The company has strength in high-precision machining for automotive parts and motor shafts, and was selected as a global supplier by Caterpillar Inc. of the United States in 2005. In 2020, it was also designated a Global Niche Top company certified by the Ministry of Economy, Trade and Industry.

Recent Overview

Net sales and operating profit declined sharply, but a foreign exchange gain of ¥580 million pushed up ordinary profit

For the cumulative nine months of Q3 FY2026 (ending August 2026) (September 2025 to May 2026), net sales were ¥2,749 million (down 33.5% year on year) and operating profit was ¥30 million (down 93.3% year on year), representing a significant deterioration. On the other hand, a foreign exchange gain of ¥580 million recorded under non-operating income lifted ordinary profit to ¥919 million (up 28.5% year on year), and net profit attributable to owners of the parent to ¥609 million (up 27.3% year on year), securing an increase in profit. On the balance sheet, investment securities increased by ¥1,419 million, expanding total assets. Contract liabilities increased by ¥735 million (to ¥1,182 million), suggesting an accumulation of orders ahead of future revenue recognition. The full-year earnings forecast remains unchanged at net sales of ¥5,467 million and operating profit of ¥381 million.

Key Products

product
Centerless Grinder

A high-precision outer-diameter grinder using the centerless method. It has strength in mass-production machining applications such as automotive parts and motor shafts, and is sold globally, mainly in North America, Asia, and Latin America. It is manufactured on a build-to-order basis at the head office plant in Yamagata Prefecture.

product
Internal Grinder

A grinder used for high-precision finishing of the inner diameter of workpieces. Together with the Centerless Grinder, it forms one of the company's core product lines, and is sold to precision parts manufacturers both in Japan and overseas.

product
Grinder Peripheral Equipment

Automation peripheral equipment such as loaders and unloaders that accompany the main grinder unit. The company responds to customers' production line automation needs by providing these as an integrated system, thereby increasing added value.

service
Parts & After-Sales Service

Sale of replacement parts and provision of maintenance services for previously delivered grinders. This is a stable revenue source that is relatively unaffected by economic fluctuations, accounting for approximately 19% of net sales in the previous fiscal year.

Growth Drivers

  • High level of overseas demand: Despite an uncertain international situation, overseas demand has remained at a high level, continuing to support sales through overseas shipments
  • Accumulation of contract liabilities: Contract liabilities at the end of Q3 increased significantly to ¥1,182 million (up ¥735 million from the end of the previous fiscal year), which is expected to translate into future revenue recognition
  • Profit supplementation through foreign exchange gains: Against a backdrop of yen depreciation, a foreign exchange gain of ¥580 million was recorded, offsetting the sharp decline in operating profit at the ordinary profit stage
  • Increase in the value of investment securities: Investment securities expanded to ¥3,251 million (up ¥1,419 million from the end of the previous fiscal year), strengthening the financial base
  • Continued North American demand based on selection as a global supplier by Caterpillar Inc.
  • Promotion of company-wide cost reduction activities: Gross profit margin was maintained at 37.3%, and SG&A expenses were reduced to ¥993 million (down ¥84 million year on year)

Risks

  • Sharp decline in net sales: Cumulative Q3 net sales fell sharply by 33.5% year on year to ¥2,749 million, and achieving the full-year forecast of ¥5,467 million requires recording ¥2,718 million in sales in Q4
  • Extremely low level of operating profit: Cumulative Q3 operating profit was only ¥30 million (operating profit margin of 1.1%), and achieving the full-year forecast of ¥381 million requires ¥351 million in operating profit in Q4
  • Foreign exchange fluctuation risk: Ordinary profit is heavily dependent on a foreign exchange gain of ¥580 million, meaning that changes in exchange rate trends directly affect business performance
  • U.S. trade policy (tariff) trends: The risk of impact on sales to North America and Latin America, key export destinations, continues
  • Sluggish domestic demand: Domestic machine tool demand remains weak, making a recovery in domestic sales difficult to anticipate
  • Difficulty in procuring materials due to the situation in the Middle East: The situation in the Middle East has caused difficulty in procuring some materials, posing a risk to manufacturing and delivery schedules
  • Dependence on specific customers: Risk of customer concentration due to sales concentration among top customers
  • Rising raw material costs: Rising raw material costs push up manufacturing costs, posing a risk of pressure on profitability
