Don’t let people make fun of you for liking japanese culture.
I am living in japan right now and let me tell ya:
There are people here who can’t speak or understand English who play nothing but Missy elliot and ludacris, even in businesses like housing offices and restaurants.
There are people who have cowboy hats and dead cow skulls in their home because they idolize what they assume American homes are like.
There are people who learn English strictly through music videos and American television shows.
There are entire karaoke bars with english songs often sung by people who have no idea what the lyrics mean.
Japan often takes American shows like the powerpuff girls and make japanese versions of them.
They often mistake common Americans for celebrities. I have been mistaken for Micheal jordan, tiger woods, Shaquille o'neal, Tyler perry, and saddest of all: queen latifa.
The act of sprinkling English into your japanese sentences is considered cute and cool and is popular with teenagers. Bonus points if you happen to use it correctly.
Japanese stores sell shirts with english on them and people buy them not knowing that most of those word combinations are nonsense.
Don’t let someone shame you for singing an anime opening, using japanese in your sentences, wearing clothing with japanese on it, ect. If anything, this is just one more thing that you have in common with them.
