Where The Forest Becomes The Living Room

Property Highlights:

The site spans 1,538.54 sqm of freehold land, zoned residential, set well back from the road along a 6.0-metre public frontage to the southwest — a scale of landholding that, in Karuizawa’s more established districts, has become genuinely difficult to secure. Zoning restricts building coverage to 20% and floor-area ratio to 20%, and the property falls within Karuizawa’s designated townscape control zone, subject to additional sunlight regulations — safeguards that keep the surrounding forest, and the low density that defines it, protected for the long term.

The estate comprises three structures across 328.54 sqm of combined floor area: a two-storey main residence of 260.40 sqm, completed July 2004; a single-storey guest annex of 43.06 sqm, completed May 2008, operating as a fully self-contained secondary residence with its own LDK; and a reinforced-concrete garage of 25.08 sqm. The main house is arranged as 4LDK, with a walk-in closet, a dedicated storage room, two bathrooms, two washrooms, and a separate laundry room. Its living-dining room alone spans approximately 43.7 tatami mats — roughly 72 sqm — a volume of domestic space that opens directly onto the surrounding forest through full-height glazing.

The entire property underwent comprehensive renovation completed July 2025: re-painted and repaired exterior walls and ceilings, replaced flooring and wallcoverings throughout, fully renewed kitchen, bathroom, washroom, and toilet fixtures, new lighting across every room, replaced ventilation and air-intake systems, restored fittings and sashes, re-polished entrance tiling, a new video intercom system, re-coated wet areas, refinished the wooden deck, and replaced the water heater, switches, and air conditioning throughout. The property is offered move-in ready, with immediate handover.

328.54 sqm total floor area. 1,538.54 sqm of freehold land. Main house, annex, and garage. ¥358,000,000.

The Neighbourhood:

Nagakura sits within Karuizawa’s forested interior, close to the Hoshino Area — the resort district that has, for over a century, drawn visitors and residents alike for its blend of nature, gastronomy, and quiet cultural depth. At its heart is Harunire Terrace, a collection of boutique restaurants, cafés, and galleries built directly into a grove of Japanese elms along the Yukawa River — widely regarded as one of Karuizawa’s most refined dining and lifestyle destinations, and reachable within a few kilometres of the property.

Naka-Karuizawa Station, on the Shinano Railway line, is approximately 13 minutes on foot. Karuizawa Station — with direct Hokuriku Shinkansen access to Tokyo — is approximately eight minutes by car. Everyday needs are close at hand without compromising the property’s seclusion: a supermarket, a bank branch, and a convenience store all sit within a two-kilometre radius, while the forest itself remains the dominant presence around the estate.
