Business
Mitsuchi Corporation was founded in 1963, with its core business being the manufacture and sale of automotive custom fasteners (custom-order fastening hardware) built on cold forging technology as its core competence. The company handles a wide range of vehicle body functional components, including Seat Components, Window Regulator Components, Lock Components, and Engine Components, with its primary customers being tier-one automotive parts manufacturers. In addition to its three domestic subsidiaries (Mitsuchi Seisakusho, Mitsuchi Buhin Kogyo, and Sosei Engineering), the company has built a global structure with overseas operations in Thailand, the United States, China, and India. It is listed on the TSE Standard Market and the Nagoya Stock Exchange Main Market. Consolidated net sales for FY2025 (ended June 2025) were ¥12,412 million.
Business Model
The company manufactures custom fasteners to order based on specifications from customers (automotive parts primary manufacturers), securing cost competitiveness by leveraging the characteristics of cold forging—high-speed productivity, material savings, and high strength. Domestic core plants (Mitsuchi Seisakusho and Mitsuchi Buhin Kogyo) serve as the core of production, while overseas sites in Thailand, the United States, China, and India respond to local procurement needs. The Japan Segment accounts for approximately 67% of net sales, and the Thailand Segment (net sales of ¥2,567 million, operating margin of 12.9%) underpins the group's profitability.
Company Strengths
Since beginning cold forging operations in 1974, the company has accumulated over 50 years of technical expertise and has obtained quality certifications such as ISO9001 and IATF16949 at domestic and overseas sites. Leveraging cold forging's characteristics of high-speed production, resource efficiency, and high strength, the company continues to take on technical challenges for difficult-to-process products. R&D expenses for the fiscal year under review amounted to ¥23,416 thousand, with expansion into new fields such as hydrogen piping connectors.
Thai Mitchi Corporation Ltd. achieved net sales of ¥2,567 million, operating profit of ¥332 million, and an operating margin of 12.9% in FY2025 (ending June 2025), making it the group's only overseas base with stable profitability. The order backlog increased 24.0% year on year to ¥201,250 thousand, and the launch of new orders backed by large-scale capital investment is also underway.
The equity ratio as of the end of FY2025 (ending June 2025) remained at a high level of 60.8% (60.7% in the previous fiscal year). Net assets stood at ¥9,647 million against total assets of ¥15,858 million. Cash and cash equivalents amounted to ¥3,988 million, securing ample liquidity on hand, which underpins the financial basis for capital investment and overseas expansion under the medium-term management plan.
ENVALITH's Perspective
Performance Trend
Cumulative sales for the nine months of the third quarter of FY2026 (ending March 2026) were ¥9,264 million (down 0.4% year-on-year), continuing the flat trend. Over the past five fiscal periods, sales have remained in the range of ¥12,000 million to ¥13,800 million, and the company has not achieved a growth trajectory. Operating profit fell sharply to ¥48 million (down 59.1% year-on-year). While the cost of sales ratio remained flat at 83.3% (versus 83.3% in the same period last year), the absolute amount of gross profit declined, and fixed costs could not be fully absorbed. In terms of the external environment, year-on-year declines in automobile production volumes in Japan and Southeast Asia, a decline in the market share of Japanese manufacturers in China, and tariff measures and rising raw material prices weighed on earnings. On the other hand, resilient production volumes in the United States and foreign exchange translation effects from yen depreciation contributed positively. Comprehensive income rose significantly to ¥819 million (up 93.8% year-on-year), but this was due to an increase of ¥528 million in the foreign currency translation adjustment account, and does not indicate an improvement in the underlying business performance.
Growth Strategy
Four-pillar strategy under "Vision 24," targeting net sales of ¥14,000 million and an operating margin of 5.0% for FY2027 (ending June 2027)
Advancing the launch of newly awarded products through large-scale capital investment at the Thailand base, acquisition of new core business relationships in the United States, and preparation for full-scale operation of the Indian subsidiary established in June 2025. Thailand has delivered results, with net sales up 10.2% and profit up 20.3% year on year, but the United States requires urgent improvement as operating losses have widened despite higher sales.
Promoting cost reduction activities such as lowering consumable tool costs and improving labor productivity, along with rationalization of manufacturing expenses. Selling, general and administrative expenses were reduced from ¥1,437 million in the same period of the previous year to ¥1,403 million, but this was insufficient to offset the decline in gross profit (down ¥105 million), resulting in a significant decrease in operating profit.
Promoting the expansion of applications for the in-house developed special fastener "Quick Series" and the acquisition of new customers for non-automotive components. However, net sales of non-automotive components for the cumulative third quarter were ¥1,387 million (down 13.3% year on year), continuing to struggle in contrast to automotive components (up 2.3% year on year).
Promoting DX through the operation of a new core system and rationalization of indirect operations. While some effect has been seen in the reduction of SG&A expenses (down ¥34 million year on year), it remains difficult at this stage to quantitatively assess the effect relative to the scale of the business.
