In 1185 (the first year of the Bunji era), MINAMOTO no Yoritomo, seeking to establish a system of Shugo (provincial constable) and jito (manager and lord of manor), was granted the Bunji Imperial Sanction to do so, simultaneously obtaining the authority to collect five sho (measures) of rice, for the purpose of supplying troops, from each tan (section) of each rice paddy on shoen (manor in medieval Japan) and Kokugaryo (territories governed by provincial government office) alike.
