Jan. 9, 2026 We visited the Hokkaido Nippon-Ham Fighters Kamagaya Stadium.
We visited the Hokkaido Nippon-Ham Fighters Kamagaya Stadium and took a tour of the facilities. Additionally, we introduced the overview of our motion analysis support to the team’s analysts and sports scientists and discussed more effective ways to utilize data, approaches to feedback, and organizational structures. It was a meaningful and valuable opportunity to learn how team staff members who work with professional athletes provide scientific support.
