Ryū 流
Japanese suffix meaning style or school, used in the names of martial arts, ikebana and calligraphy schools and also in kinbaku school names such as Osada-ryū and Yukimura-ryū.
Ryū is the Japanese term for a school in any discipline, used in the sense of ryūha. The character carries meanings such as style, manner, system and school, and it is mostly used as a suffix. English speakers meet it most often in the names of martial arts schools, but it also marks schools of ikebana and calligraphy.
Kinbaku schools use the same pattern. Osada Steve’s own timeline says he established Osada-ryū and opened its head dojo in Tokyo in June 2007. Karada House writes that Yukimura Haruki began formal teaching of Yukimura-ryū in 2006, and that Murasaki Haruan was certified as one of its instructors in 2014.
