Living Space

The ground floor is anchored by an open-plan LDK — a living, dining, and kitchen space of a scale rarely seen in Japanese residential architecture. Floor-to-ceiling windows open the living space to the terrace and garden, creating a seamless connection between indoors and out. The double-height ceiling allows natural light to pour through the villa, creating an exceptional sense of space.

The master bedroom on the ground floor offers privacy and size, with a walk-in closet and dedicated study (DEN) attached. Upstairs, two further bedrooms and a generous guest room provide space for family or visitors. The entire upper floor is served by a sauna, bathroom, and two balconies — one on each side of the building.

Wellness & Outdoor Living

A private sauna and cold plunge bath on the upper floor offer a wellness retreat within the home. Outside, a 1,678 m² landscaped estate of flat, tree-lined land, with a terrace, a timber deck off the master bedroom, and parking for multiple vehicles with a piloti on the north side.

Lifestyle Appeal

The Minamihara area sits at the quieter, more residential edge of Karuizawa — close to the iconic Kumoba Pond, known for its breathtaking autumn foliage, as well as Harunire Terrace and the Prince Shopping Centre. The famous Matsunamiki pine avenue is nearby. Karuizawa Station — with its Hokuriku Shinkansen connection placing Tokyo just 70 minutes away — is approximately 3 km from the property. Hiking, cycling, tennis, and golf occupy the warmer months; ski resorts are within easy reach in winter. This is Karuizawa at its most liveable — spacious, serene, and well connected.
