What Sanritsu does

Sanritsu Corporation (三立建材株式会社) is a privately held Japanese export trading company founded in 1999 that specializes in sourcing and exporting Japanese construction materials to international markets. The company purchases second-grade products, test items, excess inventory, discontinued items, and damaged goods from major Japanese manufacturers, trading companies, house builders, waste management firms, and closing businesses, then resells these materials directly to construction companies and distributors overseas — without using brokers or intermediaries. Its product portfolio spans metal siding (the core product, available in GL galvanium steel, aluminum, and stainless variants), roofing, fibre cement siding, ceramic tiles and natural stone, calcium silicate boards, insulation, hot-rolled and cold-rolled steel coils and sheets, wood and resin flooring, resin siding, windows and sashes, decorative panels, doors and frames, decorative sheets, custom millwork, and housing equipment.

The business operates through three integrated functions: (1) direct export trading of Japanese construction materials to 24+ countries across East Asia, Southeast Asia, South Asia, Oceania, Africa, the Middle East, Russia, Nordic countries, and South America; (2) full-service import/export agency handling documentation, logistics, cargo handling, and customs clearance; and (3) warehouse operations at the 10,000 sqm Ichihara Yard in Chiba Prefecture, equipped with 24-hour surveillance, forklifts, excavators, a certified 60-ton truck scale, radiation sensors, and hydraulic press machinery. The company maintains two wholly-owned subsidiaries — Recycle Corporation in Japan (recycling operations) and SANRITSU LANKA PVT LTD in Sri Lanka (regional market entity for South Asia) — both established in 1999.

The company is led by Representative Director Kenji Inagaki (稲垣建史), headquartered in Katsushika-ku, Tokyo, with no public listing, no outside funding, no certifications, and no proprietary technology disclosed. Pricing is quote-based for B2B transactions and not publicly disclosed.
