There's some novels like "From the New World" which are excellent novels and award winner, but never make it over here. They still fall into the "otaku" subculture but appeal to broader audiences, too.
As consumers, has some sort of crowd-funding or the like ever been attempted to get these materials translated? How can consumers express their desire to bring this material overseas?
The best way to do convince distributors this works reliably is to make sure that it does by backing similar projects whenever you see them. As noted above there are a number of projects that have been successful like LWA2 and kick-heart. If someone like Trigger keeps running kickstarters and making upwards of half a million dollars, well, the rest of them will catch on.
