|Komoso / Yakko-san|
|This page attempts to
record what is known about the origin and history of the
origami design variously known as Komoso, Komuso or
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.
Komoso / Yakko-san is made from a square of paper that has been blintzed three times.
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.
Apart from Eric Kenneway's unsupported statement, the earliest evidence for the komoso design is from 1734 where the design appears in a Japanese book by Hayato Ohoka called 'Ranma Zushiki' which contains prints of decorations intended to enhance sliding room dividers. One of these prints shows a group of folded paper objects, among which are komoso, the traditional crane, the boat now commonly made from a newspaper hat and a tematebako cube. Komoso is pictured twice, once folded in half and once flat.
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 (https://origami.ousaan.com/library/historye.html) '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.'
I have not been able to discover any evidence as to when the non-folded-in-half version of the design was first called Yakko-san.
Yakko was a (perhaps derogatory) name given to the low-status servants of Samurai during the Edo period.
The Komoso design is listed on page 24 of the Kan no mado (usually dated to 1845) as one of the designs omitted from the ms on the basis that they are already well known.
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.'
In the modern era diagrams for Yakkosan (sic) appear in Isao Honda's 'The World of Origami' published in 1965 by Japan Publications.
Komoso / Yakko-san is very similar to other traditional designs such as the jacket from the Suit of Clothes and the Monkey in Maying Soong's 'The Art of Chinese Paperfolding'. I do not know if these designs derive from one another or are independent creations.
