Plot

Junpei Ueki, a mid-level management employee at Toto Foods, returns to Japan aboard the Blue Clipper ocean liner after a two-year work assignment in Hong Kong.⁸ At his farewell and retirement party, his bosses send him packing with a modest pension, and that same night he vanishes.⁸ His wife Hisa and adult daughter Keiko turn to Keiko's newspaper reporter boyfriend, Shotaro Kasai, for help.⁸

The trail runs through a series of clues: a jade ring left with a bar, an out-of-character visit to a snack bar, a sun-worshipping sect, and a double-suicide attempt by an associate.⁸ The clues eventually point to a heroin-smuggling operation tied to a mysterious Sun God cult, led by a cult figure who is the hidden boss of the drug organization.³^•¹ A telegram from "Papa" claiming he has gone to a hot springs, followed by his return home acting strangely, deepens the ambiguity of whether Ueki is a kidnapping victim or a participant in the smuggling ring.⁸

The resolution is laid out in the film's Japanese-language summaries: the diligent middle-aged salaryman is bought by the drug organization and becomes involved in heroin smuggling, and when he realizes he has been deceived, he goes alone to the hideout, shoots the boss dead, sets fire to the hideout, and throws himself into the flames.⁹ Kasai, explaining Ueki's actions to his wounded daughter, says that everyone has a "sleeping beast" in their heart capable of terrible things when it awakens; Ueki's beast was woken by his resentment at being cast aside by the system he had devoted his life to, while the rule-breakers around him prospered.¹⁰

Themes and genre position

On paper, the film is a straightforward detective story, complicated by elements of the newspaper exposé, the youth movie, the middle-class shōshimin-eiga (in particular the contemporary films of Ozu Yasujirō), and even the horror genre.⁶ Its object of investigation is the missing father, and the film is structured around Junpei's absence.⁶ The critic Darragh O'Donoghue, an archivist at Tate and a contributing writer for Cineaste, reads the film as implying that Ueki and his middle-aged society are themselves the decadent representatives of the generation that brought Japan to militarism, fascism, and ruinous war, a generation whose corruption stifles the growth of their children.⁶

The film also engages with the work of Kurosawa Akira. It echoes the same year's The Bad Sleep Well, in which Toshiro Mifune joins a company to investigate his father's death, and, like Stray Dog (1949), it uses tropes of the American crime genre to explore post-war Japanese society.⁶ A DVD Talk reviewer notes that Ueki's expensive western-style house in the hills overlooking Yokohama resembles Mifune's house in Kurosawa's High and Low.⁸ Suspense melodramas about reporters investigating drug trafficking were in vogue in Japanese cinema of the late 1950s and early 1960s, with similar stories from most of the country's big studios.⁸

Place in Suzuki's career

The film belongs to Suzuki's early period at Nikkatsu, where he worked mostly on relatively small-scale B-movies for double-feature programs while employing techniques that broke against established film grammar, such as outlandish art direction and jarring cinematography and editing.¹¹^•¹² In these early crime films, including Take Aim at the Police Van (1960) and this film, Suzuki energized routine scripts with formal play: long mobile takes, audacious camera angles, outré compositions, dramatic lighting, and unexpected editing.⁶

Formal set-pieces. O'Donoghue identifies at least four moments in the film that elevate it beyond genre: Keiko's profile refracted by the vertical segments of an office windowpane during a conversation; a sequence in which Shotaro follows a drug dealer who then leaps onto a moving bus in which Shotaro is, impossibly, already standing; and two matching informant scenes in which the camera isolates the speaker and dramatizes their flashback on the screen above them, so that they talk like benshi, the storytellers who accompanied silent-era Japanese films.⁶ The projected-screen device echoes works of early cinema such as Ferdinand Zecca's Histoire d'un crime (1901); its use in a self-consciously contemporary film constitutes, in O'Donoghue's account, a moment of narrative and aesthetic rupture.⁶

Suzuki would famously claim that he made his first characteristic film with Youth of the Beast, released on 21 April 1963, after nearly a decade filming whatever scripts Nikkatsu threw at him.⁶ In the pre-1963 films, such set-pieces are subsumed into the wider formal organization of genre; thereafter they float free as the films' reason for being.⁶ The Sleeping Beast Within and Smashing the O-Line, a duo of gritty crime thrillers from 1960 featuring Hiroyuki Nagato, are distinct from the run of Suzuki titles anchored around actor Kōji Wada that followed later in 1960.¹³

Release and reception

Nikkatsu's official page records the film's Japanese release date as April 9, 1960, its length as 85 minutes, and its Nagoya-to-Yokohama shooting locations, including Yokohama's Chinatown and the port; the Japanese database allcinema gives the first release date as April 6, 1960.¹^•⁵ The Nikkatsu page also notes that the film was Suzuki's suspense piece dealing with a new religious movement (Nikkatsu-related cult, 日輪教) and that it marked Hiroyuki Nagato's first appearance in a Suzuki film.¹

Contemporary assessments vary. DVD Talk's review calls the film no better than average, with the character of Papa Ueki jerked around by the writers and a fiery climax the reviewer found unintentionally funny.⁸ Other critics emphasize the film's formal interest: a Letterboxd review singles out the double-exposure flashback imagery and the way the perspective shifts into the third act, giving the viewer knowledge the protagonist lacks.¹⁴ IMDb records a user rating of 6.7/10 from 244 votes.¹⁵ The film has circulated in restoration-era retrospectives, including a 2016 UCLA Film & Television Archive double bill and screenings at the Harvard Film Archive and the Melbourne Cinémathèque in 2016 and 2025.³^•¹⁶^•¹⁷
