The Only Son (一人息子)

The Only Son (一人息子, Hitori musuko) is a 1936 Japanese drama directed by Yasujirō Ozu and his first sound film, telling the story of a widowed silk-mill worker who sacrifices everything to give her son an education, and finds his life in Tokyo far short of her hopes.¹ Produced by Shochiku, it is regarded as one of the director's finest works and as a forerunner of his later family dramas such as Tokyo Story (1953).¹^•²

Story and themes

In 1923, the widowed Otsune works in a silk mill in Shinshu, a textile region near Nagano, and has just concluded that her son Ryosuke will have to forgo an expensive higher education. His teacher Okubo visits to congratulate her on agreeing instead to pay the boy's way through high school and college; she is angry with her son for deceiving her about his ambitions, but goes along with the plan.⁶ Twelve years later she travels to Tokyo expecting to see his success, and is met with a series of shocks: a daughter-in-law and grandson she knew nothing about, and the discovery that Ryosuke holds only a low-paying job teaching mathematics at a night school. Okubo himself now runs a forlorn tonkatsu (fried pork cutlet) restaurant in an unmetropolitan part of town.⁶

The film is about the failure of risshin shusse, "getting on": the dashed hopes of those who invested more than they could afford in education, and in the image of Tokyo as a beacon of opportunity. In 1936 the great zaibatsu conglomerates hired only graduates of Japan's most prestigious universities; others faced a choice between unskilled, low-paying work and humble self-employment.⁶ The drama hinges on two frank conversations between mother and son about work, morale, and prospects, one set against a garbage-burning plant, one in the middle of the night in Ryosuke's shabby rented rooms.⁶ The Japanese Film Festival synopsis frames the same bond as a struggle against rigid class boundaries and the hardships of urban life.²

Structure and setting

The film's 13-year span takes in a detailed portrait of rural life and a rare depiction of the silk-spinning industry, then a vision of Tokyo quite different from the nostalgic downtown or jazzy metropolis of Ozu's earlier films. David Bordwell, the film scholar whose Ozu and the Poetics of Cinema (BFI/Princeton, 1988) discusses the work, describes this Tokyo as "new, raw," a cluster of ramshackle tenements against factories and wasteland; the sightseeing tour mother and son make is only reported, while the outing actually shown has them squatting before the city garbage-treatment plant.⁸

Ozu's playfulness persists. A classroom scene in which Ryosuke teaches circles and right angles is covertly an exposition of Ozu's own method for filming domestic interiors: he placed characters in an imaginary circle and framed shots from angles 45 degrees apart on its circumference. Shots of the fluttering tonkatsu flag outside Okubo's restaurant are always seen from behind, so the hiragana characters read backward.⁶

Sound, and the Kamata shoot

Shochiku had made talkies with the Tsuchihashi Sound System since 1933, but Ozu had promised to use a sync-sound system invented by his regular cameraman Mohara Hideo, and refused to record dialogue with the Tsuchihashi technology. He and Mohara had first tried Super Mohara Sound in brief sequences in the 1935 kabuki documentary Kagamijishi; The Only Son was its first full-scale deployment. Ozu's refusal strained relations between Shochiku and Tsuchihashi, which had threatened to end its contract, and producer Kido Shiro had to intervene personally.⁶

The resolution shaped the production: the shoot was moved from the new Ofuna studio to the recently vacated Kamata studio, where Ozu had worked since joining Shochiku as a camera assistant in 1923. Kamata had no soundproofing, and demolition had already begun, so Ozu rebuilt to create a makeshift soundstage while filming was plagued by neighborhood noise. Shochiku's own database notes that the film became, by chance, the last ever shot at Kamata.⁶^•³ The Shochiku database also lists the Japanese release date as 25 September 1936, while the Eiga.com database gives 15 September 1936; the sources disagree on the exact day.³^•⁴

One scene carries a quiet joke about the new technology itself: Ryosuke takes his mother to the cinema, where the film shown is Willi Forst's directorial debut Unfinished Symphony, a biopic of Schubert, apparently screened without Japanese subtitles or a benshi narration. Otsune, unimpressed by her first talkie, keeps dropping off while her embarrassed son pretends to enjoy it. In a year when Japan screened 270 Hollywood films and only 25 from Germany, the choice of a German film was clearly deliberate.⁶

Place in Ozu's career

By 1936 Ozu, then 32, had directed more than thirty silent films for Shochiku, and his work had appeared regularly since 1930 in the annual Best Ten poll of the magazine Kinema Junpo. The Only Son placed 4th in the 1936 poll.⁶^•⁷ Critic Tony Rayns, a London-based specialist in East Asian film cultures and recipient of Japan's Foreign Ministry Commendation in 2008, reads the film's irony as marking a turn in Ozu's work: the prevalence of single parents in his films from this point on reflects, in Rayns's view, the death of Ozu's own father in 1934.⁶

Bordwell notes that with dialogue Ozu was already practicing the restraint he would maintain for the next 25 years, never cutting so as to break a character's line, not even by a syllable, and that the film introduces several of his characteristic sound techniques, including music that runs across two scenes.⁸ The Criterion Collection released the film on DVD as Spine #525, paired with There Was a Father (1942) in a two-disc set, with new interviews with the scholars Tadao Sato, David Bordwell, and Kristin Thompson and a booklet essay by Rayns.¹^•⁹
