A recurring theme in the Strange Boutique column has been the question of what has gone wrong with pop music in Japan. Amid discussions of the pernicious influence of advertising agencies, record industry conservatism in the face of declining sales, and the faceless, self-replicating Eurobeat monstrosity from out of Akihabara, there was one fundamental thing that Japanese pop seemed to have lost: The ability to make you go, "Wha...?"

For many, however, a pinprick of light emerged from the shade of not-quite-as-influential-as-it-was Tokyo fashion hub of Harajuku this July with the release of "Ponponpon," a song by fashion model-cum-singer Kyary Pamyu Pamyu (her label, Warner Music Japan, refuses to confirm her real name). Largely passing underneath the mainstream media's radar at first, it was a viral smash hit that annoyed people who deserved to be annoyed but delighted teenage girls, Belgians (where, along with Finland, it topped the iTunes electronic charts) and bemused netsurfers everywhere with the Technicolor blizzard of candy canes and eyeballs that made up its video, and its idiotically catchy "pon pon wei wei wei" chorus, courtesy of capsule/Perfume producer Yasutaka Nakata.

"I'm interested in exaggerating things," explains Kyary. "I'll be trying on wigs and I'll get interested in seeing what it would look like if I just put them all on at once. Or rather than just having one teddy bear, why not have me completely immersed in hundreds of them?"
