No. Origami - is an art-form. It is the art of creating objects by using a (usually) single piece of paper. I, myself have been a 'folder' since I was around ten years old.
Oragami is popular in Japan because it is its starting region. there are millions of oragami that you can find on youtube if you watch a vid. or look on ggogle
