Yoshidumi Information Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Harumichi Akita; hereinafter 'Yoshidumi'), a Premier Partner (Co-sell & Services) for Google Workspace, announces its support for the implementation of Google Workspace and generative AI 'Gemini' for approximately 5,000 employees at the Tokushima Prefectural Government (location: 1-1-1, Bandai-cho, Tokushima City, Tokushima Prefecture; Governor: Masazumi Gotoda).
■ Overview of Implementation
Tokushima Prefecture has been actively promoting internal DX (Digital Transformation) to enhance citizen services and enable diverse work styles. As part of this initiative, Google Workspace was selected through a bidding process and has now been launched as a new communication platform for approximately 5,000 employees.
■ Key Usage and Adoption Results
Utilization of Generative AI 'Gemini':
Thanks to its ease of use and high response accuracy without requiring specialized skills, Gemini has rapidly gained traction among staff, achieving an active user rate of 75%. Its application spans various aspects of daily work, delivering tangible productivity improvements beyond traditional use cases such as meeting minutes creation.
Spontaneous Application Development by Staff:
Employees are actively leveraging tools like Google Apps Script, Gemini, and Gem to develop custom applications for improving work efficiency.
Establishment of an Application Sharing Catalog:
An 'Application Sharing Catalog' has been created on the internal portal site, allowing employees to register and access self-developed tools. This includes diverse utilities such as PDF merging/editing apps and EML file import tools for Gmail, all contributing to streamlining daily operations.
■ Support Provided by Yoshidumi Information
To reduce psychological barriers during the transition to the new environment, Yoshidumi Information conducted a total of four training sessions for employees.
■ Comments from Tokushima Prefectural Government Representatives
'Going forward, it will be essential for each employee to fully understand the innovative design principles and strengths of Google Workspace—such as real-time collaboration, online completion, and paperless workflows—and to reconsider their work processes accordingly. True DX will only advance if we go beyond simply replacing tools and actively transform our work styles to align with the ecosystem of Google Workspace.'
