There are more than 350 F3A pilots in Japan, I don't think they can produce that much more to cover Japan and the rest of the world, maybe is just that, they can't make enough airplanes. The 350 I got from the pilots standings from sakura f3a, I can be mistaken anyway.
Think about this. If you use the same technique and add up FAI scores posted in the NSRCA District Championship points race each year you get somewhere around 90 F3A pilots in the USA!!!
The US has nearly 2.5 times the population of Japan and only about 25% of the number of F3A pilots!!
Fun with numbers late at night!!
