Let's enjoy the heated "Debate Forum" (Gekiron Colosseo) at Makuhari Messe: A report of the 45th Annual Meeting of the Molecular Biology Society of Japan (MBSJ2022).

The 45th Annual Meeting of the Molecular Biology Society of Japan (MBSJ2022) was held at Makuhari Messe in Chiba Prefecture from November 30 to December 2, 2022. We decided to make MBSJ2022 as the place for heated discussion and organized the meeting with the theme for MBSJ2022, heated "Debate Forum" (Gekiron Colosseo in Japanese). We had more than 6000 participants, and we believe that the meeting was finally ended in great success, as approximately 80% of survey respondents were generally satisfied with MBSJ2022 (https://www.mbsj.jp/meetings/annual/2022/enq.html). To implement the heated "Debate Forum," we carried out many new projects; introduction of graphic abstracts, "Science Pitch," "Meet My Hero/Heroine," MBSJ-ASCB-EMBO joint sessions, a solo exhibition of Grant-in-Aid applications, a theme song, live classical music, elaborate photo booths, and a compact guide map, all together enabled close interaction among the participants. For the implementation of these unprecedented projects, here, I would like to summarize how we organized this meeting and our intentions.
