Like a lot of 20-year-olds, Kae Takahashi has a page on U.S.-based MySpace, and there is no mistaking it for anyone else's.

It's got pictures of the funky Tokyoite modeling the clothes she designs in her spare time, along with her name, plus personal details and ramblings in slightly awkward English about her love life.

Switch to her site on Mixi, Japan's dominant online hangout, and her identity vanishes.
