- uSonar Co., Ltd. (Ticker: 431A.T) is a Japan-based provider of database marketing and corporate data integration solutions that enables B2B sales and marketing organizations to centralize, enrich, and activate customer data for targeted outreach and performance measurement. Founded in 1990 and headquartered in Tokyo at Tokyo Opera City, 3-20-2 Nishi-Shinjuku, Shinjuku-ku, the company operates primarily in Japan and serves a broad range of industries through cloud-based software and data services.
The company’s core offerings revolve around its proprietary corporate database “LBC,” which covers more than 12.5 million business locations across Japan and provides over 120 attribute fields including corporate group relationships, industry classification, sales, profit, and employee counts. uSonar leverages LBC as the foundation for its flagship customer data integration platform “uSonar,” which performs data cleansing, deduplication (name matching), enrichment, and white-space analysis to help clients build accurate, unified customer master data and identify untapped prospects. Complementary products and services include: “PlanSonar,” a management strategy platform that supports corporate planning and market visualization; “mSonar,” a mobile and web application for corporate information lookup and business card management; “Registration Sonar,” a tool for downloading official corporate registration data; and specialized solutions for anti-social force screening, sales list creation, and ABM (account-based marketing) enablement. The company’s solutions integrate with major sales and marketing systems such as Salesforce and other SFA/CRM/MA platforms, and are positioned as an information infrastructure for sales, marketing, and management functions across enterprises.
In recent strategic developments, uSonar announced a business alliance in August 2026 with Uzabase, Inc., the operator of the “Speeda” economic information platform, to create an end-to-end support framework spanning targeting, execution, and effect verification in sales and marketing. Under this partnership, uSonar focuses on customer data integration, enrichment, and high-precision target list creation using its LBC-based services, while Uzabase supports campaign design, execution, and performance measurement through its Speeda AI Agent and related offerings; the companies also plan to explore mutual agency sales to expand joint solutions. In addition, uSonar has pursued collaborations to extend its data utilization capabilities, including a 2025 partnership with Persol Business Process Design to deliver data-usage consulting and integrated sales productivity solutions that combine uSonar’s corporate database with Persol’s process design and generative AI capabilities. The company also previously entered into a business alliance in December 2024 with Grand Central to develop an “Intent Sales BPO Package Plan” that applies PlanSonar data to intent-driven targeting for more efficient sales promotion.
uSonar is listed on the Tokyo Stock Exchange Growth Market under securities code 431A and reports as a non-consolidated entity. Its shareholder base includes founder Nami Fukutomi alongside strategic and institutional investors such as Mitsui & Co. Principal Investments and the Development Bank of Japan. The company’s business model centers on subscription and usage-based cloud services that help clients improve sales accuracy, reduce data management workload, and enable data-driven go-to-market strategies across Japan’s B2B landscape.
