The release of This is Karate can be credited as a major factor in the global spread of Kyokushin Karate. Its Japanese counterpart, Secret Kyokushin Karate, offers an entirely different set of techniques and training methods that differ greatly from modern-day Kyokushin Karate.
In fact, it would not be an exaggeration to say that these techniques were heavily influenced by various martial arts styles and systems that Master Masutatsu Oyama had studied and practiced throughout his life. These included karate, jujutsu, stick fighting, judo, and even elements of boxing, which Shihan Masutatsu Oyama incorporated during his youth. While many now associate Kyokushin with its signature full-contact matches without face attacks, this was originally just one way to popularize the art form.
The true essence of Kyokushin lies in its culmination of diverse martial arts principles under the guidance of Master Masutatsu Oyama.
