Introduction of origami

Offsetting paper is an artistic activity that involves folding paper into different shapes. Origami is not limited to the use of paper. Origami enthusiasts around the world use a wide variety of materials such as tin foil, napkins, and acetate sheets while adhering to folding norms.

Origami originated in China around the 1st or 2nd century A.D. and was introduced to Japan in the 6th century, through which it spread around the world. It is also believed that origami originated in Japan and Spain.

The combination of origami and the natural sciences not only served as a teaching aid in architectural schools, but also led to the development of origami geometry as a branch of modern geometry. Origami was both a toy and an activity of the mind; a symbolic means of peace and remembrance as well as a pastime.

Paper has been excavated from sites in China during the Western Han Dynasty, but there is no evidence that origami existed at that time. In Japan, origami is said to have begun in the Heian period (around 794-1185 AD), but the earliest documented record of origami is a haiku written by the Edo period haiku poet Ihara Nishizuru in 1680. The haiku mentions an origami work called "male and female butterflies".
