Chikafusa was a son of Kii Nagafusa who family had been minor daimyô in Buzen before submitting to the Ôtomo. Chikafusa threw in with the Shimazu when they invaded the Ôtomo's domain in 1586. He submitted to Toyotomi Hideyoshi the following year though he opposed Kuroda Yoshitaka (who had been given Buzen as his fief) and was murdered on Kuroda Nagamasa's orders.
