The japanese are aking locations all over asia and the pacific, if not simultaneously, then near simultaneously. The stereotype of them before the second world war was that they were a kind of a copycat people who weren't capable of coming up with their own advanced designs themselves. People like the americans and the british will be shocked when they run into these fighter planes in the earliest part of this conflict on the American side. And it will be just the first of many to get an idea of how the racism allows the japanese to be underestimated.
