Jun'ya Koizumi

Junya Koizumi, born in 1937, was successfully elected to the Japanese House of Representatives early in his career, leveraging his father-in-law's electoral district in Kanagawa Prefecture. His first election victory was in 1937, and he subsequently played an important role throughout his political career.

During the Japanese invasion of China, Junya Koizumi joined the right-wing organization "Taisei Yokusankai." After World War II, he temporarily withdrew from the political arena and entered a period of silence. It wasn't until 1964 that he made a comeback, serving as the Defense Minister in the Ikeda Cabinet. He continued to hold this position during the Sato Cabinet.

While serving as Defense Minister, Junya Koizumi proposed a legal research plan called the "Three Arrows Research." This plan aimed to study Japan’s legal system in emergency situations ("in case of trouble") to better respond to national crises.

Details about his family background and personal education are not publicly available. Throughout his political career, Junya Koizumi is noted for his contributions to defense policy.
