At the gate of Shochiku’s Ofuna studio, so the story goes, someone once hung a sign that read: no dogs, no cats, no Mikuni. The actor it shut out had broken the cartel rule that chained Japanese stars to a single company, and he kept breaking things for the rest of his working life, his own teeth included. Then, past sixty, he signed with that same studio to play Su-san, the mild, fishing-mad company president of Tsuribaka Nisshi, and the country took him to heart as the most reassuring boss in its cinema. Rentaro Mikuni spent a lifetime refusing institutions and finished it as their gentlest face.

The man behind the stage name was Masao Sato, the son of an itinerant electrician, born in Ōta, Gunma Prefecture, and raised from infancy on the Izu Peninsula in Shizuoka. He quit middle school in his second year and, at fourteen, after a beating from his father, he stowed away on a ship out of Shimoda and landed in Qingdao. He drifted through China, Manchuria and Korea under a false age and came home through Busan at sixteen.

The war turned that restlessness into principle. Called up in 1943, at twenty, he tried to slip across to the continent from Karatsu with his girlfriend and was caught after his own mother, afraid the village would shun the family, handed one of his letters to the military police. He was shipped to the China front with a Shizuoka infantry regiment from which only a few dozen of more than a thousand men came home. In a year and eight months of service, by his own account, he never fired a single shot. After repatriation in 1946 he scraped by on odd jobs, black-market soap among them, until a Shochiku producer stopped him on a Ginza street in December 1950.

Keisuke Kinoshita gave him the lead in The Good Fairy in 1951, replacing Eiji Okada, who had been dropped in the Red Purge. The newcomer took his screen name from the character he played and won the Blue Ribbon award for best new actor. Within a year he had crossed to Toho to play opposite Toshiro Mifune in Hiroshi Inagaki’s Sword for Hire, and Shochiku fired him. In 1954, while he was playing Mifune’s weak-willed friend Matahachi in Inagaki’s Samurai I: Musashi Miyamoto, he signed for a Nikkatsu picture as well, and the studios branded him the first violator of the Five-Company Agreement. That is where the Ofuna sign comes from.

Being locked out pushed him toward independents and directors who wanted danger more than polish. For Kon Ichikawa he was Captain Inouye, the officer who keeps his platoon singing in The Burmese Harp. For Miyoji Ieki’s Stepbrothers he had ten teeth pulled, without anaesthetic, so that he could pass as the elderly husband of Kinuyo Tanaka, fourteen years his senior. Masaki Kobayashi cast him as Kageyu Saitō, the clan counsellor who presides over the cruelty at the centre of Harakiri, and as the ambitious samurai who abandons his wife in the “Black Hair” episode of Kwaidan. Tomu Uchida’s A Fugitive from the Past, in which he plays a man running for a decade from a crime born of postwar hunger, brought him the Mainichi Film Award for best actor.

Shōhei Imamura pushed him further. Shooting Profound Desires of the Gods on the island of Minami Daitō, he caught tetanus and nearly lost a leg; once treated, the actor Kanjūrō Arashi recalled, he went back to the island at his own expense. In Vengeance Is Mine he played the devout Catholic father of a serial killer, a performance that swept the 1979 supporting-actor prizes and made him the first actor to hold three Blue Ribbon awards.

The myth of total commitment has a less flattering side, and Japanese critics said so in his lifetime. Yoshio Shirai, a former editor-in-chief of Kinema Junpo, argued that Mikuni prepared so exhaustively that he tended to overplay, and that he needed a director strong enough to rein him in; Uchida, in Shirai’s view, was the best of them, while Ichikawa had trimmed the excess on The Burmese Harp. Colleagues paid for the method. Mitsuko Mori said he reduced her to tears more than once because his takes could swing far from what had been rehearsed; he replied that she had cried over a bad take, not over him. Off screen the same appetite for rupture ran through four marriages, a much-reported affair with the far younger actress Kiwako Taichi and a long estrangement from his son, the actor Kōichi Satō. The fearlessness audiences admired had a cost, and other people often carried it.

His own films kept running into the system he defied. A first attempt at directing, in 1963, was shelved because Toei, which held his exclusive contract, would not let one of its stars run an independent production; a second, shot in the deserts of Pakistan and Afghanistan in 1972, was never completed. He finally got there with Shinran: Path to Purity, adapted from his own novel about the founder of Jōdo Shinshū Buddhism. In 1987 it shared the Jury Prize at Cannes with Souleymane Cissé’s Yeelen.

A year later came the role that rewired his public image. In Tsuribaka Nisshi, Shochiku’s comedy about a hopeless salaryman, played by Toshiyuki Nishida, who teaches a stranger to fish without realising he is his own company’s president, Mikuni played that president, Su-san, for more than twenty years, until the final instalment in 2009. In the same stretch he played the tea master Sen no Rikyū for Hiroshi Teshigahara in Rikyu, and that performance, together with his Su-san, won him the Japan Academy Film Prize for best actor; he would take it twice more in the 1990s.

He shared the screen with Kōichi Satō several times, and the frost between father and son is said to have thawed after the birth of a grandson, Kan’ichirō, who became an actor himself after Mikuni’s death. His last film was Masato Harada’s Chronicle of My Mother, released in 2012, by which point he had appeared in more than 180 films. Rentaro Mikuni died on 14 April 2013 in a hospital in Inagi, on the western edge of Tokyo, at the age of 90; he had been born on 20 January 1923. He had asked not to be given a posthumous Buddhist name; he wanted to go as Rentaro Mikuni.

The films are still travelling. Janus Films opened a 4K restoration of Kobayashi’s original three-hour cut of Kwaidan at New York’s Film Forum in September 2026, after a French re-release in July, putting his faithless samurai back on large screens. Seen beside Su-san, that samurai makes the argument Mikuni’s whole career kept making: the actor who would belong to no studio could play belonging, and its betrayal, more convincingly than almost anyone in Japanese cinema.
