The most kawaii things that a hip, self-respecting Harajuku or Shibuya girl can get her hands on are the accessories. Little cell phones (particularly with a cell phone charm - How men and women shop differently for cell phones) fly off the shelves - the littler the better.

Even more kawaii points if the accessories bear the face of Hello Kitty Purple Fairy - The symbol of all things Japanese-cute. And although Japanese school girls are forced to wear their uniforms to school, they have, of course, found ways to make them cute. They accessorize with precise little bows at the collar, and awesome loose socks that have to be glued into place.

Combine this with the cute little sailor uniforms and maybe a headband and pigtails, and it's no wonder men in Japan often have desire for schoolgirls.
