He joined NHK television as an announcer and was selected to be part of the 3rd annual Toho New Face acting class in 1951. The following year, Koizumi made his acting debut in Toho Studios' Minato e kita otoko (1952). When the studios' sci-fi films took flight, Koizumi became a regular in those films, first starring as pilot hero "Shoichi Tsukioka" in Godzilla's first sequel Gojira no gyakushû (1955) . After appearing in the film, he became most notable for portraying doctors, professors or scientists. It is interesting to note that Koizumi appeared in Godzilla's 10th, 20th, and 30th anniversary films: Mosura tai Gojira (1964), _San daikaijû: Chikyu saidai no kessen (1964)_, Gojira tai Mekagojira (1974) and Gojira (1984), starring as a professor or a scientist. Koizumi is one of the few actors to appear in more than one Godzilla movie as the same character. He played "Professor Miura" in Mosura tai Gojira (1964) and _San daikaijû: Chikyu saidai no kessen (1964)_ (or "Professor Murai"). In the 1990s, Koizumi worked on a few films as producer and also served as host of Japan's long-running game show "Quiz Grand Prix."
