In the Battle of Yashima in 1185, his achievement was so great that, with a single arrow, he dropped a folding fan as an aim hoisted onto the Taira clan's gunsen (battleship); consequently, he was rewarded with manors in five Provinces, including Tanba Province and Shinano Province from MINAMOTO no Yoritomo (Goka-no-sho manor in Tanba Province, Togu-no-sho manor in Wakasa Province, Ota-no-sho manor in Musashi Province, Sasage-no-sho manor in Shinano Province and Ebara-no-sho manor in Shitsuki County in Bichu Province)
元暦2年（1185年）の屋島の戦いでは、平氏方の軍船に掲げられた扇子の的を射落とすなど功績を挙げ、源頼朝より丹波国・信濃国など五カ国に荘園を賜った（丹後国五賀荘・若狭国東宮荘・武蔵国太田荘・信濃国角豆荘・備中国後月郡荏原荘）。
