This year's theme: "MyData in Practice"

In 2024, we discussed how to incorporate the principles of MyData into the design of systems, technologies, and businesses, with the theme of "MyData by Design." As the next step, in 2025, we will focus on how to make the design work in the real world, and explore the possibilities and challenges of implementing MyData through examples from around Japan. (I will also be speaking for about 15 minutes at the beginning of the forum.)

This year's features

In addition to the traditional case presentations, we will emphasize mutual interaction between participants and invite general participants to the social gathering. We hope that this event will be utilized as a forum for dialogue that transcends the diverse positions of companies, government agencies, research institutes, non-profit organizations, educational institutions, and civil society.

Main Themes and Objectives

The central theme of this conference is "MyData in Practice," focusing on "how to make the concept of MyData work in the real world." While "MyData by Design" in 2024 discussed "the design necessary to realize MyData" from the multifaceted perspectives of BLTS (business, law, technology, and society), 2025 will "take that discussion one step further and focus on practical efforts regarding concrete implementation and operation," placing emphasis on more practical aspects.

The specific objectives include the following:

  • We will delve deeper into the possibilities and challenges of "MyData implementation" through ongoing examples in Japan.
  • We will present examples of MyData-related projects both in Japan and overseas.
  • "The social gathering will be open to the general public as an opportunity to promote mutual interaction among participants," and will provide a "space for dialogue that transcends diverse expertise and positions and expands the possibilities for future collaboration and co-creation."
  • In order to "establish the new trend of individual-centered data utilization in the real world," the initiative encourages the participation of a diverse range of stakeholders, including companies, government agencies, non-profit organizations, research institutions, educational institutions, and civil society.

I had the opportunity to speak at MyData Japan 2025.
I feel a little intimidated, wondering if it's really appropriate for me to be here among such renowned experts, but I hope to be able to offer some insight that only a newcomer can offer.
The event will be held on Thursday, July 7th @ Hitotsubashi Auditorium.
