- Nippon Densetsu Kogyo Co., Ltd. engages primarily in the construction, design, supervision, and maintenance of electrical, information, and communication facilities for infrastructure in Japan. The company operates through key segments including Railways, which encompasses electrified railway equipment such as power generation and substations, transmission lines, electric train lines, electric light power, signals, and communication systems primarily for JR companies, private railways, and public operators; Buildings, covering electrical installations, air conditioning, plumbing, water supply, drainage, and sanitation for facilities like offices, hospitals, hotels, airports, and data centers; Information and Communications Systems, involving mobile base stations, IP networks, optical cables, railway communication, and network infrastructure; Environmental Energy, focused on renewable energy projects including solar and wind power generation, ZEB constructions, and energy efficiency improvements; and Associated Business, which includes real estate leasing and management, electrical equipment maintenance, materials sales, software development, and human resources training at Chuo Gakuen. Founded in 1942 and headquartered in Tokyo, the company conducts nationwide operations with a strong emphasis on railway clients, particularly JR East, and targets growth areas such as data centers and redevelopment projects.
In recent developments, Nippon Densetsu Kogyo established JCroc Co., Ltd. as a wholly-owned subsidiary in October 2025 through an incorporation-type company split to transfer and expand its telecommunications business, enabling more agile strategies in infrastructure sharing and related services; the firm also signed an agreement in October 2025 to designate its new NDK Nagano Building, a ZEB, as a temporary disaster evacuation site for local residents in Nakagosho ward, Nagano City. The company reports robust financial performance with net sales reaching 78.4 billion yen and operating profit of 2.7 billion yen for the six months ended September 30, 2025, driven by high backlog and progress in large-scale projects, while forecasting full-year FY2025 net sales of 230.5 billion yen and profit attributable to owners of 13.4 billion yen, surpassing prior records amid strategic order selection and segment expansions. Additionally, it advances new initiatives like a metal recycling business for construction materials, DX promotion with generative AI pilots, and enhanced partner company support through recruitment and safety training to bolster construction capabilities.
