Nanbu Sanenaga

Nanbu Sanenaga (1222–1297) was a mid-Kamakura gokenin and the third son of Nanbu Mitsuyuki, enfeoffed with the Hakiri valley in Kai as its jitō. In 1238 he and his elder brother Sanemitsu escorted Shogun Yoritsune to Kyoto.

Around 1269 he became a leading patron of the monk Nichiren, and in 1274 welcomed the pardoned exile back to Hakiri and built his Minobu retreat. In 1281 he founded Kuon-ji and took vows as Nichien. His eldest son Sanetsugu's line became the Hachinohe Nanbu.
