This is such a huge bummer. I remember finding a localised copy of FRUiTS in a Hot Topic when I was 13 years old, and joining the Livejournal FRUiTS community soon after to try and pursue my dream of being one of these cool kids. I remember Shrinkle (founder of Sugarpill Cosmetics), Chubby Bunny, and Yume Warlock used to post there frequently, and I would be so jealous, dreaming about how my life (and my closet) would have looked like if I never moved away from California and could hang out with such fashionable folks.
FRUiTS will be sorely missed. Fast fashion, the current economy, and changing priorities of youth in Japan has been going down a path that lends credence to why FRUiTS is closing down. But hopefully we can keep thumbing through those back-issues and continue to wear flashy fashion until there's a resurgence.
