Shibukawa Takaaki served as a bushō during the Sengoku period. He was the Kyūshū tandai, or Commissioner of Kyūshū.
Takaaki is deemed the younger brother of Shibukawa Yoshinaga who served as the Kyūshū tandai or, alternatively, as the younger cousin or nephew. His relationship cannot be determined from genealogical records.
He may have received the character “aki” in his name from Shibukawa Yoshiaki, the founder of the Shibukawa clan but the origin of the other character in his name is unknown. It may have been from Shibukawa Yoshitaka (the adopted son of Shibukawa Yoshikane) but has not been confirmed. If Takaaki was the younger brother of Yoshinaga, then Yoshitaka was also a sibling. In this case, Takaaki would have been the only one of the three brothers not to receive the character “yoshi” in his name from the Ashikaga shōgun family.
The name of Shibukawa Takaaki has from the beginning appeared only in local historical records. After the death in battle of Yoshinaga in 1534, he called himself the Kyūshū tandai and raised arms. That same year, he was killed in the course of a defeat to the Ōuchi clan on Mount Kōun in Meinohama in Chikuzen Province. Whether this was a real person is not certain. An account of Chikuzen authored by a Confucian scholar in the early Edo period named Kaibara Ekiken notes that the tandaizuka, or burial mound of the tandai, in the Meinohama district of the Nishi ward in the city of Fukuoka in Fukuoka Prefecture was for the worship of Takaaki.
