Minamoto No Yoshiie (源 義家; 1039 – 4 August 1106), also known as Hachimantarō, was a Minamoto clan samurai of the late Heian period, and Chinjufu shogun (Commander-in-chief of the defense of the North).
The first son of Minamoto no Yoriyoshi, he proved himself in battle with the Abe clan in the Zenkunen War (Early Nine Years' War) and the Kiyohara clan in the Gosannen War (Later Three Years' War). Subsequently, he became something of a of samurai skill and bravery.
In 1050, Abe no Yoritokiie wave the post of Chinjufu shogun, as the Abe clan had for many generations; he was the chief commander of the defense of northern Honshū against the native Ezo (Ainu) people. Effectively, however, Yoritoki commanded the entire region, denying the official Governor any true power. As a result, Yoshiie's father was appointed both chinjufu shogun and governor, and Yoshiie traveled north with him to resolve the situation.
The campaign against the Abe clan lasted twelve years (nine, with three years truce). Yoshiie fought alongside his father in most if not every battle, including the Battle of Kawasaki and the Siege of Kuriyagawa. Abe no Yoritoki died in 1057, but his son Abe no Sadato took up command of his father's forces.
Yoriyoshi's first son, Hachimantarō, gave hot pursuit along the Koromo River and called out, 'Sir, you show your back to your enemy! Aren't you ashamed? Turn around a minute, I have something to tell you.' When Sadato turned around, Yoshiie said:
Koromo no tate wa hokorobinikeri ("Koromo Castle has been destroyed." or, alternatively, "The warps in your robe have come undone.")
Sadato relaxed his reins somewhat and, turning his helmeted head, followed that with:
toshi o heishi ito no midare no kurushisa ni ("Over the years its threads became tangled, and this pains me.")
