===Recreational origami===
====1500s－1800s====
It is not certain when play-made paper models, now commonly known as origami, began in Japan. However, the ''[[Japanese sword mountings#Components|kozuka]]'' of a [[Japanese sword]] made by Gotō Eijō (後藤栄乗) between the end of the 1500s and the beginning of the 1600s was decorated with a picture of a crane made of origami, and it is believed that origami for play existed by the [[Sengoku period]] or the early Edo period.<ref name ="kyushu2">{{cite web|url=https://guides.lib.kyushu-u.ac.jp/origami/-mid18C|archive-url=https://web.archive.org/web/20210507224948/https://guides.lib.kyushu-u.ac.jp/origami/-mid18C|script-title=ja:折り紙の歴史と現在: 戦国～江戸中期|language=ja|publisher=Kyushu University Library|archive-date=7 May 2021|access-date=14 November 2022}}</ref>

In 1747, during the [[Edo period]], a book titled ''Ranma zushiki'' (欄間図式) was published, which contained various designs of the ''[[Transom (architecture)|ranma]]'' ([[:ja:欄間]]), a decoration of [[Japanese architecture]]. This included origami of various designs, including paper models of cranes, which are still well known today. It is thought that by this time, many people were familiar with origami for play, which modern people recognize as origami. During this period, origami was commonly called ''orikata'' (折形) or ''orisue'' (折据) and was often used as a pattern on [[kimonos]] and decorations.<ref name ="kyushu2"/>

[[File:Origami Hyakkaku (One hundred cranes).jpg|thumb|''Hyakkaku''  (百鶴, One hundred cranes) is one of the works featured in ''Hiden senbazuru orikata''. It is made by folding a single sheet of paper, and its production method has been designated an Intangible Cultural Property of [[Kuwana, Mie|Kuwana City]].]]
''Hiden senbazuru orikata ([[:ja:秘傳千羽鶴折形]])'', published in 1797, is the oldest known technical book on origami for play. The book contains 49 origami pieces created by a Buddhist monk named Gidō ([[:ja:義道一円|:ja:義道]]) in [[Ise Province]], whose works were named and accompanied by ''[[kyōka]]'' (狂歌, comic ''[[tanka]]'') by author Akisato Ritō (秋里籬島). These pieces were far more technically advanced than their predecessors, suggesting that origami culture had become more sophisticated. Gido continued to produce origami after the publication of his book, leaving at least 158 highly skilled masterpieces for posterity. In 1976, [[Kuwana, Mie|Kuwana City]] in [[Mie Prefecture]], Gido's hometown, designated 49 of the methods described in the ''Hiden senbazuru orikata'' as Intangible Cultural Properties of [[Kuwana, Mie|Kuwana City]]. Kuwana City has also certified qualified persons who are able to correctly produce these works and have in-depth knowledge of the art. Kuwana City has published some of the origami production methods on [[YouTube]].<ref name="kyushu3"/><ref name="kuwana">{{cite web|url=http://orizuru49.com/en/|archive-url=https://web.archive.org/web/20221118035100/http://orizuru49.com/en/|title=Paper Cranes that connect People|publisher=[[Kuwana, Mie|Kuwana City]]/MIRAI NEXT Co., Ltd.|archive-date=18 November 2022|access-date=18 November 2022}}</ref><ref>{{Cite book|title=Origami 5: Fifth International Meeting of Origami Science, Mathematics, and Education|last=Wang-Iverson|first=Patsy|publisher=A K Peters/CRC Press|year=2011|isbn=9781568817149}}</ref>

From the late Edo period to the [[Bakumatsu|Bakumatu period]], origami that imitated the six legendary Japanese poets, ''[[rokkasen]]'' (六歌仙) listed in the ''[[Kokin Wakashū]]'' (古今和歌集)  compiled in the 900s and the characters in ''[[Chūshingura]]'' became popular, but today they are rarely used as subjects for origami.<ref name="kyushu3">{{cite web|url=https://guides.lib.kyushu-u.ac.jp/origami/late18C-mid19C|archive-url=https://web.archive.org/web/20210507220346/https://guides.lib.kyushu-u.ac.jp/origami/late18C-mid19C|script-title=ja:折り紙の歴史と現在: 江戸後期～幕末|language=ja|publisher=Kyushu University Library|archive-date=7 May 2021|access-date=14 November 2022}}</ref>

In Europe, there was a well-developed genre of [[napkin folding]], which flourished during the 17th and 18th centuries. After this period, this genre declined and was mostly forgotten; historian Joan Sallas attributes this to the introduction of porcelain, which replaced complex napkin folds as a dinner-table status symbol among nobility.<ref>Joan Sallas. "Gefaltete Schönheit." 2010.</ref> However, some of the techniques and bases associated with this tradition continued to be a part of European culture; folding was a significant part of [[Friedrich Fröbel]]'s "Kindergarten" method, and the designs published in connection with his curriculum are stylistically similar to the napkin fold repertoire.  Another example of early origami in Europe is the "pajarita," a stylized bird whose origins date from at least the nineteenth century.<ref>{{Cite web|url=https://www.britishorigami.org/cp-lister-list/pajarita/|title="The ''pajarita''"|last=Lister|first=David|website=British origami|access-date=29 October 2022}}</ref>

====Since 1800s====
When Japan opened its borders in the 1860s, as part of a modernization strategy, they imported Fröbel's Kindergarten system—and with it, German ideas about paperfolding. This included the ban on cuts, and the starting shape of a bicolored square. These ideas, and some of the European folding repertoire, were integrated into the Japanese tradition. Before this, traditional Japanese sources use a variety of starting shapes, often had cuts, and if they had color or markings, these were added after the model was folded.<ref>"History of Origami in the East and West before Interfusion", by Koshiro Hatori. From Origami^5, ed. Patsy Wang Iverson et al. CRC Press 2011.</ref> In Japan, the first kindergarten was established in 1875, and origami was promoted as part of early childhood education. The kindergarten's 1877 regulations listed 25 activities, including origami subjects. ''Shōkokumin'' (小国民), a magazine for boys, frequently published articles on origami. ''Origami Zusetsu'' (折紙図説), published in 1908, clearly distinguished ceremonial origami from recreational origami. These books and magazines carried both the traditional Japanese style of origami and the style inspired by Fröbel.<ref name="kyushu4">{{cite web|url=https://guides.lib.kyushu-u.ac.jp/origami/moderntimes|archive-url=https://web.archive.org/web/20210507225636/https://guides.lib.kyushu-u.ac.jp/origami/moderntimes|script-title=ja:折り紙の歴史と現在: 明治・大正|language=ja|publisher=Kyushu University Library|archive-date=7 May 2021|access-date=14 November 2022}}</ref>

In the early 1900s, [[Akira Yoshizawa]], [[Kosho Uchiyama]], and others began creating and recording original origami works. Akira Yoshizawa in particular was responsible for a number of innovations, such as [[wet-folding]] and the [[Yoshizawa–Randlett system|Yoshizawa–Randlett diagramming system]], and his work inspired a renaissance of the art form.<ref>{{cite web|url=https://www.nytimes.com/2005/04/02/arts/design/akira-yoshizawa-94-modern-origami-master-dies.html|title=Akira Yoshizawa, 94, Modern Origami Master, Dies|author=Margalit Fox|work=[[The New York Times]]|date=April 2, 2005}}</ref>

In 1974, origami was offered in the USSR as an additional activity for elementary school children.<ref>И. С. Могилевская. Складывание из бумаги // журнал "Начальное образование", № 7, 1974. стр.39</ref>

During the 1980s a number of folders started systematically studying the mathematical properties of folded forms, which led to a rapid increase in the complexity of origami models.<ref>Lang, Robert J. "Origami Design Secrets" Dover Publications, 2003.</ref>

Starting in the late 20th century, there has been a renewed interest in understanding the behavior of folding matter, both artistically and scientifically. The "new origami," which distinguishes it from old craft practices, has had a rapid evolution due to the contribution of computational mathematics and the development of techniques such as ''box-pleating'', ''tessellations'' and ''wet-folding''. Artists like [[Robert J. Lang]], [[Erik Demaine]], [[Sipho Mabona]], [https://giangdinh.com Giang Dinh], [http://www.origami-artist.com Paul Jackson], and others, are frequently cited for advancing new applications of the art. The computational facet and the interchanges through social networks, where new techniques and designs are introduced, have raised the profile of origami in the 21st century.<ref>{{cite web |last1=Gould |first1=Vanessa |title=Between the Folds, a documentary film |url=https://www.vanessagould.com}}</ref><ref>{{cite book |last1=McArthur |first1=Meher |title=Folding Paper: The Infinite Possibilities of Origami |date=2012 |publisher=Tuttle Publishing |isbn=978-0804843386}}</ref><ref>{{cite book |last1=McArthur |first1=Meher |title=New Expressions in Origami Art |date=2020 |publisher=Tuttle Publishing |isbn=978-0804853453}}</ref>
