Business
CONVUM Ltd. (formerly Myotoku Ltd.) has operated as a specialized vacuum equipment manufacturer for over 50 years since launching its vacuum generator "CONVUM" in 1972. Its main products include Vacuum Generators (Ejector), Vacuum Suction Pads, Pressure Sensors, and Robot Hand Kits, among others, which are supplied for automation equipment and industrial robots at various manufacturing plants. The company has consolidated subsidiaries in South Korea and Thailand in addition to its domestic (Japan) base, targeting manufacturing customers in Japan, South Korea, and Southeast Asia. Development of all products is centrally handled by the domestic parent company, while manufacturing and sales are carried out by each location. The company is listed on the Tokyo Stock Exchange Standard Market.
Business Model
A vertically integrated manufacturing and sales model in which product development is consolidated at the domestic parent company, while manufacturing is handled by facilities in Japan and South Korea. Domestically, the company primarily uses distributors such as Nichiden Co., Ltd. (22.2% of sales) and Daido Corporation (17.2% of sales) as key sales channels, supplying products broadly to the manufacturing industry. The domestic segment accounts for approximately 82% of sales, with the remainder handled by overseas subsidiaries in South Korea and Thailand. The company continuously invests in capital expenditure and R&D (R&D expenses of ¥78 million in FY2025 (ended March 2025)), pursuing a strategy of expanding its revenue base through new product launches and acquisition of new customers.
Company Strengths
Launched the Vacuum Generators (CONVUM) in 1972, and the brand has since become widely recognized throughout the industry. Backed by technology and know-how accumulated over more than 50 years as a specialized manufacturer, the company develops in-house its product lineup including ejectors, suction pads, and pressure sensors. Development of all products is consolidated at the domestic parent company, enabling continuous improvement in quality and functionality.
As of the end of FY2025, total assets stood at ¥6,404 million against total liabilities of ¥363 million, with net assets of ¥6,040 million, maintaining a financial structure that is nearly debt-free. The equity ratio of 93.6% is exceptionally high for a manufacturing company, and the company held cash and cash equivalents of ¥2,253 million. Financial risk is extremely low, and the company is positioned to fund capital expenditures and R&D with its own resources.
The company continues to expand its lineup of robot hands for industrial and collaborative robots. In FY2025, it developed the SGP-H2 hand for handling kraft paper bags, the SGR small hand for bag-type items, and a multi-adapter for collaborative robots, among others. Against the backdrop of demand for labor-saving and automation, inquiries about robot hand-related products have increased, contributing to the acquisition of new customers.
ENVALITH's Perspective
Performance Trend
Over the past five fiscal years, performance peaked in FY2022 (revenue of ¥2,381 million, operating profit of ¥614 million), underwent a substantial correction in FY2023–FY2024, and then bottomed out and turned to a recovery trend in FY2025 with revenue of ¥1,982 million and operating profit of ¥295 million. In Q1 of FY2026 (ending December 2026), revenue reached ¥561 million (up 15.5% year on year), operating profit ¥109 million (up 18.6%), and ordinary profit ¥111 million (up 22.1%), showing acceleration. As external factors, a recovery in demand related to semiconductor manufacturing equipment and expanding investment in labor-saving and automation have provided tailwinds. On the other hand, due to a decrease in valuation difference on available-for-sale securities (down ¥28,775 thousand) and a deterioration in foreign currency translation adjustments (down ¥20,593 thousand), quarterly comprehensive income came to ¥28 million, down 38.5% year on year. The full-year forecast calls for revenue of ¥2,264 million (up 14.3% year on year), operating profit of ¥294 million (flat, ±0.0%), and net income of ¥232 million (down 6.6%), pointing to a revenue increase with profit flat to slightly down.
Growth Strategy
Aiming for sustainable growth through three pillars: expansion of the robot hand business, new product development, and strengthening of overseas operations
Continuing to promote the electrification of suction hands and develop new-material and new-shape suction pads to capture labor-saving and automation demand. In the first quarter of FY2026 (ending March 2026), inquiries for robot hand-related products were strong, and the company is pursuing sales activities centered on new product launches and new customer acquisition.
Signs of recovery in demand for semiconductor manufacturing equipment and maintenance have been confirmed in the Japan and South Korea segments. Increased orders for vacuum equipment and suction pads contributed to results in the first quarter of FY2026 (ending March 2026), and the company aims to expand sales as the recovery gains full momentum.
The South Korea segment saw a sharp recovery in the first quarter of FY2026 (ending March 2026), with operating profit of ¥6,433 thousand (up 649.1% year on year). The Thailand operation continues to introduce products into automotive- and food-related equipment, but operating losses have persisted, making profitability in the Southeast Asian market a key challenge.
