[Objective] To examine trends in the interests of Japanese abstract applicants for IPMHE 2025 (Indo-Pacific Military Health Exchange) jointly hosted by the United States and Japan in December 2025. [Methods] We analyzed the title, country of registration, and field of application (10 fields in total) of abstracts accepted for IPMHE 2025. The field of application for accepted abstracts was analyzed based on the applicants' first preference. [Results]: A total of 287 abstracts were accepted from 17 countries. Of these, 116 (40.4%) were from the host country, the United States, and 82 (28.6%) were from Japan. By Education and Training/ Multilateral collaboration was the most common overall, accounting for 53 cases (18.5%), followed by Military medical research (44, 15.3%) and Operational medical care/ Tactical medicine (43, 15.0%). On the other hand, among submissions from Japan, the order of topics was Military medical research (17 presentations, 20.7%), Other (15 presentations, 18.3%), and Education and Training/ Multilateral collaboration (12 presentations, 14.6%). Comparing Japanese and international submissions, the highest proportion of Japanese submissions was Other (15 vs. 4), Force health management/ Public health (11 vs. 14), and Military medical research (17 vs. 25). Within the "other" category, the majority of Japanese submissions were research (6 presentations) and case reports (6 presentations). [Discussion] The fact that presentations and Q&A sessions were in English may have influenced the trend in presentation submissions. However, it can be inferred that interest in Force health management/ Public health and Military medical research is not low in Japan. It is expected that Japan will continue to increase its ability to communicate the research results to the world in these categories. [Conclusion] Among general submissions for IPMHE2025 from Japan, the proportion of presentations related to Force health management/ Public health and Military medical research was higher than that from overseas.
