According to an analysis of the Okehazama Incident in the Japanese history of warfare made by the Staff Headquarters of the Empire of Japan, based on the calculation that for every 10,000 koku the military service of 250 soldiers could be supported, it was estimated that Yoshimoto's territory produced a total crop yield of 1,000,000 koku and there were 25,000 soldiers in his army, but these were figures gained by padding each crop yield of the Suruga, Totomi and Mikawa provinces, which in reality were less productive, in addition to counting Owari Province as part of his territory.
