What is the name of this "Japanese style pop art"? - japanese cartoon style wedding invites

I watched the inspiring work spaces Flickr today and I saw one of the counters in the pictures had very nice with a wallpaper with a calendar on the floor and a cartoon character.

I could not read the name on the desktop background, but says something like "Cloud ---- S ', see, I was not able to read the rest of the word" to S'. Like a design in the Asian style.

If you have any ideas, any help appreciated! Thank you!
