稽古(けいこ) means practice or training, especially in martial arts, performing arts, and other traditional disciplines.

稽 means to consider or examine, and 古 means old. Together they point to learning by studying what earlier practitioners passed down.

Compared with the general word 練習(れんしゅう), 稽古(けいこ) is closely associated with training under an established tradition or teacher.

You will hear 稽古 for kendo, judo, karate, kabuki, noh, and tea ceremony. It can refer to a training session as well as the practice itself.
