At that time, the government allowed provincial constables to requisition half of the taxes from the production of the year to obtain provisions in the midst of a nationwide disturbance (the Kanno Disturbance), aiming at the manors of the Province of Omi (provincial constable: Rokkaku clan), the Province of Mino (provincial constable: Yoriyasu TOKI) and the Province of Owari (provincial constable: Yoriyasu TOKI) all of which were the bloodiest battlefields in the disturbance.
当時、全国的な争乱（観応の擾乱）が続いており、兵糧調達のため、激戦地であった近江国（守護：六角氏）・美濃国（守護：土岐頼康）・尾張国（守護：土岐頼康）の本所領（荘園）を対象として、その年の収穫に限り、守護に年貢半分の徴発を認めた。
