More About Us
SETOUCHI RETREAT by Onko Chishin embodies the philosophy of Minimal Luxury—shedding superfluity to rediscover your authentic self through tranquil retreat experiences. Our seven distinctive all-suite accommodations include rooms with sweeping views of Setouchi’s azure waters, garden suites with private greenery, and suites featuring semi-open-air onsen sleeping baths. Each space offers its own unique character, where time flows in gentle detachment from daily life.
Within this architectural masterpiece, contemporary art seamlessly converges with Tadao Ando’s concrete poetry—from minimal installations by international artists to works by emerging Japanese creators exploring nature’s ephemeral beauty. Our dining presents exquisite Japanese cuisine celebrating Setouchi’s oceanic treasures and mountain bounty, while our spa provides all-hand treatments featuring yuzu and mikan citrus oils (day visitor access available). Complete with infinity pool and private sauna, guests can immerse themselves in the luxurious serenity of a retreat where art, architecture, and nature embrace in perfect harmony.




Environment
Located approximately 50 minutes from Matsuyama Airport and 35 minutes from JR Matsuyama Station, we rest atop a scenic hillside overlooking the Seto Inland Sea in Matsuyama, Ehime Prefecture. Designed and architected by Tadao Ando, this former museum has been reborn as a seven-suite retreat. Our elevated position offers sweeping views of the Setouchi waters, with spaces including an infinity pool, private pools, onsen jacuzzi, and art lounge—creating a retreat where tranquility and refinement resonate in perfect harmony.
Reviews
Extraordinary architecture, excellent service and good food. The in-room onsen has flat bed which is very relaxing I could stay there for a whole day. The hotel only has 7 rooms, very quiet and peaceful.

Here, we once again experience the “art of hospitality”! Master Ando’s design brings the beauty of nature…the full moon outside the floor-to-ceiling windows at dinner, the rainbow that appears when the morning mist meets the sunlight outside the floor-to-ceiling windows at breakfast…right before the guests’ eyes! Such delicate and heartfelt attention to detail—we have witnessed it! The quality of the meals is excellent!
