Andy Gray has been visiting Tokyo's Yoyogi Park and chronicling the characters he finds there on his charming photoblog Japanwindow. This week he puts up pictures of the 50s boy-gang wannabe Rockabilly guys, a group of joyful African-inspired drummers and hillbilly jug band Tokyo Limelight Circus. Marie Mockett at Japundit compares U.S. and Japanese teenage conformity and reflects on the social stereotypes of both countries.
