Wakisaka Yasuharu

Who was Wakisaka Yasuharu?

Wakisaka Yasuharu, sometimes referred to as Wakizaka Yasuharu, was a daimyo of Awaji Island who fought under a number of warlords over the course of Japan's Sengoku period.

Wakisaka originally served under Akechi Mitsuhide, a vassal of Oda Nobunaga. In 1581, he was one of several who led Nobunaga's troops in the Siege of Hijiyama. The following year, Akechi betrayed Oda Nobunaga and took his power and lands, but was defeated two weeks later at the Battle of Yamazaki.

Wakisaka then joined the victor, Hashiba Hideyoshi, who had become a conspicuous figure as a retainer of Oda Nobunaga. Following the Battle of Shizugatake in 1583, Wakisaka came to be known as one of the shichi-hon-yari, or Seven Spears of Shizugatake. These Seven would be among Hideyoshi's most trusted generals, especially in naval combat. Wakisaka was granted the fief of Awaji Island, worth 30,000 koku, in 1585. He was then made commander of part of Hideyoshi's fleet, taking part in Hideyoshi's 1587 campaigns in Kyūshū, the 1590 Siege of Odawara, and the invasions of Korea, which took place from 1592 to 1598.

Wakisaka led 1500 soldiers and landed on a Korean peninsula. He participated in the army and navy in various places in a Korean peninsula. His reward in this war is an increase of the territory of 3000 Koku.
