Well I don't see why the heck not! How many times do you see a Japanese person in traditional African dress? Or how many times do you see woman in wedding gowns from paris and dresses made by famous fasion people?
I don't know if you've been to Little Osaka, Little Tokyo, or Japan Town in America I don't know any more Japan towns besides those but they have Japan festivals called ''Obon Festivals'' or ''Bon Festivals'' at these festivals you see a high amount of japanese people(those towns are where they premerly live here in america) and the rest are usually African American or Caucasian they have people their known as Taiko Drummers wearing Japanese Happi Coats while they drum I've also seen people wearing Yukatas there here are a few videos.

Some races need to stop this friggin this getting angry over little things.I've seen a butt load of Japanese people wearing African Clothes, Stuff from Paris, Cloths from Italy, baking European Pastries like the famous ''Straw Berry Short Cake'' that they try to play off as being Japanese. American and Canadian made Business Man Suits. American blue jeans. Nikes and Jordans. I haven't seen one normal Japanese person wear normal japanese origin cloths and i don't mean ''Jeans made in japan'' I actual new species of cloths made in japan.
Please don't stress and wear you yukata to a festival u look silly wearing those in normal day enjoy your self.
Cheers, Kevin Mix of Japanese, African American, and more
