Here's a unique looking papercraft, it's a cow character suited up in the a traditional Japanese armor and helmet riding on top of a giant fish. I couldn't understand what my translator was saying, it's got something to do with a Japanese celebration for the month of May? In any case, I can tell you that this is from the Mansei Co., Ltd. based in Kanda, Tokyo. The company went through a lot of phases to get to where it is now, it started as an electronics store, then became a restaurant selling high-grade meats, and currently as a luxury dining establishment - specializing in beef and beef related dishes.
They've got some other cute papercrafts, dioramas, and origami models on their site that you should check out, of course, all of them have the familiar cow theme to them. On their homepage, click on the "mansei club" icon to see the goods.
