Publication of Independent Research Report: "System Building Market 2026" on Japan's System Building Market

Marketing and Associates Co., Ltd. (Chiyoda-ku, Tokyo) will publish the independent research report "System Building Market 2026: Analysis and Outlook of the Japanese System Building Market (FY2021-FY2026)" on April 13, 2026, based on interviews with relevant parties and public information. At the same time, we have released a media summary outlining the key points for the press. The summary can be viewed on this release page and downloaded as a PDF document.

*In this survey, "system building" refers to a construction method for non-residential buildings, mainly steel structures, that realizes shorter construction periods, cost reductions, and quality standardization through the standardization of components (steel frames, roofs, outer walls, fittings, etc.) and the systematization of the design, manufacturing, and construction processes.

As the investment environment surrounding construction, logistics, and manufacturing changes, building plans for factories, logistics facilities, hazardous materials warehouses, and cold storage warehouses are required to simultaneously meet multiple requirements such as time to operation, legal compliance, temperature management, BCP, and decarbonization, in addition to mere construction costs. Against this background, system building has gone beyond the framework of a "construction method" and is attracting increasing attention as an option that supports the speed of business launch and stable operation. In order to grasp this change quantitatively and qualitatively, our company has organized the market through interviews with major companies and matching public information.

In this survey, the Japanese system building market is organized on a manufacturer function basis (building costs/material costs + construction costs; foundations, exterior structures, facilities, etc. are generally excluded). Based on the total of the seven major companies, the market size is expected to expand from 138.45 billion yen in FY2021 to 198.16 billion yen in FY2026, with a compound annual growth rate (CAGR) of 7.4% for FY2021-2026. What supports market expansion is not so much the rapid expansion in the number of projects itself, but rather the increase in high-specification projects such as logistics reorganization, manufacturing investment, hazardous materials warehouses, and cold storage warehouses, as well as an increase in unit prices backed by rising material and labor costs and advanced specifications.

Looking at the market structure in FY2025, Yokogawa Bridge System Building leads with 24.3%, followed by Nippon Steel Engineering with 21.5%, Nippon Steel Trading System Building with 15.7%, and JFE Civil with 15.1%, with the top four companies accounting for 76.6%. The market remains highly concentrated at the top, but the survey also revealed that in application-specific areas such as hazardous materials, cold storage, and multi-story logistics, differences in proposal capabilities, supply systems, and legal compliance capabilities leave room for a direct impact on competitiveness. The fact that the market size is being driven up not only by accumulated volume but also by an increase in project unit prices and specification levels is an important point to understand the current market.
