Komoso / Yakko-san
This page attempts to record what is known about the origin and history of the origami designs known as Komoso and Yakko-san. Please contact me if you know any of this information is incorrect or if you have any other information that should be added. Thank you.

According to Wikipedia the komoso were a group of Japanese mendicant monks of the Fuke school of Zen Buddhism who flourished during the Edo period of 1600-1868. They were characterized by a straw bascinet (a sedge or reed hood named a tengai or tengui) worn on the head, manifesting the absence of specific ego. They were also known for playing solo pieces on the shakuhachi (a type of Japanese bamboo flute). These pieces, called honkyoku ("original pieces"), were played during a meditative practice called suizen (as opposed to reflective silent meditation) and 'that these monks 'were known first as komoso, which means "straw-mat monk". Later they became known as komuso, which means "priest of nothingness" or "monk of emptiness".

The 'hood' of the origami komoso design is presumably a representation of the straw hat that characterised these monks.


According to Koshiro Hatori in his History of Origami ( 'More familiar origami models such as Orizuru and Yakko-san have been depicted in ukiyoe or patterns for kimono since 18th century. To be accurate, Yakko-san did not exist at that time. They folded it in half and called Komoso.'

Yakko was a (perhaps derogatory) name given to the low-status servants of Samurai during the Edo period.


In the entry for Yakko-san in his Complete Origami (1987) Eric Kenneway calls Yakko-san 'a traditional Japanese clown' and states that 'according to one source, the folding method may have originated in the Muromachi Period (1394-1572).' Unfortunately the source of this information is not given.



This image from the picture book 'Keisei Ori Tsuru', by an unknown author, show a child being taught origami in a terakoya (a school for the children of commoners). The detail shows the child writing a poem on the wing of one Paper Crane while another Paper Crane and a Komoso lie on the other end of the table. Source: 'Oru Kokoro', the catalogue of an exhibition on paperfolding history held in Tatsuno City History and Culture Museum in 1999.



This print showing a Komoso lying on the floor comes from 'Onna Fuhzoku Tama kagami' by Nishikawa Sukenobu, which was published in 1723.



This print from a picture book by Mitsonubo Hasegawa, which can be dated to between 1716 and 1734, shows two children with a Komoso and a Paper Boat with Three Sails in a terakoya (a school for the children of commoners). Source: 'Oru Kokoro', the catalogue of an exhibition on paperfolding history held in Tatsuno City History and Culture Museum in 1999.


Komoso also appears in a Japanese book called 'Ranma Zushiki' which dates from 1734. One of these prints shows a group of folded paper objects. Komoso is pictured twice, once folded in half and once flat.



The print below is from the first volume of the illustrated book 'Ehon masu kagami' by Nishikawa Sukenobu, which was published in 1748. The subject of the print is the Hina Doll Festival and the ladies on the left are folding paper. There is a Komoso lying on the floor. Compare and contrast the similar print from 1723 above. There are a number of other similar prints which also show Komosos, but which I have not yet managed to verify or date. Details of these can be found on the page about Paperfolding in Prints by Nishikawa Sukenobu.



This print, which is said to be by the Japanese designer Nishikawa Sukenobu (1671-1750), shows women folding paper. Among the designs they have folded is Komoso. I have not been able to verify that this print is indeed by Nishikawa Sukenobu, but, if it is, it can date to no later than 1750 when he died.


In his article 'History of Origami in the East and the West before Interfusion', published in 'Origami 5: Fifth International Meeting of Origami, Science, Mathematics and Education', Koshiro Hatori writes that, 'The origami history researcher Satoshi Takagi one day bought a box containing many origami pieces. They are considered to have been folded by many persons in the house of Moriwaki from the middle eighteenth century through the nineteenth century ... the newer pieces are the traditional models we know well such as the orizuru and yakko-san.'

There is a note in the 'Kan No Mado', usually dated to 1845, which lists 'komuso' among those designs which are already well known and which are therefore not included in the ms (in order to spare the writer's brush). It seems reasonable to identify this with the Komoso design.



A picture of Yakkosan appeared in 'Kindergarten Shoho' (Preliminary Kindergarten) by Iijima Hanjuro, which was copyrighted on October 4th Meiji 17 (1884) and published by Fukuda Senzo in August of Meiji 18 (1885).



Two drawings of Yakkosan, one with an unusual head, appear in a monozukushi-e print, by an unknown artist, but said to be from the Meiji era. I have temporarily assigned it the date of 1912, the last year of that era, pending the discovery of more accurate information.



A drawing of Yakkosan appears in an illustration by Takei Takeo in a 1927 issue of the children's magazine 'Kodomo No Kuni' (The Land of Chicken).


In Western Europe / the USA


'The Art of Chinese Paper folding for Young and Old' by Maying Soong, which was published by Harcourt Brace and Company of New York in 1948, contains diagrams for Komoso although the design is called the 'Monkey'..



Diagrams for Yakkosan (sic) appear in Isao Honda's 'The World of Origami' published in 1965 by Japan Publications.
