sisaku
Sisaku refers to a traditional Japanese art form of paper folding that predates modern origami. While the exact origins are debated, sisaku likely developed during the Heian period (794-1185) and was initially practiced by the aristocracy and in religious ceremonies. Unlike the more structured and often figurative nature of modern origami, sisaku focused on simpler, more abstract folds, often using square pieces of paper. These folds were frequently used for decorative purposes, such as adorning gifts or creating symbolic objects for rituals. The term "sisaku" itself is believed to derive from words related to folding and arrangement. Over time, the practice evolved, and many of its techniques and principles were absorbed into the development of what is now recognized as origami. While sisaku as a distinct practice is less commonly discussed today, its influence is an important part of the historical lineage of paper folding arts in Japan.
