We are thrilled to extend a warm invitation to the 15th International Conference on Education, Research, and Innovation (ICERI 2025), which will be held in the vibrant city of Osaka, Japan, from July 29 to August 1, 2025. Hosted by Kansai University, ICERI 2025 will serve as a workshop conference under the umbrella of the 9th International Conference on Education and Multimedia Technology (ICEMT 2025). Building on the success of previous ICERI events held in dynamic locations such as Cairo, Egypt; Phnom Penh, Cambodia; Bandar Seri Begawan, Malaysia; Bangkok, Thailand; Rio de Janeiro, Brazil; Beijing, China; Taipei, Taiwan; and Tokyo, Japan, we are excited to return to Osaka. Known for its rich cultural heritage and technological innovation, Osaka is the perfect setting for ICERI 2025, where we will continue to explore the frontiers of Education, Research, and Innovation. We look forward to your active participation in ICERI 2025, an exciting opportunity to exchange ideas, foster connections, and advance the collective knowledge in these fields. Together with Kansai University, we will ensure that ICERI 2025 becomes a memorable and enriching experience for all attendees.
