MOKUZAI LTD

What MOKUZAI LTD does

MOKUZAI LTD (trading as North21 Limited) is a family-owned direct supplier of authentic Japanese timber headquartered in St Heliers, Auckland, New Zealand, with a Japan office in Shimada City, Shizuoka. The company is operated by Graham and Ren Sayer, a father-and-son team leveraging Graham's 45+ years of Japanese business experience. Mokuzai sources Sugi (Japanese Cedar), Hinoki (Japanese Cypress), Karamatsu (Japanese Larch), Todomatsu (Japanese White Fir) and other native species directly from certified family-owned Japanese mills, bypassing intermediaries and trading houses, with all mill communication conducted in Japanese.

The product portfolio is organized across three processing stages. Unfinished products comprise rough-sawn kiln-dried or green lumber in four primary species. Semi-finished offerings include JAS-engineered Sugi beams, live-edge Sugi boards, collector-grade Yoshino slabs from Nara Prefecture, Hinoki turning blanks, and architectural veneer. Finished products include boxed yakisugi cladding in four finishes, solid Hinoki underfloor heating flooring validated through 1,100 hours of continuous heat testing, Sugi mirror-pattern interior panels, and hand-polished Yoshino logs produced using a 600-year-old traditional craft. A Japanese Design & Materials Sourcing service connects international clients with vetted Japanese architects and craftsmen. The entire supply chain carries GOHO certification, Japan's government-administered verification of sustainable and legal timber that satisfies FSC and PEFC due diligence requirements.

Mokuzai operates a direct sales model with quote-based pricing across most products, responding to inbound enquiries within two business days. Customers are international architects and designers specifying Japanese-inspired projects, high-net-worth residential clients, wellness and hospitality developers, distributors and agents purchasing brandable boxed yakisugi, and individual woodworkers ordering Hinoki turning blanks via EMS courier. Distribution combines direct project sales, a distributor/reseller channel for packaged yakisugi, and a single-box EMS courier channel for turning blanks shipped door-to-door worldwide. Revenue is generated through hardware sales of timber products plus professional services from the design-coordination offering.
