Kimura Shigenari (木村 重成, 1593 – June 2, 1615) was a Japanese samurai of the early Edo period.
In recognition of his distinguished deed in that battle Hideyori bestowed on him a testimonial that acclaimed him as the “peerless hero of the nation”, together with a short sword made by Masamune, the famous swordsmith.
A year later, during the Summer Siege of Osaka, he left the castle walls, leading the main force of the Toyotomi army and fought against Ii Tadataka's troops.
In that battle, Shigenari wore a suit of armor called kozane made of gold and silver scales, with a white horo (a mantle meant to disrupt the flight of oncoming arrows), and rode a black horse.
He was beheaded, and the head was taken to Tokugawa Ieyasu, who saw it neatly trimmed on the forehead and the hair tidily cut and perfumed with incense.
