Can someone tell me the exact difference between them. All I can really seem to gleam is that Kogal girls or guys are trying to look tanned and Ganguro "gals" or guys are tied in with the Hip Hop culture in japan. Oh and they both use copious amounts of fake tan!

Any help would be great! :

This is what this web site is about find your answers to everything in Japan!

In short:
Kogal are a take off of the valley girl, and spend copius ampunts on their desiner goods and outfits. - although still pretty grungy looking

Ganguro (Dirty Girls) - Are the cheapear take off Kogarus, and are basically social outcasts, or rebellious teenagers.

Yamanba - Are extreme Ganguro kids, they wear even more outragous makeup and clothing.

Detail:
Kogal (?, kogyaru?) is a subculture of girls and young women in urban Japan, one of several types of so-called gals. They are characterized by conspicuously displaying their disposable income through distinctive tastes in fashion, music, and social activity. In general, the kogal "look" roughly approximates a sun-tanned California Valley girl

Kogals are known for wearing platform boots, a miniskirt, copious amounts of makeup, hair coloring (usually blonde or brown), artificial suntans, and designer accessories. If in school uniform, the look typically includes skirts pinned very high and loose socks (large baggy socks that go up to the knee). Kogals' busy social lives and desire for new material goods leads them to be among the first consumers of Japanese cell phone technology, and their taste in clothes tends toward names such as Burberry scarves and Louis Vuitton handbags. Kogals spend much of their free time (and their parents' income) shopping, and their culture centers on the Shibuya district of Tokyo, in particular the 109 building, although any major Japanese city is sure to have at least a small population. During the summer, kogals may sometimes be seen at the beach. They are generally not seen in high-end department stores.

Ganguro (?, Ganguro?) is an alternative fashion trend among young Japanese women, and some men which peaked in popularity around the year 2000, but remains in evidence today. The Shibuya and Ikebukuro districts of Tokyo are the center of ganguro fashion.

Yamanba (?, Yamanba?) is a newer term often used to describe extreme practicioners of ganguro fashion. Yamanba feature darker tans and add white lipstick, pastel eye makeup, tiny metallic or glittery adhesives below the eyes, brightly-colored contact lenses, plastic dayglo-colored clothing, and incongruous accessories to the ganguro look. Some yamanba wear stuffed animals as decorations. The male equivalent is called a "center guy" (??, Sentaagai?, Center Street), a pun on the name of a pedestrian shopping street near Shibuya Station in Tokyo where yamanba and center guys are often seen.

NOTE***I have been working on this subject for the Japan Guide but have not finished. If anyone has an interest in Japanese fashion and wants to write some articles on this subject let me know!
