What G-gen does

G-gen (株式会社G-gen, pronounced "ji-jen") is a Tokyo-headquartered cloud services integrator and Google Cloud Premier Partner serving Japanese enterprises, government agencies, and educational institutions. Formed in August 2021 through the merger of two Google Cloud Premier Partners — Top Gate (established July 2006) and the original G-gen (established August 2021) — the company is a subsidiary of AWS-specialized integrator Serverworks Co., Ltd. and operates as a joint venture with Newberry Global Japan. The firm is led by Representative Director and CEO Takashi Hashiba (羽柴 孝), with CTO Yuma Sugimura, CRO Yoshikazu Kurosu, and other executive officers overseeing cloud solutions, sales, and business development functions.

G-gen's core offering bundles Google Cloud and Google Workspace billing agency (with a 3% discount off Google standard pricing), professional services (migration, security assessment, dedicated professional engagements, certified training, CCoE companion support), generative AI implementation services (Workshops, PoC packages, Gemini Enterprise verification), and a digital product development practice covering consulting, UX/UI design, web application development, and cloud-native infrastructure. Underlying technology spans the full Google Cloud portfolio — Cloud Run, BigQuery, Vertex AI / Gemini Enterprise Agent Platform, GKE, Cloud Functions, Cloud SQL, Looker, Cloud IAP, Cloud NGFW, Dataplex, Pub/Sub, and Colab Enterprise — with specialized packages for municipality Local Breakout connectivity (LGWAN to Google Workspace) and disaster-response drone imagery analysis. The company reports 500+ Google Cloud certifications and 1,300+ supported client engagements.

The business model combines recurring resale margin on Google Cloud and Workspace consumption with project-based professional services and certified training revenue. Distribution is direct enterprise field sales supported by a content-led go-to-market — most prominently the G-gen Tech Blog (667+ Google Cloud articles) — alongside webinars, partner events (CCoE Summit, Gemini at Work), paid search, referrals, and the Google Cloud Marketplace private-offer channel. All services are delivered within Japan, with multi-cloud capabilities supplied through the Serverworks group (AWS) and Newberry Global Japan for cross-cloud strategy engagements. Notable customers include Kodansha, Kobe City Healthcare Corporation, Aerosense, Ashikaga City, Digital Agency, Nagaoka University of Technology, Kirin Holdings, Workman, and LIFULL.
