The Okinawan martial art "ti" was practiced by Okinawa royalty and their retainers for centuries before, and alongside, later Chinese influences. For the most part there were no particular styles of "ti", but rather a network of practitioners with their own individual methods and eclectic traditions. Early styles of karate are often generalized as Shuri-te, Naha-Te and Tomari-te, named after the three cities in which they emerged, although these are not concrete distinctions. Each area (and the teachers who lived there) had particular kata, techniques, and principles that distinguished their local version of "ti" from the others.

Kyokushin is a style of stand-up, full contact karate founded by Choi Yeong-Eui aka Masutatsu Oyama (최영의;大山倍達) in 1964. Kyokushinkai is Japanese for "the society for the ultimate truth." A very practical method of self defense, Kyokushin is deep rooted in the philosophies of self-improvement and discipline. Its full contact style has had international appeal (practitioners number between 10 million and 20 million).

Kyokushin has influenced much of the "full-contact" school of karate, emphasizing realistic training, physical toughness, and practicality in its training curriculum. Many other martial arts organizations have "spun-off" of Kyokushin over the years, with some adding additional techniques, such as grappling, but usually continuing with the same philosophy of realistic and practical training methods.
