In the 1960s, Takechi entered the film industry by producing controversial soft-core theatrical pornography. His 1964 film Daydream was the first big-budget, mainstream pink film released in Japan. After the release of his 1965 film Black Snow, the government arrested him on indecency charges. The trial became a public battle over censorship between Japan's intellectuals and the government. Takechi won the lawsuit, enabling the wave of softcore pink films which dominated Japan's domestic cinema during the 1960s and 1970s. In the later 1960s, Takechi produced three more pink films. In the 1980s he again started pushing boundaries by featuring real unsimulated sex in the 4 movies he directed during this period.
