Japan Transportation Consultants

What Japan Transportation Consultants does

Japan Transportation Consultants (日本交通技術株式会社, "JTC") is a privately held Japanese railway civil engineering consulting firm founded in August 1958 by Fujii Matsutaro, a former Japanese National Railways (JNR) Chief Engineer who later became JNR's seventh president. The company delivers four integrated service lines — Survey (調査), Planning (計画), Design (設計), and Maintenance/Renovation (維持管理・リニューアル) — covering the full lifecycle of railway infrastructure including bridges, elevated viaducts, tunnels, underground stations, track, and turnouts, with particular depth in seismic and seismic-isolation design. Since its founding participation in the Tokaido Shinkansen, JTC has worked on every subsequent Shinkansen line and on a broad base of urban rail, subway, and private-railway projects, accumulating approximately 17,450 projects over 65 years at a current run-rate of ~160 projects per year.

JTC earns revenue on a project-completion basis (完成高/完成基準) through professional-services consulting contracts, with pricing set per project and not publicly disclosed. Go-to-market is sales-led and direct: the firm engages JR companies, major private railways (Tokyu, Keikyu, Seibu, Kintetsu, Hanshin, Sagami, Keisei, etc.), municipal subway operators (Tokyo Metro, Toei, Yokohama, Sendai, Sapporo), and government clients (MLIT, prefectural and municipal authorities). Customer segments are split primarily across JR Group Railway Operators and Private Railway Companies, with secondary exposure to Municipal/Urban Subway Operators and National/Local Government Agencies.

Operations are anchored at the Tokyo headquarters in Taito-ku and supported by four regional branches (Sapporo, Nagoya, Osaka, Fukuoka) and sales offices in Sendai, Saitama, Chiba, and Yokohama, covering Hokkaido through Kyushu. As of April 2026, JTC had 159 employees including 49 Professional Engineers (技術士) and 129 technical staff (104 male, 25 female), and generated ¥2.56 billion of FY2025 completed project value. The company is led by President and Representative Director Tachiyama Masaru (since 2021) and was reorganized in 2023 into three headquarters (Management, Business Management, Business Promotion). In December 2025, JTC received a cease-and-desist order and surcharge payment order from the Japan Fair Trade Commission in connection with antitrust violations — a material legal/operational event against an otherwise stable 65-year operating record.
