Business Details

A core domestic segment providing an integrated three-process offering consisting of Precision Press Processing (including mold design and manufacturing), Precious Metal Surface Treatment Processing (gold, palladium-nickel, tin plating, etc.), and Insert Molding Processing. In February 2026, the company absorbed its wholly owned subsidiary Meiou Kasei Co., Ltd. through a merger, further strengthening its integrated processing structure covering pressing, plating, and insert molding. Main customers are connector manufacturers and others, supplying high value-added components for advanced products such as automotive (ADAS, in-vehicle equipment), industrial equipment (AI servers, semiconductor manufacturing equipment), and smartphones. This is the flagship segment, accounting for approximately 74% of consolidated net sales.

Recent Overview

Both net sales and profit increased substantially year on year; integrated structure strengthened through absorption of Meiou Kasei

For the cumulative third quarter of FY2026 (ending March 2026) (August 2025 to April 2026), the Japan segment recorded net sales of ¥8,190 million (up 51.6% year on year) and segment profit of ¥1,270 million (up 129.6% year on year), representing substantial increases in both revenue and profit. This was primarily driven by expanded orders for AI server, semiconductor-related, and automotive ADAS applications. Effective February 1, 2026, the company absorbed its wholly owned subsidiary Meiou Kasei Co., Ltd. through a merger, integrating insert molding technology and equipment into the parent company. In addition, from the first quarter, the company changed its depreciation method from the declining-balance method to the straight-line method, resulting in an accounting impact that increased operating income by ¥111 million for the cumulative third quarter.

Key Products

product
Precision Press Processing

Provides integrated support from mold design and manufacturing to mass-production press processing. Supplies precision components for advanced products such as automotive ADAS-related applications, AI server-related applications, and smartphones.

product
Precious Metal Surface Treatment Processing

Promotes advancement of fine plating technology, improving production capacity and quality stability through the operation of new plating lines. Provides high value-added plating for semiconductor-related and communication-related components.

product
Insert Molding Processing

Integrated technology and equipment through the absorption-type merger with Meiou Kasei Co., Ltd. Handles a wide range of products including connector components, switch components, and capacitor components, maximizing added value through an integrated order-receiving structure combining pressing, plating, and molding.

Growth Drivers

  • Expansion trend in the industrial equipment field driven by generative AI and data center-related demand
  • Continued firm demand related to automotive ADAS applications
  • Expanding orders in the semiconductor-related field
  • Steady progress in the communication-related field for PCs and tablets
  • Improved production capacity and quality stability through operation of new plating lines
  • Strengthened integrated processing structure covering pressing, plating, and insert molding through the absorption-type merger with Meiou Kasei Co., Ltd.
  • Advancement of fine plating technology and mold manufacturing technology
  • Improved productivity and competitiveness through automation and efficiency improvements in manufacturing processes
  • Appropriate pass-through of cost increases such as raw material prices

Risks

  • Cost pressure from persistently high raw material prices (precious metals such as potassium gold cyanide)
  • Demand fluctuations due to US tariff policy and geopolitical risks (Middle East situation, etc.)
  • Risk of spillover effects on electronic component demand due to sluggish Chinese economic conditions and delayed recovery in domestic demand
  • Unstable order intake due to variation in demand by model, such as for smartphones
  • Profit pressure from rising prices and increasing labor costs
  • Accounting estimation uncertainty associated with the change in depreciation method (from declining-balance to straight-line)
  • Feasibility of realizing integration costs and operational efficiency following the absorption-type merger with Meiou Kasei
