Artisan craftsmanship meets modern building technology

OK PRIME Advisor
Our tiles are Mino-yaki, a traditional Japanese craft with 1,300 years of kiln-firing heritage.
The exterior tiles are top-grade Class BI porcelain — under 1% water absorption and extremely durable.
A 5:9:4 golden blend gives the walls subtle depth in every kind of light.

At OK PRIME Shirokane-Takanawa, every material — from the exterior tiles to the coating system — reflects an uncompromising commitment to quality. We've chosen Japan's highest-grade building materials and centuries-old craftsmanship to create a central Tokyo asset that only gets better with time.

01 — Mino-yaki · Traditional Craft

Authentic Mino-yaki heritage — a treasured Japanese craft over 1,000 years in the making

Mino-yaki · Traditional Craft© SK KAKEN

Mino-yaki ceramics have a history of more than 1,300 years and are officially designated a Traditional Craft by the Japanese government. Chōkō Tōgyō has taken this kiln-firing technique, once reserved for fine tea ware and tableware, and adapted it perfectly for modern exterior tiles. By bringing the wabi-sabi aesthetic of the Japanese tea ceremony to the facade, your home gains more character the longer you live in it.

02 — Golden Blend · Artisan Mixed

An exclusive 5:9:4 golden blend — depth and dimension, precisely mixed by artisans

Artisans precisely mix three shades of deep gray — dark, medium and light — in a perfect 5:9:4 ratio and lay them in a random mesh-backed pattern. In natural light at different times of day, or after a rain shower, the wall reveals remarkably subtle depth and texture. It's a quiet kind of luxury that instantly elevates the entire building.

03 — Class BI Porcelain · Top Grade

Top-grade Class BI porcelain — durability built for extreme climates

These tiles are classified as Class BI (porcelain), the top grade with the lowest water absorption (typically under 1%) and the highest firing temperature (over 1,200°C). The catalog specifically rates them "Frost Resistance ◎" — proven even in Japan's coldest regions — so in milder climates they keep the facade looking new for 30 years, saving significantly on exterior cleaning and maintenance.

04 — 45 Nichokake · Flanca

45 Nichokake Flanca (mesh-backed) — handcrafted texture with efficient installation

The 45 Nichokake Flanca series uses the classic nichokake proportions of Japanese architecture to create refined lines. Supplied on mesh backing, it keeps the fine detail of small tiles while making on-site installation much faster and more even.

Product Advantages
  • Exceptional Durability

    A cross-linked coating with siloxane bonds effectively resists UV rays, moisture and other causes of polymer aging, protecting the building's exterior for the long term.

  • Superior Stain Resistance

    The dense cross-linked coating keeps airborne dust and exhaust fumes from sticking, delivering outstanding resistance to dirt.

  • Mold & Algae Resistant

    A special formulation prevents mold, algae and other microbial growth over the long term, keeping the building's surfaces clean and hygienic.

  • Eco-Friendly & Safe

    A water-based paint (thinned with water) with no risk of solvent poisoning or fire, making the job site safer for workers.

  • Boosts Asset Value

    More durable than conventional acrylic or polyurethane paints, with a lower overall life-cycle cost that helps raise the building's asset value.

  • Distinctive Look & Feel

    A richly textured, dimensional surface paired with a pearlescent glaze with its own unique sheen creates visual depth and material beauty that's hard to replicate.
