The robe, which must be pure clothes, eliminates "e-jiki (=impure color) in accordance with the Buddhistic original idea.
Its form is similar to that of Emperor's "sai-e (=costume for Shintoism event)."
Only one difference is the style around the neck; the "soken" is "tari-kubi" (=square neck) "sai-e" is "maru-kubi (=round neck). " The features of this style are raw silk, non-pattern, and "hitoe with mo" (=detached skirt); "shitagasane" (=undergarment) is worn.
The length of "soken" is a little longer than a body length and the priest wears "sashinuki" (=divided skirt) like court nobles.
The priest in the photograph wears "gojo-gesa (=five-paneled Buddhist surplice)."
He has a "hi-ogi (=fan)" in his hand ["Chukei (=fan) replaced it after the Muromachi Era (1338-1573) and a "nenju (=rosary)" wearing "shitozu (=tabi socks)."
In the next time, "han-soken (=semi-raw silk robe)" in the same style and size of the original "soken" was designed.
The"soken (=plain silk robe) is called "cho soken" (=long soken), and there is "ate-iro "(=rank-indicating colors)" or sumi-iro" (=Japan ink black colors) as a color of it.
