The pictures on their website are even worse than you might expect from the excerpts here. Like, virtually every other picture is kimono + yellowface + some weird Western fantasy of Japan. Apparently this is how their "progressive interpretation and view of Japan" translates, because the way one progressively updates kimonos is with nipples and pubic hair.
I don't remember particularly offensive Japanese stereotyping of "Americans." For sure Japan has serious issues with how they treat and think of foreigners, especially blacks, Chinese, and Koreans, but offensively stereotyping white Westerners isn't particularly prevalent. At least not so far as visual depictions go (many do think that Westerners are much more likely to riot, loot, and commit crimes, especially in the aftermath of a major earthquake).
