Maybe I am wrong, but I have always perceived that the influence of Japanese culture on America is no longer as strong as it was in the 90s and early 00s. That could be my childhood bias though.
Japanese pop culture (specifically, anime and video games) seems to have become more mainstream in the US across various demographics, likely due to the web and streaming services like Crunchyroll and obviously video games, but also because the generation that held it as a cultural niche has grown up and become the standard bearers for current American culture.
Mainstream pop and rap artists are making anime references in their music now, and plenty of modern animation and movies making nods to it, even adopting the anime aesthetic (like Avatar, Teen Titans and RWBY.)
