A couple who met briefly in Manchuria are reunited in Kobe five years later but find their joy short-lived amid the vagaries of the post-war society in Kon Ichikawa’s tragic romance, Nightshade Flower (夜来香, Ieraishan). The film takes its name from a song “夜来香” known as “Ieraishan” in Japanese, a transliteration of the Mandarin pronunciation (yèláixiāng) in katakana, which was released in a Chinese-language version in Shanghai in 1944 performed by Manchurian Japanese actress Yoshiko Yamaguchi (山口淑子) who also went by the names Ri Koran/Li Hsiang-lan (李香蘭) and later Shirley Yamaguchi at various times in her career. A song of lost love, it seems to echo a sense of despair among the wartime generation who cannot reconcile their pasts with the post-war present.
Akiko (Asami Kuji), a sex worker, first meets Seki (Ken Uehara), an army doctor, when he pulls her out of the way of an oncoming vehicle in a crowded market place in Northern China in June, 1944. As she is dressed in cheongsam and angrily shouts at him in Mandarin, he assumes her to be Chinese and carries on along his way while she remains ambivalent about the encounter especially as the sleeve of her dress has been torn. In any case, it’s clear that the situation has become precarious and most of the Japanese population are preparing for evacuation. The owner of the brothel where Akiko and her friend Gin (Harue Tone) are employed has hopes of carrying on her business further behind the lines where army bases are still in operation though the pair would prefer to head home as soon as possible, jumping off the repatriation truck organised for them by the madam with the intention of returning to the city and boarding the next one bound straight for the mainland.
But Gin falls off a cliff and injures her leg, leaving Akiko to go in search of a doctor incongruously rocking up at Seki’s medical clinic. Though she is originally unwilling to have him treat Gin, she soon comes around and the pair begin seeing each other with Akiko pledging to stay behind after putting Gin on a truck. Nevertheless the pair are separated during an air raid with Akiko believing that Seki has been killed in a direct hit to the shrine they were sheltering in when he left their foxhole to check on a crying baby. Five years later, Seki has returned to Kobe to look for Akiko but has had no luck while staying with the family of one of his men, Toshio (Yuji Kawakita), who has fallen into post-war despair and given up his promising future in medicine to peddle black market drugs with shady fixer Kameyama (Reikichi Kawamura).
The crisis comes when Seki realises he is losing his sight, apparently a delayed reaction to the head injury he sustained in Manchuria which was not fully treated due to the war’s end. Though he reunites with Akiko, he believes that he can no longer have a future with her because of his impending blindness and in fact that his life is now over. Akiko meanwhile has also fallen into despair. Believing Seki was dead she gave up on the idea of finding him and has returned to sex work, she and Gin working in a small backstreet bar and living in adjacent rooms of a rundown tenement block. Seki had always known that she was a sex worker, but she believes he may now reject her because she has failed to live up to the promise she made him of living a more “honest” life ironically because without him she had no reason to do so.
Meanwhile, Seki is intent of saving Toshio whom he had first met as a naive private openly crying over the death of his mother having picked up a venereal disease after losing his virginity to a sex worker in an attempt to overcome his grief. Toshio is an embodiment of the despair felt by young men who went to war as innocent teenagers and are filled with disillusionment and confusion. Though Toshio is luckier than most who struggle to find work in the difficult post-war economy, he came from a middle-class medical family and if he finishes his training of which he only has a year left he would inherit his father’s clinic, he no longer sees a future for himself and actively rejects his privilege as an act of self-harm by taking up with Kameyama and becoming involved with crime. He resents his father for remarrying soon after his mother died, taking the family maid as his second wife, and is reluctant to marry their nurse, Chiyo (Chiaki Tsukioka), who is also Kameyama’s younger sister, as everyone expects him to despite otherwise carrying on an affair with her which later results in a pregnancy. He says that he wants to earn his own living and be his own man but claims he cannot see the bright future Seki speaks of for him and continues along a dark path of crime and vice.
The constant rumblings of the train along with its flickering light strongly foreshadow the tragic denouement but also hint at the automatic motion of society that damns the trio and frustrates their attempts to move on from the war and find happiness in its aftermath. Even so, to modern eyes the motif of Seki’s literal blindness which robs him of the ability to perceive a happy future with Akiko cannot but seem a little ableist even as Akiko points out that many men lost their sight in the war but are living good lives with wives and children and that she does not see his disability as a barrier to their ability to make new lives for themselves in the post-war society much as he doesn’t regard her past in sex work as a reason to reject her.
Even so, Seki is dragged into the post-war morass after becoming involved with Kameyama in a futile attempt to save Toshio only to discover that Kameyama has betrayed them by getting them both to work on the same job as a payment for a debt taken out by Seki on Toshio’s behalf to free him from his life of crime. Ichikawa embraces a sense of melodrama with frequent closeups and an underlying theatricality, but also captures something of post-war confusion in the noirish fog that surrounds Akiko as she considers one last job to pay for probably useless medical treatment to save Seki’s sight. The cruelty of the ending is in its way too difficult to bear but perhaps apt for the view from 1951 in which the possibility of escaping the legacy of wartime corruption lies only in painful memories.
