We held the 2023 Hongo Summer Dojo on August 5, 2023. The program’s theme was “Diversity, Inclusion, Uniqueness, and Universality, Toward Global Collaborative Nursing Research.” The program aimed to enhance university matching and collaborate nationally and internationally. The program was held hybrid, and a total of 77 faculty members and graduate students, from 11 universities, as well as UTokyo Nursing, participated. The program consisted of research presentations by nursing faculty members and valuable discussions on them. After the program, a social gathering was held, which was a great opportunity to share and exchange information. With the success of this program, UTokyo Nursing has demonstrated its commitment to promoting international collaboration and advancing the field of nursing science. We would like to thank everyone who participated in the 2023 Hongo Summer Dojo at UTokyo.
