Isshiki Yoriyuki

Isshiki Yoriyuki (died 1337) was the second head of the Isshiki clan and a retainer of Ashikaga Takauji. He followed Takauji's break with the Kenmu government and retreat to Kyushu. In 1336 he held Nangō Castle, where Southern Court forces killed his steward.

In the fourth month of 1337 he advanced into Higo with his half-brother Noriuji, the new Kyushu tandai, and fell at the Battle of Inuzukabaru. He left a son, Yukiyoshi, but Noriuji succeeded him.
