If you like things Japanese, you'll like Simone Legno, eventhough he's actually Italian. He created the brand, Tokidoki, which is a Japanese word meaning "sometimes." According to his site, Simone chose the word "sometimes" because "everybody waits for moments that change one's destiny." Tokidoki actually started as a personal website of his until he received an email from two entrepreneurs who offered him to transfer from Rome to LA to share his works to the world by creating the Tokidoki brand. Very tokidoki, indeed.
Looks like he's following the footsteps of famed Japanese artist Takashi Murakami, he already has a bag line with LeSportsac.
Check out his site at http://tokidoki.com.it. Be sure to launch the Flash site, I'm sure you'll love it. Very interactive, with games and all. So kawaii*, I love it!
*kawaii - Japanese term for cute
