Tokyo Board Industries

What Tokyo Board Industries does

Tokyo Board Industries Co., Ltd. (東京ボード工業株式会社) is a Japan-based, publicly listed manufacturer of particleboard and structural wood panels, trading on the Tokyo Stock Exchange under ticker 7815. Founded approximately 90 years ago, the company operates three production facilities across the Kanto region — in Tokyo, Chiba, and Saitama — supported by three group companies. Its two flagship product lines are E.V.A Board (particleboard) and Wall Warrior (structural panel), sold primarily into the Japanese construction industry.

The company's core manufacturing platform uses wood waste as effectively 100% of raw material input, operating a material recycling model that has been in continuous operation since 1991. It holds multiple industry certifications, including JIS standards, ISO 14001 environmental management, EPD (Environmental Product Declaration), and PEFC-COC chain-of-custody certification, which qualify its output for green-construction procurement frameworks. Recent operational history is non-linear: a 2020 fire, a November 2024 fatal accident at a subsidiary, and a late-2024 smoldering incident at the Sakura factory that suspended production until June 2026 — alongside a December 2025 capital reduction and 2026 divestiture of the Shimbashi headquarters and legacy particleboard factory.

Tokyo Board Industries generates revenue through B2B sales of particleboard and structural panels to Japanese construction customers, including general contractors, on-site construction operations, and local builders. The firm employs a horizontal segmentation approach across customer types and relies on Kanto-region logistics density, with no publicly disclosed pricing model, contract structures, or named anchor customers in the available input.

Core offering

Tokyo Board Industries manufactures and sells JIS-standard particleboard (E.V.A Board) made from approximately 100% wood waste as raw material, along with Wall Warrior long-length structural panels for seismic reinforcement. The company also operates a wood waste material recycling and acceptance service for construction sites under a 'minus cost' model, accepting wood waste in exchange for payment that offsets raw material costs. The product line targets construction companies, general contractors, builders, and furniture/interior manufacturers.

Product overview

Tokyo Board Industries operates as a particle board manufacturer with two core products: the EVA Board (E・V・A ボード), a JIS-standard particle board made from approximately 100% wood waste that serves as the company's main product since its establishment, and the Wall Warrior (壁武者), a long structural panel designed for seismic reinforcement. Both products are manufactured through a material recycling process that avoids incineration, enabling carbon fixation by storing CO2 within the boards rather than releasing it into the atmosphere.
