OPUS Villa

A villa that allows you to experience the four seasons of Karuizawa:  “Taiyo no Mori”

This villa is situated on the eastern side of Karuizawa and offers a magnificent view in all four of the stunning and varied seasons, overlooking Mt. Hanare, and the townscape of Karuizawa town, and conveniently located just a 7-minute drive from Karuizawa Station. And only 2.6km from the nearest ski fields.

Although these accompanying photos were taken during the winter season, the scenery is adorned with fresh greenery during summer and a stunning array of golden-brown during Autumn. The songs of wild birds can be heard throughout the year, allowing you to fully enjoy and be immersed in nature.

All while benefiting from the excellent and easy access to Karuizawa Station (7mins drive), which is only about 1hr from Tokyo via the Shinkansen. Making it an ideal environment for a genuine dual-lifestyle between the city and this tranquil retreat.

The developer of OPUS Villa meticulously pursued the creation of a residence that is suitable for its location. Inheriting the essence of Karuizawa, while incorporating new ideas and technologies, this villa offers a stage where you can fully enjoy the charm of both tradition and innovation. 

The concept of this masterpiece is the fusion of nature and contemporary architecture. 


The textured entrance with natural stone flooring welcomes you through the doors which open onto a corridor with a breathtaking panoramic view, with floor-to-ceiling windows leading to an unspoilt wilderness beyond.

A fusion of nature and architecture, a symphony of beauty and design, evokes a sense of wonder and serenity.

The view from the living room encompasses a beautiful landscape, where inside sees skilfully crafted architecture, a dynamic kitchen and dining area, and an imposing wood-burning stove.

The dining room has a spacious 6-seater table, perfect for hosting guests and enjoying your meals while taking in the breathtaking view of the abundant nature of Karuizawa.

On either side of the wood-burning stove, symmetrical windows offer breathtaking views, allowing you to immerse yourself in the ever-changing seasons. 

The living room is equipped with an ideal island kitchen, perfect for spending time with close friends and family. The kitchen, made by Almilmö, a German manufacturer, is fully equipped with built-in oven and dishwasher, making it suitable not only for enjoying daily meals but also for private gatherings and parties.

The bathroom features a spacious 1624-type unit bath, where you can enjoy a relaxing time while taking in the beautiful scenery.

The master bedroom is a luxurious space, and through the large windows in this spacious room, a breathtaking panorama unfolds. 

Two further bedrooms exist, with one being a serene Japanese tatami room, a space harmonised with nature and enveloped in gentle light.


At night, OPUS Villa shines brilliantly with its illuminated sharp contours. The irregular stones, bathed in light, radiate a sparkling brilliance, serving as a symbol of the villa.
