My god, she's Japanese. If you don't like the choice fine, but don't go after her ethnicity and identity. Taking away her achievements by calling it "wokeness" is garbage. She's the most recognizable Japanese athlete in 2021. Sorry if she doesn't fit your outsider qualification of what that should look like, but that doesn't mean she's not worthy of recognition or of her heritage.
Should she go play tennis for Haiti? But then the same problem arises, she's only half Haitian (and not even born there). I guess she should just not exist in the sporting world, then. Otherwise it's just "Wokeness" and "diversity" instead of, you know, someone existing and being good at their sport.
