Business Details

The core business of the Seiren Group, manufacturing and selling interior materials for automobiles and railway vehicles (car seat surface materials, airbags, decorative components). Domestically handled by the Company on a standalone basis and by KB Seiren Co., Ltd., with overseas operations conducted globally through local subsidiaries in the United States, Mexico, Thailand, China, Brazil, India, Indonesia, and Hungary. NB Seiren Co., Ltd. Automotive Materials, which became a consolidated subsidiary in January 2026, was added to this segment, and the segment achieved overall increases in both revenue and profit driven by a recovery in domestic orders and higher overseas revenue and profit.

Recent Overview

Net sales up 5.0% and operating income up 16.1%, reaching a record high, driven by domestic order recovery, overseas revenue and profit growth, and the integration of NB Seiren.

In the Vehicle Materials business for FY2026 (ending March 2026), net sales reached ¥115,258 million (up 5.0% year on year) and operating income reached ¥16,199 million (up 16.1% year on year). Domestically, car seat material orders recovered from the previous year's decline caused by automaker production stoppages, resulting in higher revenue and profit. Overseas (January to December 2025), although sales in the United States declined due to a pullback from the prior year's strong performance, expanded orders from new model launches at the Mexico plant, increased car seat material sales in the Asia region, and quality improvement and cost reduction activities at each site contributed to higher revenue and profit. In addition, NB Seiren Co., Ltd. Automotive Materials, consolidated in January 2026, was added, contributing to the segment's overall increase in revenue and profit.

Growth Drivers

  • Recovery in orders driven by normalization of production at domestic automakers (rebound from the previous year's production stoppages)
  • Expanded orders accompanying the launch of new models at the Mexico plant
  • Increased sales of car seat surface materials and airbags in North America and Southeast Asia
  • Improved profitability through quality improvement and cost reduction activities at overseas sites
  • Revenue and profit contribution from the business integration of NB Seiren Co., Ltd. (from January 2026)
  • Improved profit margin through changes in product mix toward high-value-added products (Cuore®, etc.)

Risks

  • Impact on automobile production and demand from US trade policy (tariffs) and geopolitical risks
  • Risk of overseas business profits being reduced by exchange rate fluctuations (particularly yen depreciation or appreciation)
  • Risk of production stoppages or cutbacks by domestic automakers (due to quality issues, certification fraud, etc.)
  • Risk of rising costs for raw materials and transportation, etc.
  • Profit pressure from increased depreciation expense related to carbon-neutral equipment
  • Risk of changes in the demand structure for automotive interior materials due to progress in EV adoption
