Spoilers

Plot

The story opens in a Tokyo no-tell hotel, where a man and a woman lie dead in what appears to be a forced lovers' suicide. Police identify the man as Koichi Takeshita, a serving detective.¹ Days later, a drifter known only as "Joe" begins beating up petty criminals in the entertainment districts. His nerve earns him a job as bodyguard and trigger man for the Nomoto group, one of two gangs facing off against each other.⁴

Joe is in fact a former detective, the dead officer's colleague, working undercover to find the truth behind the death.² He secretly contacts the rival Sanko group as well, playing the two organizations against each other while he continues his own investigation.² Within the Nomoto organization he finds layers he cannot account for, including what appears to be a large call-girl operation connected to narcotics and run by a hidden controller.¹ As double and triple crosses accumulate, the plot serves mainly as a frame for Suzuki's escalating visual inventions.³

Production and style

The film was Suzuki's second collaboration with Joe Shishido, the baby-faced, chipmunk-cheeked actor who became one of his most iconic performers and who also starred in Branded to Kill (1967).³ Suzuki and Shishido had already paired in Detective Bureau 2-3: Go to Hell Bastards! in January 1963, another Oyabu adaptation, and Youth of the Beast followed the same year.⁵ According to Suzuki, the picture began shooting as an adult film and was changed to a general-audience film partway through production.⁵

The opening sequence is the film's most cited invention: it is the first Suzuki film to begin in black and white and then turn suddenly to the cranked-up pop-art color for which he became known, with a single flower in a vase dyed crimson against the monochrome frame.³ Later set pieces include a cabaret whose interior is visible through a one-way mirror and a yakuza office installed behind a movie theater's screen.² The entertainment writer Toshiaki Sato, an entertainment-film researcher, notes that the story pattern, an undercover protagonist playing two hostile organizations against each other, follows the same mold as Kurosawa's Yojimbo (1961) and the 1960 Toho adaptation of Oyabu's Confrontation in the Underworld, and that the film's pleasure comes from the fusion of routine Nikkatsu action-movie craft with the visual play that would soon explode across Suzuki's later work.⁵

Suzuki himself dated his arrival as a stylist to this period: he claimed that 1963 was the year he truly came into his own, and Youth of the Beast is counted among his breakthroughs.⁶ He had joined Nikkatsu in 1954 and turned out dozens of low-budget crime and action pictures there until his dismissal after Branded to Kill in 1967; the style consolidated in films from Youth of the Beast (1963) through Tattooed Life (1965), Tokyo Drifter (1966), and Branded to Kill (1967) came to be called "Suzuki aesthetics."⁷

Reception and rediscovery

The film was almost completely ignored by Japanese critics on release and did not reach the United States until about 30 years later; even then it went largely unnoticed until a new generation of enthusiasts discovered it in the 21st century.³ The critic Nobuhiko Kobayashi, writing in the July 1963 issue of Eiga Hyoron, documented how coldly the film had been received at the time, recording that it flopped at the box office and was entirely ignored by film journalism.⁸ Later assessments reversed this verdict: the New York Times critic Manohla Dargis described the film's mode as "Japanese cinema in all its frenzied, voluptuous excess," and Howard Hampton's 2005 Criterion Collection essay saw in it "a director hitting his stride, full of devil-may-care assurance and try-anything imagination."³

The film's international standing grew through retrospectives. The Film Society of Lincoln Center programmed it in "Action and Anarchy: The Films of Seijun Suzuki" in November 2015, screening a 35 mm print courtesy of the Japan Foundation.⁶ In 2012 the Hong Kong action director John Woo announced he would remake the film as Day of the Beast; the project has not been produced, most likely because of the demise of Woo's production company with producer Terence Chang.³ Suzuki's work has influenced directors including Jim Jarmusch and Quentin Tarantino.³
