Shimazu Munehisa

Shimazu Munehisa (1322–1340) was a Nanboku-chō-period warrior and the legitimate second son of the fifth Shimazu head, Shimazu Sadahisa. In 1338 he fought alongside his father in Kō no Moronao's army against the Southern Court general Kitabatake Akiie and won distinction.

He was the leading candidate to succeed as head of the Shimazu, but in 1340, aged nineteen, he died after falling from his horse while travelling in Satsuma. His early death opened the succession dispute that split the family into the Sōshū and Ōshū houses.
