Yoshidumi Information Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Harumichi Akita; hereinafter "Yoshidumi Information"), a Google Workspace Premier Partner (Service / Co-Sell), is pleased to announce that it has supported Japan Lifeline Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and CEO: Keisuke Suzuki; hereinafter "Japan Lifeline"), a medical company engaged in the import, manufacture, and sale of medical devices primarily in the cardiovascular field, in the company-wide deployment of the generative AI service "Google Workspace with Gemini" through its hands-on support program, "AI Driven Premium." This support has promoted spontaneous AI utilization in the field, realizing company-wide operational improvements and an update to corporate culture.

Background and Challenges of Implementation Japan Lifeline foresaw that the use of generative AI would become essential in a field where high levels of safety are required. In an industry where information leakage risks and safety guarantees are strictly scrutinized, the company determined that "simply prohibiting use would only induce 'Shadow AI' (hidden usage) that is beyond management's reach, and would not be a fundamental solution." Therefore, rather than a simple ban, they chose the path of balancing governance and convenience by providing Gemini—which guarantees high-level security for business use—as an official infrastructure. Aiming for a company-wide rollout of Gemini, they launched a project aimed at organizational utilization, not just distributing the tool, so that employees could use it safely and effectively in their daily work.

Reasons for Choosing Yoshidumi Information's Support In selecting a partner, Yoshidumi Information was highly evaluated for its deep knowledge of not only Gemini but the entire Google Cloud ecosystem, including BigQuery and Looker, and for its proposals that looked ahead to future data utilization. Furthermore, the content of "AI Driven Premium," which focuses on applying AI to actual work through workshops rather than just explaining operations, was the deciding factor, as it aligned with Japan Lifeline's goal of autonomous utilization in the field.

Results of Implementation Support Through training and Q&A sessions conducted via Yoshidumi Information's "AI Driven Premium," the psychological hurdles employees felt toward AI were lowered, and numerous concrete examples of operational improvement have been created.

- Significant increase in the number of Gemini users: Due to the training, the number of active users increased by approximately 30%. A culture was born where employees shifted from a passive attitude of "I have to learn this" to spontaneously sharing, "This is what I found useful about Gemini." - Cultivating culture through "Gemini News": The Information Systems Department produces and publishes a monthly short video content series called "Gemini News," which explains how to use AI in an easy-to-understand manner. They use Gemini itself to produce these videos, actively demonstrating the convenience of AI to the company. - Operational efficiency from the field: The marketing department utilized NotebookLM to build a system that can instantly extract necessary information from vast amounts of internal documents. Additionally, administrative staff have built Google Sites themselves while interacting with Gemini, and the IT department has automated communication log analysis by generating Google Apps Script code. Tasks that were previously "wanted to be done but couldn't due to lack of knowledge or time" are now being solved through field-led initiatives.

Comments from Japan Lifeline Co., Ltd. Representatives Moving forward, our goal is to spread the know-how of employees who are leading the way in utilization and further expand the base of users. Ultimately, we want to establish Gemini as "everyone's best assistant." As work diversifies, we want to leave what can be left to AI, and have humans spend more time on "thinking" and "creating." We will continue to pursue an organization where the true value of humans is demonstrated. For companies considering the introduction of Gemini, we recommend taking the first step without overthinking it. We are convinced that providing employees with the opportunity to welcome AI as an excellent partner is a powerful force that will open up the future of the organization.
