GCC

What GCC does

GCC Inc. (株式会社ジーシーシー) is a privately held Japanese IT company founded in 1965 in Maebashi, Gunma Prefecture, specializing in administrative system solutions for local government municipalities. Its core platform is e-SUITEv2, an integrated administrative system suite covering more than 60 business processes including resident information management, tax processing, welfare administration, financial accounting, human resources and payroll, public housing management, nursery school enrollment selection, and school meal management. The platform is offered in both on-premises and Government Cloud editions, with the cloud edition certified for compliance with Japan's Digital Agency standardization requirements and deployed on Oracle Cloud Infrastructure alongside other Government Cloud environments.

The company monetizes through a mix of software licensing, multi-year implementation and system development services, managed IT infrastructure, data center services (operated from its own GCC Data Center opened in 2021), BPO services covering high-volume data entry and document processing, and ongoing maintenance and support contracts. GCC sells directly to municipal governments through its Maebashi headquarters and Tokyo offices (relocated to Nishi-Shinjuku in December 2025), targeting city, ward, town, and village governments nationwide. Over 200 local governments use its 'at home V' public housing management system, and recent standardization migrations include Tomioka City (July 2024), Kokubunji City (January 2025), Kumagaya City (January 2025), and Sumida City (September 2025) — the latter marking the first special-ward standardization migration. Strategic partnerships with Oracle Japan, LINE CLOVA, ESRI Japan, SCSK Minori, and カオナビ extend the platform's capabilities, while the November 2024 acquisition of exus Corporation expanded GCC's technology and information services portfolio.
