I know a Filipino girl who likes Pikachu a lot and she's 23; she's an artist though.
I also know lots of girls like Hello Kitty, not just Asians. Hello Kitty is an international brand though.
I'm a 23 year old grad student in England and over 60% of my classmates are Chinese and the girls LOVE Doraemon. They don't even read manga/ very few watch anime but they love Doraemon/have plushies,etc. We don't even get Doraemon in the UK so I had to google 'Blue cat anime' or 'Japanese blue cat manga'
They don't even watch Dragonball/Naruto/One Piece and some have no clue about Tenchi Muyo (I have seen all of the Tenchi series revolving around Tenchi but only liked Universe and the Kagato saga of Muyo).
So why is Doraemon, a JAPANESE cartoon, so popular in China (last I checked most Chinese though they don't hate Japanese, they don't like them either)??
