## Press Release Information
**Title:** AI Collaboration Reduces 7-Hour Task to 5 Minutes; Minna no Banko Adopts Google Cloud’s Gemini Enterprise
**Company:** Minna no Banko, Ltd.
**Main Text:**
Minna no Banko, Ltd. (President & CEO: Kenichi Nagayoshi) has introduced 'Gemini Enterprise,' an enterprise-grade generative AI platform from Google Cloud, for all its employees.
In a pioneering business reform project for Anti-Money Laundering (AML) and financial crime countermeasures, the bank utilized 'Gemini' to complete complex administrative tasks that previously took 7 hours in just 5 minutes with a single click—an AI-human collaboration. This resulted in a remarkable 47% reduction in total labor time for that specific business area (as of December 2025 performance and estimates). Following this success, the bank decided to roll out 'Gemini Enterprise' across the entire organization.
**Background**
Minna no Banko faced the challenge of increasing administrative burdens related to AML and financial crime countermeasures due to a growing number of accounts and transactions. In response, an internal project team leveraged Google's generative AI model, 'Gemini.' Employees with no prior programming experience received coding assistance from the AI to develop internal programs using Excel Macros (VBA) and Python, improving productivity in a short period.
Consequently, processes such as 'aggregate table creation,' 'folder organization,' 'report output,' and 'report writing'—which were previously handled manually by multiple people—were integrated into a 'one-click' workflow using RPA tools and other technologies. This reduced a 7-hour task to 5 minutes, simultaneously achieving significant time savings (47% overall) and the elimination of human errors inherent in manual work.
To sublimate this success from specific tasks into a company-wide culture, the bank decided to officially adopt 'Gemini Enterprise.'

**Future Outlook**
As a digital bank, Minna no Banko aims for highly efficient services where complex back-office tasks are systematized, allowing staff to complete duties with just a 'one-click.' Moving forward, the bank will leverage Gemini Enterprise features to utilize proprietary AI agents internally. This will standardize an environment where AI powerfully supports human task execution, driving further improvements in productivity and quality.
The productivity gains from AI collaboration will be used to realize the bank's mission: 'Connecting Everyone with Value.' This will shift human capital into higher value-added areas, accelerating the provision of innovative services and the creation of innovation.
