Ba Shôkô was a Ryukyuan scholar-aristocrat who served as a performer on two Ryukyuan missions to Edo, in 1832 and 1842, as well as for the reception of a Chinese investiture mission to Ryûkyû in 1838.
He first traveled to Edo as a teenager, in 1832. According to some sources, he seems to have been regarded as the most talented of the gakudôji on that mission, and played quite a number of instruments, including dongxiao and other flutes, pipa, sanxian, and sanshin in uzagaku (chamber music) performances. At that time, his aristocratic title was Hamamoto satunushi.
Hamamoto was then promoted to the rank of satunushi peechin after his service on the Edo mission, and participated as a dancer in entertainments for the 1838 investiture mission. Promoted again to Hamamoto peechin, he then served as gakushi on the 1842 mission to Edo, accompanying and overseeing the new generation of teenage gakudôji.
