Business
OSG Corporation was established in August 1970 (marking its 55th anniversary). Centered on the manufacturing and sale of water-related equipment such as Electrolyzed Hydrogen Water Generators and Water Purifiers, the company is organized into four segments: the Maintenance Business, the HOD (Home/Office Delivery) Business, and the FOOD Business. Operating as a group that includes 18 subsidiaries, it has expanded across 11 domestic locations nationwide as well as into Asian countries including China and India. Positioning social issues such as plastic waste and heatstroke prevention as business opportunities, the company is pursuing both the deepening of its water-related businesses and the development of new markets in the food sector in parallel, under a long-term vision of becoming a "100-year company."
Business Model
The Maintenance Business (operating margin of 18.9%), which generates recurring revenue through on-site maintenance and cartridge replacement after the sale of water-related equipment, serves as the core profit pillar. The HOD Business builds up stock revenue from Bottled Water Delivery Service through the Area License Chain format. The FOOD Business also adds royalty income through franchise expansion. A distinguishing feature is the multi-layered recurring structure spanning product sales → maintenance → delivery/franchise revenue.
Company Strengths
The company possesses an on-site maintenance system that leverages a customer database built up over 55 years since its founding. In FY2026 (ending March 2026), the Maintenance Business achieved net sales of ¥2,075 million, operating profit of ¥393 million, and an operating margin of 18.9%. Stable recurring revenue from the existing customer base underpins the earnings of the entire group.
The company installed free water stations at the Osaka-Kansai Expo venue, demonstrating a reduction of approximately 50% in on-site waste generation compared to initial projections. By the close of the Expo, the number of water dispensing uses had surpassed 12 million. Building on this track record, the company has been accumulating advance orders from municipalities and school facilities, and is progressively turning the social demand for measures against plastic waste and heatstroke prevention into concrete business opportunities.
The company's in-house technology development division (Edison Division) works in coordination with the product development department of its subsidiary OSG Water Tech Co., Ltd., establishing an integrated system covering everything from planning and development to manufacturing, sales, and maintenance. This structure allows customer feedback to be directly reflected in product development, and R&D expenses for FY2026 (ending March 2026) totaled ¥45 million. The company also holds the distinction of being the only company in its industry to have won the Grand Prize for ten consecutive years at the "Hito Suzumi Award" heatstroke-prevention awareness campaign.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥9,868 million in FY2022, declined to ¥7,896 million by FY2024, then recovered gradually to ¥7,930 million in FY2025 and ¥8,185 million in FY2026. Operating profit plunged from ¥1,141 million in FY2022 to ¥134 million in FY2025, showing signs of bottoming out with a recovery to ¥208 million in FY2026. However, in Q1 of FY2027 (ending January 2027), revenue was ¥1,983 million (down 1.3% year on year) and operating profit was ¥38 million (down 30.9% year on year), marking a renewed profit decline. The main cause was the reversal of temporary revenue and profit from equipment and materials exports in the FOOD Business recorded in the same quarter of the previous year; while this does not reflect a structural deterioration, achieving the full-year forecast (operating profit of ¥500 million) will require a substantial recovery over the remaining three quarters. The Maintenance Business saw a profit decline due to increased costs from human capital investment, but maintained stable revenue.
Growth Strategy
A growth strategy built on two pillars: capturing demand tied to solving social issues, and improving profitability in the FOOD Business
Building on the track record of Water Stations at the Osaka-Kansai Expo and awards received for SDGs and heat stroke prevention initiatives, inquiries from municipalities, schools, and public facilities nationwide have increased substantially. The company has achieved certain results in the form of advance orders, and the mandatory heat stroke countermeasures introduced under the revised Industrial Safety and Health Act, effective June 2025, are functioning as an external tailwind.
Amid rising demand for safe and reliable drinking water driven by water quality concerns such as PFAS, the company is expanding a subscription-based model for household Water Purifiers. Progress continued in Q1, and this is also expected to contribute to future expansion of the customer base for the Maintenance Business.
Through the closure of unprofitable stores and restructuring of the profit structure, the scale of losses has narrowed substantially. Sales per directly-operated store improved to 106.2% year-on-year, and management has stated that progress toward profitability within the current fiscal year is proceeding as planned.
Efforts to capture inbound demand, together with ongoing new product development and social media utilization initiatives, have proven effective, with Q1 progress exceeding plan. Two new stores are planned to open within the current fiscal year, further strengthening the foundation for growth.
A three-store framework serving as a model for franchise expansion has been established in Shanghai. The brand has been selected for three consecutive years (2023, 2024, and 2025) as one of the "POP Shanghai 100" (a list of 100 notable Shanghai stores). Going forward, the company will promote franchise expansion across all of China, concentrating management resources on markets with significant growth opportunities.
The new factory, which began operations in August 2024, has led to upfront fixed cost burdens, but production capacity has improved substantially. Alongside strengthening brand power by leveraging the 70th anniversary (next year) of Ganso Goban Kagurazaka Main Store, the company is expanding sales channels centered on the hotel and restaurant market.
