Yoriki

 were members of the "samurai" class of feudal Japan. "Yoriki" literally means "helper" or "assistant".
Description and history.
"Yoriki" assisted "daimyō" (feudal lords) or their designated commanders during military campaigns in the Kamakura and Muromachi periods. In the Edo period, "yoriki" provided administrative assistance at governmental offices. Among different "yorikis" were the "machikata yoriki", who were in charge of police under the command of the "machi-bugyō". Below the "yoriki" were the "dōshin". In the city of Edo there were about 25 "yorikis" working each for the two "machi-bugyō" offices.
