Business Details

An automotive parts segment that manufactures and sells Coil Springs / Leaf Springs, Stabilizers, Accumulators, Torsion Bars, Stabilizer Links, and Stabilinkers. Manufacturing and sales are conducted at sites in Japan, Thailand, North America, Europe, China, India, Mexico, and elsewhere. The segment supplies key parts essential to automotive suspension systems, and is required to respond to demands for weight reduction, higher durability, and space savings.

Recent Overview

Despite lower domestic demand, price pass-through progress in Thailand and increased volume for some vehicle models drove a 56.6% year-on-year increase in operating profit

In the Suspension Springs Business for FY2026 (ending March 2026), net sales were ¥167,417 million (down 1.0% year on year) due to a decline in domestic demand. On the other hand, operating profit improved significantly to ¥727 million (up 56.6% year on year), supported by progress in passing on higher raw material and other input costs to product prices in Thailand and increased unit volume for some vehicle models. For the next fiscal year (FY2027 (ending March 2027)), further profit improvement is expected, with net sales forecast at ¥164,000 million and operating profit forecast at ¥4,000 million.

Risks

  • Risk of decreased sales volume due to sluggish automobile demand in Thailand, Japan, and elsewhere
  • Risk of increased fixed costs, including one-time expenses associated with the launch of new products in Mexico
  • Risk of rising costs for raw materials, logistics, energy and utilities, etc.
  • Difficulty in securing a stable workforce at North American sites
  • Risk of global production site reorganization associated with progress in vehicle electrification (BEV adoption)
  • Risk of deteriorating business environment due to trade policy reviews (tariffs, etc.) in various countries
  • Risk of profit pressure from intensifying price competition
