About Shirokane-Takanawa

Set in Shirokane-Takanawa, Minato City, Tokyo, OK PRIME pursues not just architectural beauty but value that stands the test of time.
The building draws on the cultural richness of classic European streetscapes, with a finely detailed facade, layered material textures, refined metalwork and the interplay of light and shadow coming together to create a calm, elegant city landscape.
Just as a lighthouse guides those at sea, OK PRIME aims to protect the quality of life of every resident and the asset value of every investor — shining with a steady, warm light through the bustle of the city and the passing of the years.
The entrance gate, welcome corridor, lobby and every last detail reflect our dedication to quality and our commitment to the future. Through a constant pursuit of design, craftsmanship and living aesthetics, we create core assets worth holding for the long term and passing down for generations.
OK PRIME believes true value lies not only in today, but in the future.
