Odawara Art Foundation – Enoura Observatory
Perched against the Hakone Mountains with sweeping views over Sagami Bay, the Enoura Observatory is an extraordinary convergence of art, architecture, and Japanese cultural heritage. Conceived by renowned artist Hiroshi Sugimoto, this contemplative space transcends historical periods and artistic genres, offering visitors an immersive experience where nature, light, and materiality converge.

A retreat from the energy of Tokyo, the observatory unfolds across a carefully orchestrated sequence of structures, sculptures, and gardens—each positioned with a deep awareness of seasonal rhythms and spatial harmony. The observatory’s observation platforms align with celestial events: a glass-encased steel tunnel frames the winter solstice sunrise, symbolizing renewal, while another platform captures the summer solstice sunrise, embodying the cyclical flow of time.

Sugimoto’s reverence for history and craftsmanship is evident in the garden’s composition, where ancient stones—painstakingly collected over decades—are arranged in accordance with his personal interpretation of Tachibana’s seminal principles of Japanese garden design.
““When setting up stones for a garden, you must first be aware of the basic concepts. In consequence, the horizontal placement of stones is my core principle in laying out the garden.””
Hiroshi Sugimoto
Beyond its architectural mastery, the Enoura Observatory offers breathtaking vistas, meandering forested pathways, and a seamless integration of historic and contemporary elements. To preserve its meditative atmosphere, visitation is limited to timed appointments, ensuring each guest can fully absorb the site’s quiet grandeur.

These evocative images were captured by former Mathieson team member Young Ah Goh, whose keen eye for composition and light beautifully conveys the observatory’s profound stillness. Reflecting on her visit, she notes:

“There is a quiet reverence to this place—each element, whether stone, timber, or glass, feels intentional and deeply connected to its surroundings. Walking through the observatory, you become acutely aware of the shifting light, the textures underfoot, and the subtle dialogue between past and present.”

At once a sanctuary and a stage for artistic contemplation, the Enoura Observatory stands as a testament to the profound interplay between time, nature, and human intervention—a place where beauty lingers and the spirit of Japan’s artistic heritage endures.
