There's a chance that they even had Japanese actresses try out for the part, but who knows. From a business perspective (whether or not you like the lead role choice), this made the most sense for a global, mainstream movie. She's recognizable through the world from Marvel and other movies. In many many cases, the celebrities' names are enough to sell a movie and tickets. The movie industry is a business, and it's up to the team if it's about making a movie or if it's about creating their art at a possible loss. It all depends on who is making it.
I would've liked a Japanese person for the role, but realistically that just wouldn't happen, with no huge Japanese names in Hollywood/tv/etc., right now. I feel like the movie did try to compromise, but people are taking it the wrong way, and finding ot offensive, rather than something they tried to do, more for the fans, possibly.
If anything, I am honestly surprised that I don't remember any controversy around Live Die Reprat/Edge of Tomorrow, where Tom Cruise (a huge, globally-recognized) name, played the role of a Japanese teen. I enjoyed both the original book/manga, and the movie, myself. In the end, you really can't make everyone happy, why simultaneously trying to make money.
