Crane is not the national bird of Japan, but it is often shown as an image of Japan together with cherry blossoms and Mt. Fuji. Orizuru is a paper crane that is made from origami. Almost all Japanese people can make orizuru without looking at the instructions. I think most of us make it as a school activity. If you love Japan and you think you know a lot about Japan, then you should definitely know how to make orizuru (^_<)~☆
I offer origami classes. Please contact me for details.
