Kobudō or koryū are the opposite of these terms referring to ancient martial arts established before the Meiji Restoration.

This definition is incorrect as sumo is an ancient art that has attained popularity and media coverage in the modern era.

For example, Kano Jigoro (嘉納 治五郎 Kanō Jigorō, 1860–1938) founded judo in part as an attempt to systematize the myriad traditions of ju-jitsu which existed at the time.

Whereas in most gendai budō dojo all are welcome provided they follow basic rules of conduct, koryū instructors often strictly scrutinize candidates.

The primary purpose of gendai budō is for spiritual and mental development through the study and application of East Asian metaphysical techniques and teachings.
