These Kata were created ay the request of Gen Hayakawa (governor of the Okinawa Prefecture) via the Karate-Do Special Committee.
The idea was to create standardised kata that would cut across all the various streams of karate, that were suitable for novices, and would provide a common grounding in the basics of karate.
The Pinans had been in existence for some time, but they were considered to be a summation of “Shuri-te” line alone (quite rightly) and hence were lacking the “Naha-te” side of things.
Shoshin Nagamine made the first kata (Fukyugata Ich) and Chojun Miyagi made the second kata (Fukyugata Ni).
Matsubayashi-ryu still practise them both.
Fukyugata Ni remains part of Goju-Ryu but under the revised name of Gekisai Dai Ichi (normally the first kata taught in Goju-Ryu).
Chojun Miyagi later went on to teach a second version of the same kata, which is largely the same, but with the addition of the circular hand motions common to other Goju kata.
This revised version of Fukyugata Ni / Gekisai Dai Ichi is called Gekisai Dai Ni (normally the second kata taught in Goju).
-Iain Abernethy says this... and it also stated in
Nagamine's (1976).
The Essence of Okinawan Karate.
Futhermore...
The kata were finished and introduced in 1941 in order to promote a basic and standard kata across a majority of Okinawan Karate styles, however only some styles continue to practice both, or one of these kata.
A third Fukyugata (Sandan) was composed by Sensei Ansei Ueshiro in 1960, consisting of 17 movements.
The Shorin-Ryu Okinawan Karate Question and Answer Book, written by William Cummins and Robert Scaglione, describes this kata as "characterized by techniques emphasizing speed, combinations and strong, low stances." However, this kata was never adopted in Okinawa Prefecture.
And to further add comlexity:
A third Fukyugata has been created (c. 2015) to showcase Uechi-ryu technique.
As for Mas Oyama developing any of these kata.... that is a nonsensical notion. He didn't start karate until 1946. He didn't create Kyokushin until a decade later.
In 1940, the Governor of Okinawa, Gen Hayakawa, assembled a prestigious Karate-Do Special Committee to address the need for easier basic kata for children.
It is important to note that the formation of the special committee was instigated by the government.
Previous karate groups and societies had been privately organized.
Except for the chairman, the members of the committee represented the new, or transitional, generation of karate instructors.
The list of the nine members was given to Charles C. Goodin by Nagamine Sensei [during an interview about this kata], this lists order: (1) Ishihara Shochoku (chairman), (2) Miyagi Chojun, (3) Kamiya Jinsei, (4) Shinzato Jinan, (5) Miyasato Koji, (6) Tokuda Anbun, (7) Kinjo Kensei, (8) Kyan Shinei, and (9) Nagamine Shoshin
