This study examines how origami has been implemented, practised, and developed in the early childhood education of Japan over the past 140 years. Historically speaking, paper-folding has been part of Japanese symbolic art, craft culture, and religious ceremonial artefacts since paper and paper-folding techniques were first imported from China during the seventh century. By the eighteenth century, paper-folding provided a form of mass entertainment in Japanese society. During the 1870s, paper-folding was dramatically transformed into a pedagogical tool within Japanese kindergartens after Friedrich Froebel's (1782-1852) kindergarten system and its curriculum was transferred to Japan from the West. "Papier-Falten" ("paper-folding") comprised an element of Froebel's Occupations -- which was a series of handiwork activities -- in his kindergarten curriculum, whereby various folding techniques and models were derived from European traditional paper-folding and introduced into a Japanese kindergarten curriculum that was associated with the concept of Froebel's kindergarten. Particularly seen in early childhood education in Japan, what we now call "origami" developed as a new form of paper-folding. This gradually emerged through the marriage of Western (German) and Eastern (Japanese) paper-folding cultures. The study highlights the benefits and uniqueness of cultural transmission and transformation when developing origami in early childhood education in Japan.
