If you walk out of the Harajuku train station on a Sunday afternoon, turn left and walk about a block down the street.  Just past the entrance to the subway there is a bridge that crosses over the train tracks and leads to Yoyogi Park and the entrance to the Meiji Shrine.

The bridge is a popular hangout spot for kids - you'll see bands playing, kids impersonating their favorite bands, some Lolitas (girls dressed up in elaborate and very detailed outfits made to resemble Victorian dolls) and a lot of other kids dressed up in costumes to resemble anime or fantasy characters, called 'cosplay'.

(read about it here: http://en.wikipedia.org/wiki/Cosplay )

I was really impressed and amazed at some of the costumes, and the whole phenomenon in general.  Here's what I saw on the bridge

(I'm leaving for Asia again tomorrow - a couple of weeks in Hong Kong followed by a week or so in Australia.  See you guys in about a month...)
