Art Hilltop: A Mountain Sanctuary Where Nature and Art Harmonize. Nestled in a rare, high-altitude location even for Karuizawa, the architecture follows the mountain ridge in a graceful curve, inviting expansive north-to-south vistas into the living space. While the raw, untouched beauty of nature lies just beyond the glass, the interior is punctuated by artworks that capture the forest's shifting seasonal palette. Here, Italian modern design resonates with art, infusing the home with a dignified serenity and timeless beauty.
