Business Details
Sells automotive replacement parts and accessories to regional parts wholesalers, car accessory shops, and other outlets, supported by stable demand for replacement parts driven by the maintained number of vehicles owned and the lengthening average vehicle age in Japan. The segment offers core products such as PB products, batteries, suspension products, wipers, and air conditioner filters. Note that from the current consolidated fiscal year, the division overseeing Del Auto Co., Ltd. was transferred to the Industrial Machinery Sales Headquarters, so prior-period comparisons are based on restated figures. Segment profit is calculated on an ordinary income basis.
Recent Overview
Achieved 4.6% year-on-year sales growth driven by steady sales of core products
Full-year net sales for FY2026 (ending March 2026) were ¥32,076 million (up 4.6% year on year), and segment profit was ¥1,520 million (up 2.6% year on year). Core products such as PB products, batteries, suspension products, wipers, and air conditioner filters performed well, with steady sales to major customers. On the other hand, some domestic and overseas customers of domestic consolidated group companies struggled, leading to a decline. SG&A expenses increased 13.5% year on year due to expanded investment in human capital and continued elevated logistics costs. The segment continues to pursue operational efficiency through logistics reform and system upgrades, as well as value chain optimization.
