Zombie Defense for Kids

This video was passed onto my from a buddy. It takes place on what I guess is a Japanese game show, where I guess the goal is messing up Japanese children forever. Some kids are interviewed in a house, only to go outside to encounter an elaborately choreographed zombie attack. They go back into the house, where the zombie follows them (only after sending a note that he's coming seconds before he arrives)...I just...why am I describing this?

If this is normal treatment of Japanese children, Pearl Harbor and anime suddenly make a ton more sense.
