大東流合気柔術
Although Japanese aikido and Korean hapkido share common technical origins, in time they have become separate and distinct from one another. They differ significantly in philosophy, range of responses, and manner of executing techniques. The fact that they share the same Japanese technical ancestry represented by their respective founders practice of Daitō-ryū Aiki-jūjutsu, and that they share the same Chinese characters, despite being pronounced "ai" in Japanese and "hap" in Korean, has proved problematic in promoting Hapkido internationally as a discipline with its own set of unique characteristics differing from those common to Japanese martial arts.
