Toami

What Toami does

Toami Corporation is a 135-year-old Japanese manufacturer of welded wire mesh and related reinforcement products, founded in 1890 in Osaka, listed on the Tokyo Stock Exchange (TYO: 5973) since 2019, and the only listed pure-play company in Japan's welded wire mesh industry. The company operates 12 factories nationwide (Kanto, Chubu, Kansai, Chugoku, Kita-Kyushu, Minami-Kyushu) and manufactures welded wire mesh, hooping bars (フープ筋), shear reinforcement rebar, mesh fences, pest intrusion fencing, spacers, and specialty mesh products. Toami's core technology rests on proprietary wire mesh welding machines developed in-house since approximately 1950 — a capability the company has also exported — and on internally developed production management and estimation software used across the group's Vietnam operations.

The group's revenue model is anchored by direct B2B sales of welded wire mesh and reinforcement materials to general contractors (ゼネコン), concrete product manufacturers, and public-sector clients, with pricing negotiated per project (no public pricing). Since 2021, Toami has executed an aggressive vertical integration strategy, acquiring four construction-segment subsidiaries (Watabe Construction, Nakajo Komuten, Erde, and Arakiji Komuten) and consolidating FD Techno (Fabdeck reinforced deck plates), effectively evolving from a standalone materials manufacturer into an integrated materials-plus-construction group that supplies reinforcement materials and provides on-site installation/formwork services. International operations are conducted through a Vietnam joint venture (SMC TOAMI, est. 2015 with SMC Vietnam and Hanwa Co.) and a fully owned Vietnam subsidiary (TOAMI VIETNAM, est. July 2025) performing estimating services and trading intermediary functions. Marketing and distribution are conducted through direct factory-attached sales offices, a corporate website, and a corporate blog — no e-commerce, self-serve, or marketplace channels are used.

Revenue model

1. Welded wire mesh and construction material product sales: Core revenue driver: manufacturing and selling welded wire mesh ( wire mesh), rebar加工品 (shear reinforcement bars / hooping bars), mesh fences, and other civil engineering/construction materials. Products are sold directly to construction sites, general contractors (ゼネコン), and public sector clients across Japan through regional sales offices.
2. Construction/engineering services (through group companies): Through subsidiaries (渡部建設, 中條工委店, エアード, アラキヂ工委店), the group provides construction and engineering services including formwork construction (型枠工事), civil engineering施工管理, road paving, and wire mesh installation at construction sites. Revenue is generated from project-based construction contracts.
3. Fabdeck floor slab sales (via FD Techno JV): FD Techno (joint venture with Itochu Marubeni Sumitomo Technosteel) manufactures and sells Fabdeck floor slabs (reinforced deck plates) used in building construction. This extends Toami Group's reach to construction projects that do not primarily use welded wire mesh.
4. Estimation (積算) services (via TOAMI VIETNAM): TOAMI VIETNAM performs estimation work — analyzing structural drawings and inputting data into estimation software — for the group's domestic factories and external clients, including residential foundation rebar estimation. Revenue from third-party estimation contracts.
5. Trading/sourcing intermediary (商社員): TOAMI VIETNAM also functions as a trading business, exporting products from Vietnam to Japan and introducing local companies to Japanese clients. Revenue from intermediary margins and trading activities.
