Ko-ryū (Japanese: 古流, "old school") is a Japanese term for any kind of Japanese school of traditional arts. The term literally translates as "old school" (ko—old, ryū—school) or "traditional school". It is sometimes also translated as "old style".

It is often used as a synonymous shorthand for Ko-budō (古武道), ancient Japanese martial arts that predate the Meiji Restoration of 1868.[1][2][3] In English, the International Hoplology Society makes a distinction for martial arts between Koryū and Kobudō concerned the origin and the difference between the ranking of priorities concerning combat, morals, discipline and/or aesthetic form.[4]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, and Ko-ryū Shōōkai (古流松應会).[5][6][7][8][9][10]
