This interview with Yoon Dae-hyun Sensei, the founder and president of the Korea Aikido Federation, was conducted during the organization's 30th anniversary celebration. Mihaly Dobroka and I were invited, along with Igarashi Kazuo Shihan, Takimoto Seizo Shihan, to give a class and a demonstration during that milestone weekend. I took the opportunity to ask Yoon Sensei to walk us through his martial arts background, and addresses controversial aspects of Korean and Japanese martial arts history, including the confused relationship between Korean Hapkido and Japanese Aikido, mythical figures like Shinra Saburo, and historical connections between key figures like Choi Yongseol and Ueshiba Morihei, while exploring the challenges of introducing Japanese martial arts in Korea and how Aikido's philosophy of peace and harmony offers solutions to modern social challenges.
