I honestly have never heard the word Kawaii, until recently. I just thought maybe they accidentally mixed the H with a K. Anyway, Kawaii means "Cute" in Japanese and has become this whole type of culture, I guess just like Harajuku. I could be wrong, but that’s the impression I get. Anyways, I came across these really cute webcomics by Kawaii Not and OMG some are so funny I literally LOL’d at my desk at work!
Here are my favorites. I love the sense of humor! I totally get it. 
I’m officially obsessed with anything "Kawaii!" 
I love these comics! She has a book at Urban Outfitters too!
