On December 20, 1959, a Muay Thai among Thai fighters was held at Tokyo Asakusa town hall in Japan. Tatsuo Yamada, who established "Nihon Kempo Karate-do", was interested in Muay Thai because he wanted to perform Karate matches with full-contact rules since practitioners are not allowed to hit each other directly in karate matches. At this time, it was unimaginable to hit each other in karate matches in Japan. He had already announced his plan which was named "The draft principles of project of establishment of a new sport and its industrialization" in November, 1959, and he proposed the tentative name of "Karate-boxing" for this new sport. It is still unknown whether Thai fighters were invited by Yamada, but it is clear that Yamada was the only karateka who was really interested in Muay Thai. Yamada invited a Thai fighter who was the champion of Muay Thai (and formerly his son Kan Yamada's sparring partner), and started studying Muay Thai. At this time, the Thai fighter was taken by Osamu Noguchi who was a promoter of boxing and was also interested in Muay Thai. The Thai fighter's photo was on the magazine "The Primer of Nihon Kempo Karate-do, the first number" which was published by Yamada.
There were "Karate vs. Muay Thai fights" February 12, 1963. The three karate fighters from Oyama dojo (Kyokushin later) went to the Lumpinee Boxing Stadium in Thailand, and fought against 3 Muay Thai fighters. The 3 Kyokushin Karate fighters' names are Tadashi Nakamura, Kenji Kurosaki and Akio Fujihira (as known as Noboru Osawa). Japan won by 2-1: Tadashi Nakamura and Akio Fujihira both KOed opponents by punch while Kenji Kurosaki was KOed by elbow. This should be noted that the only Japanese loser Kenji Kurosaki was then a Kyokushin instructor rather than a contender and temporarily designated as a substitute for the absent chosen fighter. Noguchi studied Muay thai and developed a combined martial art which Noguchi named kick boxing, which absorbed and adopted more rules than techniques from Muay Thai. The main techniques of kickboxing is still derived from Full-Contact Karate (Kyokushin). However, throwing and butting were allowed in the beginning to distinguish it from Muay Thai style. This was later repealed. The Kickboxing Association, the first kickboxing sanctioning body, was founded by Osamu Noguchi in 1966 soon after that. Then the first kickboxing event was held in Osaka, April 11, 1966.
Tatsu Yamada died in 1967, but his dojo changed its name to Suginami Gym, and kept sending kickboxers off to support kickboxing.
Kickboxing boomed and became popular in Japan as it began to be broadcast on TV. By 1970, kickboxing was telecast in Japan on three different channels three times weekly. The fight cards regularly included bouts between Japanese (kickboxers) and Thai (muay thai) boxers. Tadashi Sawamura was an especially popular early kickboxer. In 1971 the All Japan Kickboxing Association (AJKA) was established and it registered approximately 700 kickboxers. The first AJKA Commissioner was Shintaro Ishihara, the long time Governor of Tokyo. Champions were in each weight division from fly to middle. Long time kickboxer Noboru Osawa won the AJKA bantam weight title, which he held for years. Raymond Edler, an American university student studying at Sophia University in Tokyo, took up kickboxing and won the AJKC middleweight title in 1972; he was the first non-Thai to be officially ranked in the sport of Thai Boxing, when in 1972 Rajadamnern ranked him no. 3 in the Middleweight division. Edler defended the All Japan title several times and abandoned it. Other popular champions were Toshio Fujiwara and Mitsuo Shima. Most notably, Fujiwara was the first non-Thai to win an official Thai Boxing title, when he defeated his Thai opponent in 1978 at Rajadamnern Stadium winning the Lightweight Championship bout.
By 1980 due to poor ratings and then infrequent television coverage the golden-age of kickboxing in Japan was suddenly finished. Kickboxing had not been seen on TV until K-1 was founded in 1993. In 1993, as Kazuyoshi Ishii (founder of Seidokaikan karate) produced K-1 under special kickboxing rules (No elbow and neck wrestling) in 1993, kickboxing became famous again.
