On the day, junior and senior high school students, teachers, researchers, and corporate representatives from across Japan,A total of 415 peopleNext-generation researchers engaged in cross-border research exchange, with their participation.

This tournament,12 oral presentations and 48 poster presentationswas held,14 partners including companies and universitiesparticipated. Also, in the poster presentations, graduate students, doctoral degree holders, and researchers in the workforce, etc.12 research coachesParticipants engaged in in-depth discussions with each presenter.

Science Castle: A Growing Research Community

At Science Castle, we emphasize "inquiry," "action," "integrity towards data," "passion," and "vision" as important common elements for researchers. The presenters shared not only their research findings but also the reasons for undertaking their research and their hopes for the future, leading to lively discussions.

At the poster session venue, many scenes unfolded where presenters and attendees engaged in dialogue while facing each other, with questions sparking new perspectives and ideas. It was a day where research connected even those meeting for the first time, leading to encounters with new colleagues, truly expanding the research community.
