Traditionally, Harajuku on a Saturday morning attracts crowds of crazily-dressed kids with improbable hairstyles. This guy was reasonably normal, if anything; his friends were wearing various combinations of spiked collars, maid outfits, and insane robot costumes. (I’m kicking myself for not taking a photo of the robot dude.)
It’s people like this who give Harajuku its reputation as a goldmine of youth fashion trends. I dunno. I don’t see it. Then again, I’m clearly too old and too boring for Harajuku.
