Nippon Hume

What Nippon Hume does

Nippon Hume Corporation (日本ヒューム株式会社, ticker 5262.T on the Tokyo Stock Exchange Prime Market) is a 100-year-old Japanese manufacturer of precast concrete products for civil engineering and infrastructure applications. Founded in 1925 as Japan's pioneer Hume pipe producer and headquartered at 5-33-11 Shimbashi, Minato-ku, Tokyo, the company operates six ISO9001-certified manufacturing factories (HQ, Kumagaya, Tomakomai, Mie, Amagasaki, Kitakyushu) and four regional sales branches (Sapporo, Nagoya, Osaka, Fukuoka). Its product portfolio spans Hume pipes, concrete piles, RC segments, composite steel pipes, PC wells, box culverts, arch culverts, modular culverts, guard fences, parapets, antibacterial concrete (Bikkuriito), optical-fiber-compatible products, and the e-CON® low-carbon concrete platform.

The business operates a vertically integrated one-stop model covering design, manufacturing, and construction of precast concrete products for sewerage, water supply, drainage, stormwater management, expressway, railway, and tunnel applications. Customers are primarily national and local government agencies (MLIT, prefectural and municipal authorities) and expressway operators (NEXCO East/West/Central, Hanshin Expressway), with private construction companies serving as project-based intermediaries. Revenue streams include hardware sales of precast products, construction and installation services, optical fiber cable installation, sewer pipe line rehabilitation and AI/drone-based diagnosis, real estate and environmental operations, and an overseas licensing/international business. Pricing is quote-based for most B2B infrastructure contracts, with an online quotation simulation tool for optical fiber installation work.

Recent strategic activity centers on inorganic expansion and digital innovation: the company completed the acquisition of Manac Co., Ltd. (February 2026) and announced the acquisition of Chubu Kiso Co., Ltd. (June 2026) as a wholly-owned subsidiary, entered a capital and business partnership with Liberaware for drone-based AI sewer inspection (March 2026), and announced the Medium-Term Management Plan '26-30 Plan NEXT 100' coinciding with its 100th anniversary in October 2025. The company also launched digital products NH-ROBOCON (robotic concrete pouring), NH-GFAS® (design automation), and the Pile-ViMSys® DX construction management system, alongside proprietary low-carbon concrete e-CON®, which became the first domestic product registered as 'Eco Materials for Sewerage' and won the 34th Earth Environment Award (Minister of the Environment Award).
