The 45th Belle II Japan Workshop was held at the High Energy Accelerator Research Organization (KEK) on March 12th-13th, 2026. About 20 students from various universities participating in the Belle II experiment, ranging from undergraduate to PhD students, attended the workshop. At this workshop, students presented their thesis research, including presentations by two undergraduate students from our laboratory. In the Q&A sessions, lively discussions developed across different universities and research fields. This provided an excellent opportunity for students to network and deepen their understanding of each other's research. The presentation slides in Japanese are as follows.
