Chihiro “Senco” Ono started Ultimate in 2001 at the University of Tokyo. Since her early stage she has been into Ultimate rules and loved to discuss on and off the field. In 2006 she met a diverse pick up community called “Tokyo Ultimate”, which gradually formed itself into IKU, a mixed club team. IKU played WUCC 2010 in Prague. Senco also played WMUCC 2018 in Winnipeg, where she captained a master mixed team Wasabi and won Spirit Award. It was one of the most memorable tournaments for her and she started sharing the knowledge and experience in the Japan Ultimate community. Around the same time she founded the JFDA SOTG Committee and joined WFDF SOTG Committee as well. She was also a Game Advisor and served at WU24 2019 in Heidelberg.
