Higashiyashikizoe, Nagakura, Karuizawa-machi, Nagano

A truly exceptional opportunity to acquire a substantial landholding in one of Karuizawa’s most desirable and prestigious residential environments.

Shiozawa Estate comprises three adjoining residential plots — Lots A, B and C — offering a combined area of approximately 3,700 m² (approximately 1,119 tsubo).

In addition, the owner is offering the opportunity to acquire a further approximately 10,000 m² of private forest land together with all three residential plots in a single transaction, creating the potential for an extraordinary private estate of approximately 13,700 m² in total — subject to confirmation of the final registered areas.

This is a rare opportunity to secure an expansive private holding in Karuizawa, offering exceptional scope for the creation of a bespoke residence surrounded by extensive private natural landscape.

A Remarkable Private Estate

The three residential plots provide an unusually generous foundation for a substantial luxury residence or collection of buildings, subject to applicable planning and landscape regulations.

The combined residential land comprises:

• Lot A: 1,185.74 m² / 358.69 tsubo
• Lot B: 1,710.66 m² / 517.47 tsubo
• Lot C: 803.62 m² / 243.10 tsubo

Combined residential land: approximately 3,700.02 m² / 1,119.26 tsubo

Beyond the residential land, the additional approximately 10,000 m² of forest land offers an exceptional opportunity to create a much greater sense of privacy, seclusion and connection with nature.

For the right buyer, the combined holding could provide the foundation for a truly distinctive Karuizawa estate — with a substantial private residence set within extensive grounds and surrounded by woodland.

The Freedom to Create Something Exceptional

The scale of the combined property allows for a level of privacy and flexibility rarely available within Karuizawa.

The residential plots could potentially accommodate a carefully considered architectural project incorporating a substantial main residence, landscaped gardens, terraces and outdoor living spaces, subject to all applicable regulations.

The additional forest land further enhances the character of the holding, creating the possibility of preserving a natural woodland environment around the residential area.

Rather than simply purchasing a house, this offering provides the opportunity to create an entire private environment in Karuizawa.

Prime Naka-Karuizawa Access

Despite its peaceful and private character, the estate is conveniently positioned for access to Naka-Karuizawa and the wider Karuizawa area.

Shinano Railway’s Naka-Karuizawa Station is approximately 3 km away, around six minutes by car, providing convenient access to restaurants, cafés, shops and everyday amenities.

The location offers an attractive balance between tranquillity and accessibility — allowing residents to enjoy the natural beauty and seasonal character of Karuizawa without sacrificing convenience.

A Rare Combination of Land and Nature

Large parcels of residential land are increasingly difficult to find in established Karuizawa locations.

The opportunity to combine approximately 3,700 m² of residential land with an additional 10,000 m² of forest land is particularly unusual.

For a private buyer, family office, developer or purchaser seeking to create a landmark personal retreat, the scale of this offering provides an exceptional degree of freedom.

The forest component could provide a lasting natural backdrop to the residence, helping create the feeling of a secluded country estate while remaining only minutes from Naka-Karuizawa.

Infrastructure & Development

The residential plots benefit from existing utility infrastructure, including:

• Public water supply: Connections available on the properties
• Public sewer: Public manholes available on the properties
• Electricity: Chubu Electric Power; underground wiring permitted
• Gas: Individual propane
• Road access: Development roads of approximately 6 metres to the relevant plots

Development is subject to the applicable Karuizawa Town and Nagano Prefecture landscape and nature conservation regulations, together with other planning and environmental requirements.
