Sanemoto was the 3rd son of Date Tanemune and supported Date Terumune in his campaigns. He was to be adopted by Uesugi Sadazane but resistance to this within both the Date and Uesugi houses not only caused the proposed union to be scrapped but triggered internal strife within the Date clan (the so-called Tenbun no ran). Sanemoto afterwards went on to be a valued retainer of his brother Harumune and nephew Terumune.
Son: Shigezane
