In 1955, Mishima took up weight training and his workout regimen of three sessions per week was not disrupted for the final 15 years of his life.
In his 1968 essay Taiyo to Tetsu (太陽と鉄, "Sun and Steel"), Mishima deplored the emphasis given by intellectuals to the mind over the body.
Mishima later also became very skilled at kendo, traditional Japanese swordsmanship.

After briefly considering a marital alliance with Michiko Shōda (正田美智子) (who later married Crown Prince Akihito and became Empress Emerita Michiko), Mishima married Yoko Sugiyama (瑤子)(daughter of Yasushi Sugiyama (杉山寧)) on June 1, 1958.
The couple had two children: a daughter named Noriko (紀子) (born June 2, 1959) and a son named Iichiro (威一郎) (born May 2, 1962).

While working on Kinjiki (禁色, "Forbidden Colors"), Mishima visited gay bars in Japan.
Mishima's sexual orientation was an issue that bothered his widow, and she always denied his homosexuality after his death.
In 1998, the writer Jirō Fukushima (福島次郎) published an account of his relationship with Mishima in 1951, including fifteen letters(not love letters) from the famed novelist.
Mishima's children successfully sued Fukushima for copyright violation on his letters.
The defendant side, the publisher Bungeishunjū insisted that "The content of these letters are practical correspondences, not copyrighted works", however, the plaintiff side wins by the judgment as below, "In addition to clerical content, these letters describes the feelings of Mishima's own works, his aspirations and views of life, in different words from the literary works."

In 1963, there was an incident called Yorokobi no koto Jiken (喜びの琴事件, "The Harp of Joy Incident") at the troupe Bungakuza (文学座) to which Mishima belonged.
It was that Haruko Sugimura (杉村春子) and other actors who were the Communist Party members refused to play a drama Yorokobi no koto (喜びの琴, "The Harp of Joy") Mishima wrote.
The main character of the drama was a person of Anti-communism and included in his dialogues, there was criticism about conspiracy of World communism.
Haruko Sugimura who was a follower of Mao Zedong led to refuse the play practice and appearance for ideological reasons, so Mishima left Bungakuza.

Tokyo Olympics in 1964, Mishima interviewed various sports every day and wrote the report articles as a correspondent for newspapers.
