In January 2026, Sompo Japan Insurance introduced Gemini Enterprise as a PoC for approximately 20,000 employees across the company. Within about six months, it raised the weekly active user rate to approximately 80% and advanced adoption through an operating model and governance framework designed to ensure proper use.
Sompo Japan Insurance introduced Gemini Enterprise across the company, initially focusing on promoting use through integration with Gemini Notebook. After implementation, it set 3 goals that prioritised having more employees use the service and ensuring that it was used properly, rather than focusing solely on stable operations as before.
By establishing visualisation and governance mechanisms, the company tracked DAU, WAU, usage of official notebooks and agents, and departmental adoption rates, and used data to assess the impact of promotional efforts at study sessions and events. It also introduced measures to prevent disruptions by using alerts based on Cloud Monitoring and threshold detection.
In May 2026, the company made custom agent creation and sharing available to employees, and developed an in-house system that consolidated the agent list in BigQuery and automatically monitored deviations from the rules. This achieved a balance between citizen development and governance, with DAU exceeding 50% and WAU reaching approximately 80%.
The company views generative AI as business infrastructure and is expanding its use across departments. The number of employees driving AI adoption is increasing and study sessions are becoming more active, with further acceleration of citizen development expected.
