I was poking around on the SanrioTown site and found out there’s a website dedicated to Hello Kitty’s 35th birthday which is November 1st at http://kitty35.com/english/.
It features these categories:
Many of the links go to Japanese sites like sanrio.co.jp, but you can usually find a button to switch to English. It looks like they’ll be adding more information as time goes by. The Events section I thought was really useful to see what shopping sales and other contests are going on.
In the Museum section, you can also see how Hello Kitty has changed over the years which is fun. But, even better, you can watch to movie of her transformation in the Movie section.
