Business Details

Mainly engaged in the manufacture and sale of Engine Valves, Valve Seat, Cotter, Rotator, Retainer, machinery, and other products, and also conducts logistics and other service activities. In addition to the domestic parent company, the company has built a global production system with overseas subsidiaries in China, Indonesia, and Mexico. Major customers are leading automakers such as Nissan Motor, Toyota Motor North America, and Toyota Motor Corporation. This is the flagship segment, accounting for approximately 96% of consolidated net sales.

Recent Overview

Sales rose 13.1% year on year to ¥27,947 million, but profit fell 9.7% due to higher costs

In FY2026 (ending March 2026), sales achieved a substantial increase to ¥27,947 million, driven by a large increase in sales to North America (up 25.9% year on year) and contributions from new domestic orders. On the other hand, increased costs related to production ramp-up, the impact of U.S. tariffs, rising labor costs, and soaring prices of various materials squeezed profit, with segment profit declining to ¥2,471 million (down 9.7% year on year) and the profit margin falling to 8.8% (from 11.1% in the prior period). Subsidiary Maruyoshi Seisakusho recorded an impairment loss of ¥94 million and is scheduled to be dissolved in September 2026.

Key Products

product
Engine Valve

Intake and exhaust valves for gasoline and diesel engines. The company is pursuing new technology development for carbon-neutral fuel compatibility and higher functionality. Demand has remained solid against the backdrop of decelerating EV adoption and expanding demand for HVs.

product
Valve Seat, Cotter, Rotator, Retainer

Valve seats are press-fit components for cylinder heads, while cotters and retainers are valve fixing components, and rotators are valve rotation mechanism components. These are often ordered together with Engine Valves, supporting long-term trading relationships with customers.

product
Machinery & Tooling

Manufactures and sells dedicated machinery and tooling related to Engine Valve production. Value is created by externally selling the know-how accumulated through in-house production efficiency improvements.

service
Logistics & Packaging Services

Conducts logistics and other service activities related to product manufacturing and sales. Freight and packing expenses accounted for ¥1,070 million of the total SG&A expenses of ¥4,329 million for the current fiscal year, a substantial increase of ¥483 million year on year.

Growth Drivers

  • Continued sales contribution from new order projects that drove a substantial increase in sales to North America (up 25.9% year on year)
  • Solid underlying demand for engine parts against the backdrop of decelerating EV adoption and expanding global demand for HVs (HV/PHEV)
  • Strengthened product competitiveness through the establishment of new technologies for carbon-neutral fuel compatibility and higher-functionality Engine Valves
  • Improved profitability from the establishment of a globally optimized production system (China, Indonesia, Mexico)
  • Expanded opportunities to capture residual market share as competing manufacturers scale down or exit the business
  • Realization of wage increase pass-through to selling prices and continued cost improvement activities

Risks

  • Risk of increased export costs and declining North American demand due to higher U.S. automobile tariffs
  • Risk of further profit margin pressure from increased production ramp-up costs, rising labor costs, and soaring prices of various materials
  • Risk of structural decline in engine parts demand due to the long-term progression of EV adoption
  • Impact of exchange rate fluctuations (particularly the Mexican peso and Chinese yuan) on the performance of overseas subsidiaries
  • Risk of sales concentration in specific customers such as Nissan Motor
  • Risk of continued decline in sales in the Chinese market (sales to China also declined in the current period)
