Harajuku Style varies considerably and there are many different looks ranging from elegant gothic lolita to punky modern looking Visual Kei - which is inspired by japanese rock group (jrock).
Too see the japanese teen culture at its most intense, go to Harajuku on a Sunday, when many teens congregate around Harajuku Station and take part in costume play (cosplay), dressed up in outlandish costumes to appear like anime characters, punk rock musicians, and various harajuku gothic styles.
Tokyo is a huge fashion epicentere around the world. Youths in Japan dress in vibrant clothing. They mix and match different clothing styles and create their own style, sometimes with big coloured hair and cute accsessories. While many people from all around the world are influenced by Harajuku, the real Harajuku style fashion stays where it originated from - in the area itself.
