Battle of Shizugatake
Following the Battle of Shizugatake in 1583, Nagayasu came to be known as one of the "shichi-hon-yari" (七本槍), or Seven Spears of Shizugatake. These Seven would be among Hideyoshi's most trusted generals. Owing to his achievement in that battle, he was rewarded with 3,000 additional koku.
