tokyo. It’s been Japan’s premier summer resort for well over a century.

How many days do you need in Karuizawa? Two days and one night is the sweet spot for couples: a pond, the old street and a chapel on day one, a forest church, the falls and a long lunch on day two. Add a night if you want to cycle the wider plateau or play golf.

Can you get around Karuizawa without a car? Mostly, yes. The town center, Kumoba Pond and the Old Ginza are walkable or a short cycle, and shuttles serve the Hoshino area. For Shiraito Falls and outlying spots, use the local bus or a taxi — a rental car helps only if you’re ranging further across the plateau.

Is the Mikasa Hotel open to visit? No. The historic Former Mikasa Hotel is closed for multi-year seismic restoration and is not visitable in 2026. For Western-heritage Karuizawa, see the Shaw Memorial Chapel and the Old Ginza instead.
