The oldest za on record was the Yaseri-za (written as 八瀬里座 in Japanese), which was under the control of the Shoren-in Temple and comprised of fellers and palanquin bearers, and the Yaseri-za offered services to the Enryaku-ji Temple, which was the head temple of the sect that the Shoren-in Temple belonged to, and the Imperial Court.It eventually became the origin of the later Yase-doji (palanquin bearers for an emperor in Yase).
記録上に残る最古の座は青蓮院を本所とする八瀬里座で杣伐夫や駕輿丁によって構成されて青蓮院の本山である延暦寺や朝廷に奉仕を行い、後の八瀬童子の源流となった。
