What IPC does

IPC (株式会社アイピーシー) is a Japanese wood products trading corporation founded in 1961 and headquartered in Fuchu City, Hiroshima Prefecture. The company specializes in the import, export, and domestic distribution of laminated lumber products, with a particular focus on paulownia wood in which it claims to be Japan's leading handler. Its product portfolio covers laminated lumber across multiple species (paulownia, pine, acacia, ash, rubber wood, and baked paulownia), plywood, 2x4 structural materials, and made-to-order private-brand items, with multi-stage quality inspection and F☆☆☆☆ certification under Japan's highest formaldehyde emission standard.

The firm operates a global sourcing network spanning seven countries — China, Canada, Sweden, Latvia, New Zealand, and Indonesia — anchored by a joint venture in China and a Nanjing office opened in 1995. IPC maintains direct factory relationships in each sourcing geography, providing vertical reach into upstream production rather than acting purely as an intermediary. This supply chain structure is the operational backbone that allows the company to serve Japanese customers with both commodity and specialty wood products.

IPC sells through two channels. The B2B segment supplies home centers, building material manufacturers, wooden box makers, and wholesalers. The B2C segment is served through the IPC DIY Lab. e-commerce platform launched in June 2015, with distribution extended across Rakuten, Amazon, and Yahoo! Shopping marketplaces. The company is family-owned (Imai family), with capital stock of JPY 30 million and a workforce of approximately 18-25 employees, making it a small specialist in the Japanese wood trading landscape rather than a generalist shosha.

• Sumitomo Forestry: Major Japanese timber and housing company with vertically integrated operations from forestry to home construction. Comparable to IPC as a Japanese lumber trading/processing player, but vastly larger in scale and scope, with broad incumbent positioning across the entire wood value chain.
