Ko-ryū
is a Japanese term for any kind of Japanese school of traditional arts. The term literally translates as "old school" or "traditional school". It is sometimes also translated as "old style".
Ko-ryū is often used as a synonymous shorthand for, ancient Japanese martial arts that predate the Meiji Restoration of 1868. In English, the International Hoplology Society draws a distinction between Koryū and Kobudō martial arts based on their origin and the differences between their ranking of priorities concerning combat, morals, discipline, and/or aesthetic form.
''Ikebana'' (flower-arranging)
Ko-ryū is one of the oldest and most traditional schools of Ikebana. From it, various other schools have formed that carry its name, such as the Nihon Ko-ryū, Katsura Ko-ryū, Miyako Ko-ryū, Ko-ryū Shōshōkai, Ko-ryū Toyokai,.
