While many origami books include sections on the art’s history, the majority of these narratives lack thorough examination of the subject. Notable investigations by scholars such as Okamura into the history of Japanese origami often receive limited attention beyond Japan. In addition, despite the efforts of researchers like Lister and others, our understanding of the European origami tradition remains inadequate. Consequently, pseudohistories regarding the origin of origami persist both outside and inside the origami community. This paper delves into the theories surrounding the emergence of origami in both Japan and Europe, and through critical evaluation demonstrates that several of these theories, particularly those asserting that origami originated as early as the fifteenth century or before, lack historical validity and should be considered pseudohistories.
