折り紙Origami

Origami (折り紙) is the art and technique of folding paper. It also refers to the two- and three-dimensional forms created in the process. The use of the term has been extended in modern times to include other materials such as metal, textiles, and it is also used in the biological sciences to describe folded structures like DNA.

Although the word origami has Japanese roots, the practice itself is universal and its origin remains unknown.

The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs which use cuts.

In the detailed Japanese classification, origami is divided into stylized ceremonial origami (儀礼折り紙, girei origami) and recreational origami (遊戯折り紙, yūgi origami), and only recreational origami is generally recognized as origami. In Japan, ceremonial origami is generally called "origata" (ja:折形) to distinguish it from recreational origami. The term "origata" is one of the old terms for origami.

The small number of basic origami folds can be combined in a variety of ways to make intricate designs. The best-known origami model is the Japanese paper crane.
