Business Details

This segment centers on the manufacture, sale, and repair of marine and port equipment, with Tokyo Keiki's core operations handling the manufacture and sale of marine equipment. Its revenue base rests on equipment sales to the domestic and overseas newbuilding vessel market and high-level demand for maintenance services. In FY2026 (ending March 2026), revenue increased, but operating profit declined due to higher R&D expenses and other costs. The overseas sales ratio was high at 62.5% (¥8,545 million) of total revenue, giving the segment a structure in which performance is influenced by trends in the global shipbuilding market.

Recent Overview

Revenue increased, but operating profit fell 15.1% due to higher R&D expenses; order backlog rose 28.1%, indicating solid future demand

In FY2026 (ending March 2026), steady progress in demand for equipment for newbuilding vessels and continued high-level maintenance service demand drove revenue to ¥13,675 million (+9.1% year on year). On the other hand, operating profit declined to ¥1,317 million (-15.1% year on year) due to increased R&D expenses and other costs, with operating margin falling from 12.4% to 9.6%. Orders received rose to ¥15,280 million (+10.6% year on year), and the order backlog expanded to ¥7,309 million (+28.1% year on year), broadening the future revenue base. For FY2027 (ending March 2027), revenue of ¥14,800 million (+8.2%) and operating profit of ¥1,370 million (+4.0%) are forecast.

Recent Overview

Revenue was flat year on year, but operating profit fell 9.4% due to a decline in the railway equipment business

Full-year revenue for FY2026 (ending March 2026) was ¥4,249 million (+¥2 million, +0.0% year on year), essentially unchanged from the prior period. The railway equipment business saw a revenue decline due to a decrease in the number of units sold of the mainstay Ultrasonic Rail Flaw Detection Car, but the inspection equipment business trended solidly, supporting overall results. Operating profit declined to ¥684 million (-¥71 million, -9.4% year on year). Orders received increased significantly to ¥5,572 million (+¥906 million, +19.4% year on year), and the order backlog also surged to ¥3,472 million (+¥1,322 million, +61.5% from the prior period-end), advancing the accumulation of future revenue. For the next fiscal period (FY2027, ending March 2027), revenue of ¥4,700 million (+10.6%) is expected, while operating profit is forecast to decline to ¥510 million (-25.5%) due to an increased depreciation burden associated with the head office relocation and other factors.
