Business Details
Comprising Okuma Corporation itself and its consolidated subsidiaries, this segment manufactures and sells machine tools such as NC lathes, machining centers, multitasking machines and NC grinding machines, and also provides after-sales service. It serves as the core of the Group's overall production and also handles internal transfers to overseas segments. It rolls out automation and labor-saving solutions globally for growth industries such as aerospace, defense, medical equipment, and semiconductor-related fields.
Recent Overview
External sales increased significantly, but segment income declined slightly due to lower internal transfers and higher costs
In the Japan segment for FY2026 (ending March 2026), sales to external customers rose significantly to ¥117,355 million (up 22.2% year on year), while inter-segment internal sales decreased to ¥63,765 million (down 10.9% year on year). Segment income declined to ¥8,830 million (from ¥9,241 million in the prior period). Persistently high material and transportation costs, increased investment in human capital, and low capacity utilization in the first half weighed on profit. On the capital expenditure front, the Okuma PDC was completed in September 2025 and began operating in January 2026, and Dream Site Engineered Solutions was completed and began operating in January 2026; the increase in property, plant and equipment and intangible assets expanded to ¥25,700 million, 2.2 times the prior period level.
Key Products
Growth Drivers
- Expanding capital expenditure demand from growth industries such as aerospace, defense, medical equipment, data centers, and energy (which also became more active domestically in the second half)
- Sustained mid- to long-term underlying demand for labor-saving and automation solutions amid a declining working population in Japan and overseas
- Strengthened automation solution proposal capability and production capacity following the launch of Dream Site Engineered Solutions and the Global Innovation Center
- Logistics efficiency improvements, cost reductions, and Scope 3 greenhouse gas emission reductions from the operation of the Okuma PDC
- Securing sales and profit going forward on the back of a substantial order backlog (Group total of ¥101,407 million)
- Increased production capacity from the expansion of assembly space at the Head Office Plant and Kani Plant, centered on 5-Axis Control Machining Centers and Multitasking Machines
Risks
- Continued cautious capital expenditure stance among mid-tier and small businesses (including the impact of US tariff measures on automobiles), leading to sluggish plant utilization rates
- Profit pressure from persistently high material and transportation costs and increased investment in human capital
- Negative impact of uncertainty over US tariff policy on capital expenditure by Japan's export industries
- Difficulty in leveling out sales and profit due to the concentration of contracted delivery dates for order-based machines in the second half of the fiscal year
- Risk of fluctuation in inter-segment internal transfer sales linked to demand trends in overseas segments (down 10.9% year on year in the current period)
- Risk of margin decline due to increased depreciation expenses associated with large-scale capital investments (PDC, Dream Site, etc.)
