1945-1951. Approximately five years when judo disappeared from schools, professional judo emerged, and then Brazil. The name "Kimura" doesn't appear in the newspapers the day after the matches.
This traces the history of post-war judo and the 1951 Brazilian match, using contemporary newspapers and records.

▼ Counting method and notes
*UFC numbers are recounted using publicly available data compiled from UFC's official records (UFC Stats) (March 1994 - September 2026, 8,897 matches, 1,725 wins by submission). The names of the winning techniques were counted by compiling the way they were recorded.
For the 1951 Brazilian newspaper, I read the text from the pages made public by the National Library. Only numbers that were clearly legible were used. The Portuguese original text on the screen is included without alteration, only for parts where the characters could be verified from the image of the paper.
Where there were discrepancies in the sources (number of spectators, time of the match, whether the arm was broken, who named it), I did not choose one and listed them all together.
The theory that "sports journalists started calling it around 1959" is the theory written in the self-published book (Roberto Pedreira, 'Choque' Vol. 2).
