Fall fashion trends

I’ve noticed an unusual trend in fall fashion–there’s a lot of Japanese influence in clothing.
I don’t mean kimono are popular. It’s more of a fusion. T-shirts have things written on them in Japanese and sumi-e style drawings. Parachute pants and tunic tops have patches of chirimen (a textured silk with vivid floral patterns) sewn onto them.
This is strange. Once every few years an American or European designer will use Japanese influences in his haute couture line, but I’ve never seen locally produced, casual clothing with such a strong and obvious Japanese twist.
I like it. But I wonder if the slogans on those Japanese t-shirts are as weird as the English ones are?
