Business
RSC Corporation, founded in 1971, is a comprehensive building management service company listed on the Standard Market of the Tokyo Stock Exchange. It consists of two segments: the Comprehensive Building Management Service Business (approximately 92% of revenue), which provides integrated Security Guard Services, Cleaning Services, Office Services, and facility management to government offices, office buildings, hotels, hospitals, commercial facilities, and other clients; and the Human Resources Service Business, which handles Staffing Dispatch Business and Fee-Charging Employment Placement Business. The company has four consolidated subsidiaries (RSC Chubu, Yuwa Shoko, Clean Force, and RSC Security) and one equity-method affiliate, and operates primarily in the Tokyo metropolitan area, expanding into the Chubu and Kansai regions among others. With Sunshine City as a major client, it is a social infrastructure-type service company that captures demand from urban redevelopment and large-scale events.
Business Model
Revenue consists of two forms: "annual contracts" and "temporary contracts." Annual contracts represent stock-type revenue from continuous service provision such as security, cleaning, and facility management, forming a stable sales base. Temporary contracts are one-off projects such as event security, special cleaning, and renovation work, bringing additional revenue during large-scale events. As this is a labor-intensive business, personnel expenses are the main cost, and promoting price pass-through and optimizing staff allocation are key to improving profit margins.
Company Strengths
The company has been contracted to manage Sunshine City since its opening in 1978, and even in FY2026 (ending March 2026) this facility accounts for 16.3% of net sales (equivalent to ¥1,344 million on a ¥1,343,978 million basis). The comprehensive management system providing security, cleaning, and facility management in an integrated manner contributes to reducing clients' management costs and standardizing quality, forming the foundation for long-term continuous contracts.
The company acquired all shares of Yuwa Shoko Co., Ltd. in February 2023 and all shares of Clean Force Co., Ltd. in January 2025, strengthening its service supply capacity in the cleaning and construction domains. In September 2025, it newly established RSC Security Co., Ltd., specializing in Type 2 Security Guard Services, building capabilities for traffic control and crowd control security. The company continues to steadily expand its business foundation through a combination of M&A and new company establishment.
In November 2025, the company entered into a capital and business alliance agreement with SoftBank Robotics Corp., beginning joint development of next-generation security solutions combining AI and robotics technology with the company's own hospitality-oriented security capabilities. At
ENVALITH's Perspective
Performance Trend
Net sales achieved four consecutive periods of growth, rising from ¥5,743 million in FY2022 (ended March 2022) to ¥8,845 million in FY2025 (ended March 2025), but turned to a decline for the first time in FY2026 (ending March 2026), falling to ¥8,232 million (down 6.9% year on year). The main cause was a rebound decline from a large-scale anniversary event project in the Human Resources Service Business (down 66.3% year on year), while the Comprehensive Building Management Service Business remained solid, up 10.0% year on year. Operating profit fell sharply to ¥217 million (down 27.8% year on year), and net income attributable to owners of parent declined to ¥140 million (down 25.1% year on year). The operating margin stood at 2.6%, the lowest level in the past five fiscal years. External factors—a declining working-age population due to the falling birthrate and aging population, wage increase pressures, and soaring construction material prices—are compressing profit margins. For FY2027 (ending March 2027), the company forecasts net sales of ¥8,392 million (+1.9%), but expects operating profit to decline further to ¥117 million (down 46.2%) due to upfront growth investments.
