- Died: 1545
- Shôni retainer
Yorichika nominally served the Shôni of western Kyushu but in 1544 he secretly communicated with Ôuchi Yoshitaka and plotted against Ryûzôji Iekane. He attacked Iekane's household and killed a number of its members, including Ryûzôji Chikaie (father of Ryûzôji Takanobu). Iekane fled to Chikugo and returned the following year. Yorichika's forces were defeated and Yorichika was killed.
