The old, dark house fetches up in Japan in Hajime Sato’s slice of weird, gothic horror The Ghost of the Hunchback (怪談せむし男, Kaidan Semushi Otoko, AKA House of Terrors). Long in circulation only in an Italian dub, Sato’s B-movie romp owes an obvious debt to Mario Bava but also to similarly themed gothic chillers such as Robert Wise’s The Haunting somewhat repurposing the central nexus of the cursed mansion as a black hole of morality sucking into its orbit the sinners of the post-war society each it seems both victims and embodiments of their times.
Opening in true gothic fashion with lightning and a full moon, Sato zooms in to a strangely creepy yet ordinary Western-style villa where the soon-to-be widowed Yoshie (Yuko Kusunoki) is woken from a dream in which she had a premonition that her husband, who we learn has been in a vegetative state for some time, had something he desperately wanted to tell her. Shinichi has indeed passed away while apparently imprisoned under the care of his father, Munekata (Kazuo Kitamura), a psychiatrist who seems less than moved by his son’s death describing it as the least he could do to repay the debt he owed to his parents. It seems that Shinichi had been in the hospital following an “incident” some time previously and though Munekata insists that his brain had been “destroyed”, younger doctor Yamashita (Shinjiro Ebara) echoes Yoshie’s dream in informing her that immediately before he died it seemed that Shinichi, who had long been mute, was desperately trying to tell him something. Meanwhile, Yoshie begins hearing strange noises emanating from the coffin and opens it to find a chrysanthemum clenched between her husband’s teeth.
After the funeral, she’s visited by a lawyer claiming that Shinichi entrusted a key to him to be given to his wife in the event of his death along with the deed for a mountain villa where “the incident” took place. Later, everyone comes to the conclusion that what Shinichi wanted to tell them was not to go to the mansion, but of course what else was Yoshie supposed to do other than investigate. A classic gothic estate swathed in fog and hidden behind ornate iron gates, the remote country house also turns out to have a hunchback custodian (Ko Nishimura) as well as a weird, demonic statue standing inconveniently in the hallway. Soon after arriving Yoshie is attacked by a crow, told of “the incident” by the hunchback, and begins to hear strange noises including disembodied laughter before she is eventually joined by Munekata, Yamashita, and her niece Kazuko (Yoko Hayama).
Yamashita tries to rationalise that the noises are just the normal kinds of creaking born of “deformation” as a building naturally ages, literally becoming warped with time, while the stress of living in such an environment, he claims, can eventually drive one mad. He’s come along to investigate believing that Shinichi’s illness is connected to the mansion. Yet the old, dark house in this case is somewhat divorced from its gothic roots in being transported to Japan where it is in a sense “new” and “foreign” rather than an ancient relic weighing heavily on the shoulders of declining aristocracy. Even so we do indeed have something of that in the later revelations of previous owner Baron Tominaga and his particular grudges which, in this case, are if only partially rooted in wartime trauma, the mansion apparently also once home to an anti-aircraft depot the remains of which can be seen in the grounds.
The war may not be the corrupting force in play but it’s certainly a factor, especially the surprising accusation thrown at Dr. Munekata that he participated in wartime atrocity in being party to vivisection, a claim he does not dispute but defends in insisting his actions were justified in the name of science. The house has not so much called them, but each of the “guests” is in their own way morally compromised, Munekata not only a war criminal but a venal, lecherous old man hoping to get his hands on the house to open a sanatorium by fulfilling his quasi-incestuous desire for Yoshie. Yamashita, meanwhile, is not exactly pure hearted either, using what he knows about Munekata to blackmail him into standing down so he can become the director in his place and marry his wealthy girlfriend, Akiko (Keiko Yumi), who has also turned up to join in the haunted house fun. As far as sin goes, Yoshie is largely without it but perhaps pays for daring to own her sexuality, rejecting Munekata’s advances but apparently having made a habit of getting into bed with her comatose husband despite knowing of his many affairs which may be the reason for his punishment by the house. Only Kazuko remains pure and innocent save her one-sided attraction to Yamashita, the only one of the gang to show any kind of compassion towards the admittedly strange hunchback.
In keeping with the house, Tominaga and the hunchback are later revealed to be Christians, though in a gothic inversion they are also the source of the “evil” that infects the creepy old mansion once again positioning Christianity as a foreign corruption but also in this case punishing post-war moral failure. Sato conjures an atmosphere of pure gothic chill complete with oversize cobwebs, doors which open and close on their own, a crow infestation, and even a passing shinto priestess (Mitsue Suzuki) who just had to drop in because of the powerful emanations of evil echoing from the mansion but leaves his collection of extremely flawed humans very much at the mercy of their own demons as they desperately try to escape from the House of Terrors.
