Taisei Corporation

Company Overview

Taisei Corporation is one of Japan's leading general contractors, incorporated in December 1917 and headquartered at 1-25-1 Nishi-Shinjuku in Tokyo. The company employs approximately 9,500 people and operates through a national network of branches covering Sapporo, Sendai, Saitama, Chiba, Tokyo, Yokohama, Niigata, Nagoya, Osaka, Kobe, Kyoto, Hiroshima, Takamatsu and Fukuoka, alongside a dedicated International Operations Headquarters.

Core Business Areas

Building Construction

Taisei designs and builds offices, hotels, hospitals, cultural facilities, industrial plants and residential developments. Projects such as The Okura Tokyo illustrate the standard of work at the top of the Japanese market, where craftsmanship expectations and seismic requirements are both exceptionally demanding.

Civil Engineering

A separate Tokyo Civil Engineering Branch reflects how substantial this side of the business is. Work covers tunnels, bridges, dams, ports, railways and urban infrastructure - including projects such as the Tokyo Umi no Mori Tunnel.

Real Estate Development

The company develops and invests in property in its own right, giving it exposure to asset performance rather than construction margin alone.

Engineering and Group Services

Taisei Group companies extend the business into specialist engineering, facility management and related services across the asset lifecycle.

Technology and Research

The Taisei Advanced Center of Technology gives the company a substantial in-house research capability - a defining feature of the major Japanese contractors, which invest in R&D at a level uncommon among Western builders. Its best-known output is T-eConcrete with Carbon-Recycling, a carbon-recycled concrete developed to cut the embodied emissions of one of the most carbon-intensive materials in construction. Related initiatives include the CDE3 Company concept and its New Normal Architecture programme.

Overseas Operations

Taisei has a long record of international work delivered through its International Operations Headquarters and overseas network, spanning infrastructure and building projects across Asia and beyond. That history gives the firm experience of financing structures, joint ventures and local partnerships well outside the Japanese domestic model.

Strategy: TAISEI VISION 2030

The company's direction is set by TAISEI VISION 2030 and its associated Medium-Term Business Plan for 2024 to 2026, which frame targets around business performance, sustainability and technology adoption. Its stated theme - comfortable connections creating new lifestyles - reflects a shift from delivering buildings toward shaping how places are used.

Sustainability and Governance

Sustainability is organised around environmental, social and governance pillars, with decarbonisation of materials and construction processes as a central technical challenge. Corporate governance, disclosure and integrated reporting are handled to the standard expected of a listed Japanese company.

Market Position

Taisei sits among the largest general contractors in Japan, competing directly with the other major national builders. Its combination of building construction, civil engineering, development and deep in-house research is a structural advantage that few contractors anywhere can match.

Why AEC Teams Should Know Taisei

For anyone tracking low-carbon concrete, seismic design or contractor-led research and development, Taisei is one of the most important companies to follow in the global built environment.
