Poised at the edge of an enchanting waterlily-filled pond in Karuizawa, one of Japan’s prime resort areas, the estate of nearly 2.5 acres enjoys a pleasant mountain climate all year long. Walls of glass in the living room and the Japanese tatami room showcase the Monet-inspired pond bordered by an expansive manicured lawn and mature trees. The sleekly elegant home is highlighted by an onsen-equipped bath—a natural Japanese hot spring—that serves throughout all four seasons as the perfect end to an active day of golf, tennis, cycling, hiking, or skiing. Surrounded by serene natural beauty, the estate offers conveniently close proximity to Karuizawa’s main shopping street and train station.
