Sanrio is a Japanese company founded by Shintaro Tsuji and is well known for their amazing and cute kawaii characters. They produce cartoons and movies around Hello Kitty, the small girl cat, My Melody, Kuromi, Keroppi, Pompompurin and many other characters. Did you know that Sanrio created over 450(!) characters since they started? We simply love them all and have created an awesome collection of coloring pages featuring these Sanrio characters. Their colors tend to be soft pinks, yellows, greens, etcetera, but why not print some coloring sheets and make the colors a bit bolder? The Japanese company Sanrio created Hello Kitty in 1974, and she is still its most famous character. Try coloring the same character twice, once in classic pastels and once in bold colors, and compare which you like best.
