Key Products
Growth Drivers
- Revenue diversification through expanded domestic sales of mass-production parts for automobiles

- A stable domestic revenue base driven by increased domestic sales of mass-production parts for motorcycles and automobiles
- Policy of using the Vietnamese subsidiary as a strategic base in Southeast Asia to expand into industries beyond the transportation equipment sector and expand ASEAN business
Risks
- Risk of declining sales at the Vietnamese subsidiary (YAMAZAKI TECHNICAL VIETNAM CO.,LTD.), which materialized in FY2026 (ending March 2026)
- Risk of sales concentration on the main customer, Yamaha Motor Co., Ltd. (accounting for approximately 67.2% of segment net sales in the current period)
- Risk of responding to structural changes in the automotive industry driven by EV adoption and progress in CASE technologies
- Impact of foreign exchange fluctuations (yen appreciation) on the earnings of the Vietnamese subsidiary
- Risk of rising manufacturing costs due to soaring raw material and energy prices
- Impact on automobile demand from geopolitical risks such as U.S. trade policy and the situation in the Middle East
