I found a website from Japan that has a lot of pictures of tournaments in Japan. These pictures are taken within the last ten years.
Tourneys of four ball, both men and womens, and sometimes women playing with men are shown. I know that the starting position in four ball in Japan is different then in Korea, but in the pictures it looks like people who have the white are caroming into one of the reds and the yellow ball instead of caroming into the two reds only and avoiding the other cue ball, confusing
Several cadre tourneys of 47/2 on the match tables and 42/2 on what I guess are nine foot tables. There are pictures of Koboyashi and his son playing against each other in a 47/2 tournament. I am not sure but I think there is ladies three cushion tournament photos also.
