Karuizawa Highland Retreat: Forests, Chapels & a Hoshinoya Stay — 2 Days

A slender spring-fed pond ringed by a flat 20-minute walking path, about 20 minutes on foot from the station. In still morning air it doubles the larches and, in late October, a blaze of red and gold — the town's most-photographed reflection. Quiet, free and lovely as an easy first stretch of the legs.

Free, always open. Best light early morning or at autumn colour (late Oct-early Nov). Flat loop suitable for anyone.

The resort's historic main street, 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 freshly baked bread, and sit down for lunch — the street and its lanes hide some of the town's best casual tables.

Free to stroll; shops roughly 10:00-18:00, busiest in summer. A 15-20 min walk from the station, or a short taxi. Good for both a quick bite and provisions.

The little wooden church that effectively founded Karuizawa as a resort, built by Alexander Croft Shaw, the Anglican missionary who fell for the highland air in 1886. Still an active chapel in the trees at the top of the Old Ginza, with Shaw's old villa and a bust beside it. A five-minute, free pause that explains why the town exists.

Free; open to visitors when no service or wedding is in progress (check daily hours). At the top of the Old Karuizawa Ginza, a short uphill walk.

Hoshino's flagship resort, where villa-style rooms are scattered along a river through the woods so each feels private, with a famous hot-spring 'meditation bath' and a kaiseki kitchen built on Shinshu produce. The adjacent Harenire Terrace, a cluster of riverside restaurants and shops on a wooden boardwalk, is your easy dinner option. The benchmark for a Japanese highland retreat.

Roughly ¥60,000-120,000+ per night, highly seasonal (2026 approx.). Books well ahead for summer and autumn colour. Free shuttle from Karuizawa Station; Harenire Terrace is a 2-minute walk for dinner.

An astonishing organic-architecture chapel in the Hoshino woods — arcing ribs of stone and glass that the architect conceived as 'a church of stone and light and water', honouring the Meiji Christian thinker Uchimura Kanzo. Inside, the curves and a thread of running water make a space unlike any other church in Japan. Quietly moving, and free to visit between weddings.

Free; viewing when no wedding is in progress (check hours). In the Hoshino Area near Hoshinoya, an easy walk or shuttle. Pair with the adjacent High Note chapel grounds.

Not a single plunge but a 70-metre-wide curtain of countless fine threads — spring water filtered through the volcano seeping straight out of a curved rock face into a shallow pool. Cool, even, and luminous, fed not by a river but by groundwater, so it runs clear year-round. A short, flat path leads in from the road north of town.

Free. About 20 min by car or bus north of Karuizawa Station; short level walk from the lot. Best on a bright day for the glow; can be busy midday in summer.

A long-loved Italian kitchen in the Old Karuizawa quarter, working highland vegetables into fresh pastas and iron-plate pizzas — the kind of unfussy, reliably excellent table the town is quietly known for. A relaxed final meal before the bullet train carries you back to the city in just over an hour.

No reservations — walk in (short waits at weekends). Old Karuizawa, near the Kumoba area. Relaxed pricing (2026); a fine, unhurried send-off.
