His work in anime is particularly notable for the many villains and eccentric characters he brought to life. He became synonymous with comedic villain roles in the Time Bokan series, most famously as Dokurobee in Yatterman, where his catchphrase Oshioiki da be became a well-known expression in Japan.

Beyond anime, Takiguchi was a prolific voice actor in dubbed versions of foreign live-action and animated works.

Pepper in the James Bond films Live and Let Die and The Man with the Golden Gun. He also dubbed iconic characters such as The Joker (Caesar Romero) in the 1960s Batman series, Grampa Simpson in The Simpsons, Krang in Teenage Mutant Ninja Turtles, and Uncle Traveling Matt in Fraggle Rock. His narration work, particularly for the long-running travel documentary series Burari Tochūgesha no Tabi, made his voice a familiar and comforting presence in Japanese households.
