thumb|300px|minamoto no yorimasa portrait.    (1106â1180) was a prominent japanese poet whose works appeared in various anthologies. he served eight different emperors in his long career, holding posts such as hyÅgo no kami (head of the arsenal). he was also a warrior, leading the minamoto armies at the beginning of the genpei war. in the clashes between the minamoto and taira clans that had gone on for decades, yorimasa had tried to stay out of politics, and avoided taking sides. he did participate in the hogen rebellion in 1156. for a time, he was even friends with taira no kiyomori. during the heiji rebellion of 1160, he leaned just enough in favor of the taira that it allowed them to overthrow the minamoto. however, by the time he officially retired from military service in kiyomori's army in 1179, yorimasa had changed his mind about opposing his own clan. he entered the buddhist priesthood. in may 1180, he sent out an appeal to other minamoto leaders, and to temples and monasteries that kiyomori had offended. the genpei war began with the battle of uji in 1180. yorimasa led minamoto forces, along with warrior monks from mii-dera, in defending byÅdÅ-in. despite the monks' having torn up the planks of the bridge leading to the temple, the taira managed to break through the defenses, and take the temple. suffering defeat at uji, he committed suicide at byÅdÅ-in. minamoto no yorimasa's ritual suicide by seppuku is the earliest recorded instance of a samurai's suicide in the face of defeat. according to legend, his retainer took his head to prevent it from falling into the hands of the taira. he then fastened his master's head to a rock and threw it into the uji river so it could not be found. yorimasa's death poem was: : :umoregi no/hana saku koto mo/nakarishi ni/mi no naru hate zo/kanashikarikeru :like an old tree :from which we gather no blossoms :sad has been my life :fated to bear no fruitturnbull, stephen (1998). the samurai sourcebook. london: cassell & co. == see also ==  * seiwa genji ==references==  *sansom, george (1958). a history of japan to 1334. stanford, california: stanford university press. pp 278â9.  {{persondata | name = minamoto no yorimasa | alternative names = | short description = poet | date of birth = 1106 | place of birth = | date of death = 1180
