Fujiwara no Motohira (藤原 基衡, 1105–1157) was the second ruler of Northern Fujiwara in Mutsu Province, Japan, the son of Fujiwara no Kiyohira and the father of Fujiwara no Hidehira.
[1] Fujiwara no Motohira is credited with expansion of Hiraizumi, the residence of Northern Fujiwara.
In particular, he founded Mōtsū-ji, and his wife built Kanjizaiō-in which was adjacent to Motsu-ji.
Both sites survived, though all the buildings from the Heian period were lost, and are currently listed as constituents of a World Heritage Site, Historic Monuments and Sites of Hiraizumi.
[1][2] He also expanded Chūson-ji, where he was buried, along with his father and his son.
