It’s not a surprise to me that Shintaro Tsuji, the founder of Tokyo-based company Sanio and creator of Hello Kitty is a billionaire. Face it, the Hello Kitty Kitty Cat is everywhere. It’s cute. It’s simplistic. Girls of all ages love it. I’m working on my own cartoon character as well, Good-Bye Kitty. It will be a billion times more irresistible than Hello Kitty. Mark my words.
