Mizuho Financial Group, Inc. (President & Group CEO: Masahiro Kihara) announces the development and full-scale rollout of "Mizuho RM Studio", an integrated AI application designed to support the proposal operations of Relationship Managers (RM) in charge of corporate sales at its subsidiary, Mizuho Bank, Ltd. (President & CEO: Katsuhiko Kato).
"Mizuho RM Studio" utilizes AI to connect the entire process from customer understanding to proposal preparation and post-meeting reflection. By converting the often personalized tacit knowledge of corporate sales into reusable explicit knowledge as an "organizational asset", it elevates overall proposal capabilities and fosters the development of junior RMs. Furthermore, by reducing pre-meeting preparation time by approximately 50% and redirecting the saved time toward dialogue with customers, Mizuho aims to increase the frequency of dialogue with corporate clients by about three times while deepening the precision and depth of proposals.
Mizuho plans to expand the scope of users for "Mizuho RM Studio" by the end of fiscal year 2026, aiming to deploy it to all of Mizuho Bank's approximately 3,500 corporate RMs.
■ Background
Entering 2026, the use of AI is expanding beyond a mere Q&A tool to a "cowork" model, where it collaborates with humans in the same space while creating deliverables. Accordingly, the ability of AI to inherit information per customer or project and leave deliverables that humans can verify and modify midway is becoming an important direction for future AI utilization.
On the other hand, in the conventional frontlines of corporate RMs, the depth of customer understanding and proposal quality have structurally depended heavily on the individual experience and skills of the person in charge, making it difficult for knowledge to be accumulated and utilized across the organization. As a result, each person had to independently handle a series of tasks, including before and after the proposal, requiring significant time for preparation. Under these circumstances, fundamentally reviewing this structure was necessary to continuously improve the quality of customer dialogue and proposals.
To address these challenges, Mizuho has built the integrated AI application "Mizuho RM Studio" as a mechanism where AI collaborates across the entire business flow of corporate RMs.
■ Overview of the Initiative
"Mizuho RM Studio" is a business support application developed in-house to automatically generate draft proposal scenarios and materials via an AI agent, ensuring the provision of high-quality services to customers even amidst personnel changes due to a declining working population.
This application supports the sales activities of corporate RMs from two perspectives: "sophistication of the sales process" and "systematic capitalization of sales knowledge."
Sophistication of the Sales Process: End-to-end support from customer understanding to proposals and reflections
Currently, "Mizuho RM Studio" features the following functions:
- External information gathering
- Support for customer understanding
- Structuring proposal issues
- Automated proposal material creation
- Post-meeting content reflection
Specifically, based on internal customer overview documents, securities reports, medium-term management plans, activity records (meeting logs), as well as contact history and project information accumulated in the CRM, and product information handled by Mizuho, the AI agent multifaceted organizes each customer's business details, management challenges, and industry trends to support the structuring of proposal issues and storylines.
Particularly in the automated proposal material generation function, Mizuho is advancing functional sophistication while incorporating external products. For slide creation, Mizuho's internally developed "Mizuho Slide Gene
