Motobu Chōyū
Motobu Chōyū was an Okinawan karate master and elder brother of karateka Motobu Chōki.
Motobu Chōyū was born in Akahira village in Shuri, Okinawa. His father, Anji Motobu Chōshin was a descendant of Prince Shō Kōshin, the sixth son of Okinawan King Shō Shitsu.
Chōyū first learned the art of Udun-ti, also known as Goten-te,, which was passed down within the Shō royal family from father to eldest son. He then studied Shuri-te karate and koryū Japanese martial arts under the legendary karateka Matsumura Sōkon. In his final years, he was the head martial arts instructor to the last king of the Ryūkyū Kingdom, Shō Tai, succeeding Matsumura in that position.
