Haven't seen a thread on this before, but some people who are more causal fans of Pokémon might not know this, so I decided to make a thread on it to clear up some common misconceptions. As Jynx isn't the most popular Pokémon... yeah.
Don't kill meh, Admins :c

Anyway, what do you see at first glance?

A lot of you are going to see a racial stereotype, but a small few of you will see Ganguro. What is ganguro? Well, this:

Ganguro is a Japanese fashion for females, which consists of tanning your skin dark brown, and dying your hair blond, silver or orange, or a similar colour. Most Ganguro girls also wear brightly coloured outfits. The word "Ganguro" actually does mean "black face", but isn't meant in a racist way, it simply refers too the girls darkly tanned face.

Believe it or not, this odd fashion was really popular, and still it. Look at Jynx, and look at the Ganguro girl. Dark face? Blond hair? Bright red dress?

Ganguro started too appear in the early 1990's, and became really popular (for some reason) around the year 2000. Apparently the Shibuya and Ikebukuro districts in Tokyo are a hot-spot for groups of ganguro girls, but I can't confirm this as I've never been to Japan.

Now, I'm not saying Jynx is defiantly based on a Ganguro fashion girl, but look at Nintendo. Kid friendly. I doubt they'd ever allow something even slightly racist too grace their games. And when you think about it, Ganguro is a Japanese fashion, and Pokémon is Japanese, making it highly likely Jynx's origins are not meant too be racist, but meant to be a harmless reference to the fashion of Ganguro.

Wikipedia Article on Ganguro, for further reading. >>

More Ganguro girls.

I know this is mentioned on Jynx's Bulbapedia page, but I doubt many people actually visit Jynx's page. So yeah. And I know probably a lot of people think Jynx wasn't meant to be a racial stereotype, but not a lot of people really know that she was based off Ganguro.

I hope you guys liked the information here. I don't claim too be an expert when it comes to Ganguro so yeah xD

EDIT

The above image was found on Photobucket, I don't know what episode it was from.

Ganguro has appeared in Pokémon in a form other than Jynx... the form of Jessie and James dressing up.
