The glow stick business must be booming. Sure it was a staple of 1990s rave culture, but the modern idol-pop scene has taken to them at least threefold. And Yokohama Arena was filled with them last weekend at the @Jam Expo.
The country's biggest idol-group showcase featured a staggering 100 acts playing to a crowd of young women and men (OK, there were definitely more men) on seven different stages.
The @Jam festival, organized by Zepp Live and originally under the name Ota Jam, has spawned a number of offshoots: @Jam the Field, @Jam Next and the Kawaii Pop Fes. However @Jam Expo was the biggest undertaking so far.
