Only sites that are related to koryu will be admitted. Inappropriate sites are subject to rejection.Koryu means "old flow". This refers to the fact that these traditional Japanese martial arts have "flowed" from teacher to student over several centuries. These martial arts are vastly different in character from teh gendai bugei or modern martial arts such as judo, karate, aikido, etc.
For this directory, Daito-ryu aikijujitsu is not listed as a koryu but has its own category at http://dmoz.org/Sports/Martial_Arts/Aikido/Aiki_Jutsu_and_Aiki_Jujutsu/Daito_Ryu/
