Business Details
Consists primarily of Aisan Industry Co., Ltd. itself and its domestic consolidated subsidiaries (Teikei Carburetor, Nichi-Alloy, Aisan Kumamoto, etc.). Centered on the manufacture and sale of automotive parts such as Fuel Pump Modules, Throttle Bodies, and Canisters, the segment also operates diversified businesses including the Motor Vehicle Transportation Handling Business, Civil Engineering & Construction, and Computer System & Program Development and Sales. The main customer is the Toyota Motor Group, which accounts for approximately 49% of total group sales. Also includes inter-segment internal sales (parts supply to other regions).
Recent Overview
Both sales and operating income increased significantly year on year, driven by higher sales volume and improved profitability
In the Japan segment for FY2026 (ending March 2026), sales increased to ¥139,595 million (up 4.5% year on year) due to higher sales volume. Operating income rose sharply to ¥3,160 million (up 36.3% year on year), reflecting the effects of profitability improvement initiatives. Capital expenditures surged to ¥17,511 million from ¥7,292 million in the prior period, with active investment in domestic production infrastructure centered on increases in buildings and structures. Separately, effective April 1, 2026, the company made Trice Corporation, the world's No.1 manufacturer of carbon parts (acquisition cost ¥7,500 million), a subsidiary, and its contribution to the Japan segment is expected from the following period onward.
Key Products
Growth Drivers
- Increase in sales volume (recovery in domestic automobile production and expanding demand for hybrid vehicles in North America)
- Strengthened cost competitiveness through continued penetration of profitability improvement activities (MMK activities, etc.)
- Improved profitability in the Fuel Pump Module business through in-house production and type consolidation
- Expanded orders for electrification products (busbar ends for HVs, high-voltage junction boxes for FCVs, etc.)
- Incorporation of carbon parts technology and strengthened product competitiveness in the powertrain business through the acquisition of Trice Corporation as a subsidiary
- Improved production capacity and competitiveness through active investment in domestic production facilities (capital expenditures of ¥17,511 million for FY2026, ending March 2026)
Risks
- Spillover effects on domestic production and exports from weak sales by Japanese automakers in the Chinese market
- Cost increases due to U.S. tariff policy (affecting the group overall, with the Americas segment operating income already showing a 38.5% year-on-year decline)
- Medium- to long-term risk of declining demand for internal combustion engine-related parts (Fuel Pump Modules, etc.) due to accelerating EV adoption
- Impact of exchange rate fluctuations (yen appreciation) on export profitability and inter-segment internal sales
- Customer concentration risk due to sales concentration in the Toyota Motor Group (approximately 49% of total group sales)
- Risk of future profit pressure from increased depreciation expenses accompanying the sharp rise in capital expenditures (approximately 2.4x year on year)
- Risk of goodwill recognition and integration costs arising from the acquisition of Trice Corporation
