Business
Lasa Corporation is a specialty trading company founded in 1939, comprising a total of four companies: the company itself, two consolidated subsidiaries, and one affiliate. It operates six businesses: resources/metal materials (import/export of mineral products such as zircon sand), industrial machinery/construction machinery (sales and maintenance of conveying equipment and construction machinery), environmental equipment (high-pressure pumps and water granulation equipment), chemical products (synthetic resins and chemical products), plant/facility construction (piping and rotating machinery construction work), and real estate leasing. Its major customers span a wide range of industrial fields, including steelmaking, refining, electric power, chemicals, semiconductors, automobiles, and government agencies, and it positions itself as a value-creating company supporting the maintenance and development of social infrastructure.
Business Model
Based on exclusive distribution agreements with leading overseas manufacturers (Ailuka, Taiheiyo Kiko, Putzmeister, etc.), the company adopts a composite revenue model that combines equipment sales with parts supply, maintenance, and servicing. In particular, the Industrial & Construction Machinery segment has a structure in which demand for parts and maintenance accumulates steadily, while Real Estate Leasing (profit margin of 79.2%) supplements the stable earnings base.
Company Strengths
Since introducing Warman pumps to Japan in 1959, the company has maintained a top-class share in corrosion- and abrasion-resistant pumps for over 60 years. With a track record of supply to a wide range of industries including steelmaking, smelting, electric power, chemicals, and semiconductors, its products' ease of disassembly and assembly—enabling on-site maintenance—matches customers' needs for extending equipment life, generating continuous demand for parts and maintenance.
The company has concluded long-term exclusive distribution agreements with multiple leading overseas manufacturers, including Ailuka (zircon sand), Taiheiyo Kiko (Warman pumps), and Putzmeister (high-pressure piston pumps). Including contracts extended through 2029, it has secured stable product procurement and exclusive sales rights, building a procurement and sales network that competitors cannot easily replicate in a short period.
The "Rasa System," a granulated blast furnace slag production facility that granulates molten slag from steelworks using high-pressure water, is the company's proprietary technology, with a track record of numerous deliveries to steelworks both in Japan and overseas. It is recognized as an environmental technology that contributes to reducing hydrogen sulfide emissions into the atmosphere and to resource recycling as a raw material for cement, serving as a stable revenue source through ongoing refurbishment and improvement projects for existing facilities.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥31,329 million in FY2022 (ended March 2022), then declined for four consecutive periods to ¥26,568 million in FY2025 (ended March 2025), before rebounding to ¥28,201 million in FY2026 (ending March 2026), up 6.1% year on year. Operating profit rose from ¥2,551 million in FY2022 (ended March 2022) to ¥2,958 million in FY2026 (ending March 2026), marking the highest level in the past five periods, and net income also reached its highest level over the same span at ¥2,378 million. The operating margin on sales reached 10.5%. The main earnings drivers were a substantial increase in revenue related to environmental equipment and robust demand for parts and maintenance related to industrial and construction machinery, with a favorable external factor being the steady capital expenditure environment among domestic companies.
Growth Strategy
Under the medium-term management plan "Step Forward Rasa 2027," the company aims to achieve net sales of ¥31,500 million and operating profit of ¥2,900 million in FY2028 (ending March 2028)
The company is advancing initiatives in new and growth fields, including the development of new resource-related materials such as rare earths and raw materials for electronic components, the expansion of pump adoption for wet methane fermentation biogas power generation plants for food waste recycling, and the supply of construction machinery for power transmission grid development aimed at achieving a decarbonized society.
The company is capturing demand trends related to the aging of sewerage facilities (stock management) and the movement toward public-private partnerships (Water PPP) by strengthening its proposals for pump diagnosis, inspection, and maintenance optimization. It is also expanding demand for the Multi-purpose Mobile Pump Unit "SUPER BETSY" among both government and private-sector customers.
Building on its track record with the Rasa System (Granulated Slag Production Equipment) for steelworks, the company is working to expand into the non-ferrous metals industry market, while pursuing equipment compactification and reduced system load through combination with high-performance chemicals. It is also promoting the expansion of belt cleaner scrapers into other steelworks as well as the cement, electric power, and non-ferrous metals industries.
The company is strengthening sales into Southeast Asia using its overseas representative offices (Singapore Branch and Shanghai Representative Office) as information hubs. It continues to generate new demand by strengthening relationships with the overseas local subsidiaries of domestic business partners, as well as to develop new domestic demand through prototype proposals based on marketing efforts.
The consolidated management targets for FY2028 (ending March 2028) are net sales of ¥31,500 million, operating profit of ¥2,900 million, ordinary profit of ¥3,150 million, and profit attributable to owners of parent of ¥2,300 million. In the first year (FY2026, ending March 2026), all indicators exceeded the plan and were achieved. The management indicator targets of ROE of 10% or more and operating margin of 9% or more have also been achieved.
