27 June 1819), also known by the Chinese-style name Ba Kokushō (馬 克承), was a bureaucrat of the Ryukyu Kingdom.
[1] Ryōchū was born to an aristocrat family called Ba-uji Oroku Dunchi (馬氏小禄殿内).
He was pro-Japanese, and was a political ally of Makishi Chōchū and Onga Chōkō (恩河 朝恒, also known as Shō Jorin 向 汝霖).
However, Zakimi Seifu, a former Sanshikan who was impeached by Onga Chōkō and had to resign before, accused Makishi Chōchū of practice bribery at election.
Soon Oroku's unlawful act was exposed, he was removed from his position and arrested together with Makishi Chōchū and Onga Chōkō.
