Racially, Japan is much less diverse than America, so we might expect to see many more Japanese designers relative to a documentary focused on other places. (We might still see more local prejudices, though, if—for example—people from a certain region of Japan were excluded).
Let's stay focused on the trailer, though: people of color are completely absent, which is not representative of the design community, even in Silicon Valley. And if we pull back to the design community, people of color are still underrepresented compared to the general population.
