Business Details

The Asia Pacific Business operates manufacturing facilities in Vietnam, Thailand, Japan, North America, and elsewhere, with China serving as its main production base, conducting research, development, design, manufacturing, and sales of coil-related components and module products for automotive, industrial, and home appliance applications. In the first quarter of FY2026 (ending March 2026), revenue from external customers was ¥22,589 million, accounting for approximately 59% of the consolidated total. In China, the optimization of manufacturing overhead costs (the final year of a three-year plan) is progressing as planned, and efforts to improve profitability are being advanced while maintaining a local-for-local production system.

Recent Overview

Revenue increased 2.8% year on year, but segment profit decreased 21.4%, resulting in lower profitability.

In the first quarter of FY2026 (ending March 2026), automotive-related sales in China and other parts of Asia grew, resulting in revenue of ¥24,545 million (¥22,589 million from external customers), up 2.8% year on year. On the other hand, North America experienced a decline due to the reversal of the prior year's front-loaded demand caused by tariff risk. Segment profit was ¥645 million, down 21.4% year on year, and the profit margin declined to 2.6%. The optimization of manufacturing overhead costs in China has entered the final year of the three-year plan and is progressing as planned.

Key Products

product
Power Inductors & RF Inductors

A broad lineup including high-voltage, high-efficiency products for xEVs. Demand is also expanding for server power supply applications in AI data centers.

product
Power Transformers

Automotive and industrial transformers addressing needs for higher voltage and higher efficiency. Also being expanded into energy storage and robotics applications.

product
Automotive Modules

Addresses the electrification and high-voltage needs of xEVs as a whole, including HVs and PHEVs. Supplied to China, other parts of Asia, and Europe, and performed well again this quarter.

product
Sensors & Actuators

Demand is expanding along with the progress of vehicle electrification. Demand for robotics and medical-related applications is also performing well in other Asian markets.

product
EMC Products

Addresses EMC countermeasure demand accompanying the higher voltage and higher frequency trends in automotive and industrial equipment. Medium- to long-term demand growth is expected against a backdrop of tightening regulations.

Growth Drivers

  • Continued growth in xEV-related (including HV and PHEV) automotive demand in China and other parts of Asia
  • Strong performance of robotics-related and medical-related industrial demand in other parts of Asia
  • Steady demand for home appliance-related products such as notebook PCs, tablets, and smartphones accompanying the spread of generative AI-equipped models
  • Profitability improvement through optimization of manufacturing overhead costs in China (final year of the three-year plan)
  • Capturing demand for power supply and cooling-related products for high-load servers accompanying expanding infrastructure investment for AI data centers
  • Expanding production capacity as an export base to the US and Europe utilizing other Asian sites such as Vietnam
  • Strengthening sales in new fields such as next-generation vehicles, energy storage, drones, and robots in China

Risks

  • Risk of a decline in final demand and a reversal of front-loaded demand due to fluctuations in US tariff policy in North America
  • Downward price pressure on the entire supply chain due to excessive price competition intensifying in the Chinese EV market
  • Risk of continued weakness in automotive-related demand from European manufacturers in China
  • Foreign exchange risk from fluctuations in the Chinese yuan, Hong Kong dollar, US dollar, etc. (a weaker yuan and Hong Kong dollar are factors that reduce profit)
  • Geopolitical risk and export regulation risk associated with concentrated production at sites in China and Asia
  • Risk of rising energy and raw material prices and increased maritime logistics costs due to tensions in the Middle East
  • Risk of rising interest rates given that approximately 80% of borrowings are at variable interest rates
