On May 27th and 28th, 2023, the 2023 Annual Meeting of the Japan Institute of Fire Science and Technology was held at Hirosaki University in Aomori Prefecture. From our laboratory, two master's students (M2) and Imamura presented their daily research results. The Fire Science Society was held face-to-face for the first time in three years, and there were a large number of participants, and we were able to actively exchange opinions. Face-to-face academic conferences are stimulating. We will continue to actively present at academic conferences in order to advance cutting-edge research. However, it was a pity that I couldn't fully enjoy the city of Hirosaki because I couldn't stay long enough (Suwa ⇔ Hirosaki took 7 and a half hours).
