What FUJI SUBSURFACE INFORMATION does

FUJI SUBSURFACE INFORMATION is a Tokyo-headquartered, Veolia Group-affiliated B2G services company that provides maintenance, inspection, and digital management solutions for Japan's water and sewerage infrastructure. Founded in 1970 with 1,001–5,000 employees, the company operates four integrated business lines: (i) water supply pipeline and facility maintenance (leak detection, measurement, inspection, consulting, pipeline drawings, underground detection); (ii) sewerage pipeline and facility maintenance (screening, unidentified water investigation, cavity surveys); (iii) water/sewerage meter reading, billing and customer service operations; and (iv) DX/ICT solutions delivered through the proprietary Fmap platform. Services are delivered through 11 branch offices covering Hokkaido, Tohoku, Tokyo, Hokuriku, Nagoya, Osaka, Okayama, Hiroshima and Kyushu, providing nationwide coverage to municipal water utilities and sewerage operators.

The company's core technology stack combines a domain-specific GIS suite (FmapBase, FmapFile, FmapCalc, FmapMafin, FmapMobile) with two differentiated AI/automation products: FmapMIRAI, which uses historical repair, accident and pipe specification data to numerically predict pipe deterioration scores; and Archimedes (アルキメデス), an autonomous in-pipe drone that performs sewer screening inspections without requiring personnel to enter manholes. A cloud-based portable water monitoring system rounds out the offering, enabling real-time web-based visibility into water facility data. The company holds ISO 9001 (QMS, since 2012), ISO 27001 (ISMS, since 2008), and Privacy Mark certifications across all branches, and maintains a data asset accumulated since 1970 that underpins its AI modeling.

Revenue mechanics are dominated by long-duration, contract-based engagements with municipal governments. The traditional maintenance business operates on managed-services contracts (leak detection surveys, meter reading, billing) procured through public tendering and direct engagement with municipal waterworks departments. A second, higher-value revenue stream is being built around Water PPP (Public-Private Partnership) Level 3.5 comprehensive municipal delegations, where the company participates in joint ventures (Hayama Town 下水道ウォーターパワーPPP, 10-year/¥1.83B; Joyo City 水道事業及び下水道事業包括的民間委託, 10-year/¥3.8B) as a member alongside Veolia Genets, Tokyu Construction, Chuo Sekkei, West Japan Railway, and other partners. The Veolia Group affiliation provides distribution reach, international best-practice transfer, and access to PPP bidding consortiums, while the Fmap software portfolio introduces a recurring/hybrid revenue layer through cloud, standalone, and web system deployments.
