He played with many of the most important Japanese free groups and musicians during the seventies, such as ESSG and those of Masahiko Togashi, Motoharu Yoshizawa and Masayuki Takayanagi.
[1] During his younger years, he spent time in the bands of players such as Charlie Ishiguro and Hisashi Sakurai.
In 1968, he joined the Motoharu Yoshizawa Trio, which created fresh free sounds in Japanese jazz.
After Togashi's accident, Takagi played briefly with Masayuki Takayangi's New Direction Unit and in a duo with percussionist Sabu Toyozumi.
Takagi recorded very few albums as a leader over the course of his career, but he was highly valued as a collaborator by many Japanese jazz, rock and avant-garde musicians.
