Specifically, there was military service during emergencies such as "Iza, Kamakura" (mobilization to Kamakura at the time of emergency), Obanyaku (the job of guarding Kyoto) to protect for dairi (Imperial Palace) or bakufu, Ikokukeigobanyaku and Nagato keigoban during later Mongol invasions, and Kanto-mikuji which was an economic burden.
具体的には、「いざ鎌倉」などに代表される緊急時の軍役、内裏の警護である大番役、幕府の警護である大番役、後の元寇の頃には異国警固番役や長門警固番役という形で行われ、また関東御公事と言われる経済負担もあった。
