What is "hananchi"

was the third and last king of the Okinawan kingdom of Hokuzan.

He became king in 1397, upon the death of his father. He sent missions to Korea announcing his succession, and to China seeking investiture and recognition as ruler of all of Okinawa. He was the most active of all kings of Hokuzan in diplomacy and trade with China, sending 14 tribute missions.

Hananchi is said to have had great military prowess, but to have relied too much on his personal strength and skill, to the detriment of his relationship with his retainers. In 1416, a number of his retainers, notably Gosamaru, defected to Chūzan. Shō Hashi, King of Chūzan, invaded Hokuzan and defeated Hanachi's army at Nago Castle. When his home castle of Nakijin Castle came under attack, the attackers were kept at bay for a time, as the castle itself was quite strong. However, Hananchi was betrayed by a retainer, Motobu Taihara, who opened the gates and allowed Shō Hashi's forces in. Defeated, Hananchi committed suicide.
