Born in Fukuoka in 1909, Seichō Matsumoto was one of Japan’s most acclaimed crime writers, publishing over thirty novels and several short stories during the course of his prolific career. His books, which often explored elements of human psychology and the broader social context of post-war Japanese life, made him popular with the country’s readers and critics alike. More recently, a handful of his books have been published in translation by Penguin Books, introducing Matsumoto’s work to a much wider audience.
I’ve already read and can highly recommend Matsumoto’s debut novel Tokyo Express (1958), an excellent howdunnit-style mystery, taking in elements of duplicity, intrigue and corruption, partly played out across Japan’s rail network, and Suspicion (1982) a tight, noirish novella about a suspicious death, which explores how public opinion and media reporting can influence the justice system. This brings me to the 1961 novel, Inspector Imanishi Investigates, one of Matsumoto’s best-loved novels, and an ideal read for Karen and Simon’s #1961Club. Ostensibly a complex, slow-burning police procedural, Inspector Imanishi Investigates also offers an intriguing insight into Japanese society in the early 1960s, a time when social inequalities and post-WW2 malaise characterised the social landscape. While the pace is more leisurely than in the other two Matsumoto novels I’ve read, there’s plenty for fans of his work to enjoy here – not least Inspector Imanishi himself, who proves to be a very likeable detective with a fondness for collecting bonsai trees and composting haikus.
From the opening pages, Matsumoto pitches us straight into the action when early one morning, the mutilated body of a man is found on the train tracks at Tokyo’s Katama Station. Naturally, the police are called in, and Inspector Imanishi quickly establishes himself as a leading player in the team. Despite some dogged detective work, the victim’s identity proves stubbornly hard to establish. A man resembling the victim was seen in conversation with another man, possibly the murderer, at a nearby bar the previous evening, but interviews with the bar staff identify just two potential clues – the name ‘Kameda’ and a distinctive accent native to Tohoku, the northeastern part of Japan’s Honshu region.
What follows is a lengthy, complex investigation as Inspector Imanishi and his younger colleague, Yoshimura, try to unravel the mystery surrounding the victim’s death, which an autopsy soon establishes as strangulation. The case takes the pair on a journey across Japan, exposing readers to a cross-section of Japanese society at the time, from modest workers in traditional rural communities to the more glamorous and murky lives of bar hostesses and their clients in the capital city.
‘…One case after another, the work keeps coming. But even though you’re assigned to something else, this kind of case stays on your mind. I’ve been a detective now for a long time, and I’ve been involved with three or four cases that were never solved. They’re old cases, but they’re always in a corner of my mind. Every now and then they pop up. It’s strange. I don’t remember anything about the cases that were solved, but I can recall clearly the faces of each of the victims of the unsolved cases. Well, now there’s one more to give me bad dreams.’ (pp. 57-58)
Central to the mystery are the Nouveau group, a collective of groundbreaking musicians, directors and critics eager to revolutionise various aspects of the creative arts, and possibly politics as well. One member, the composer, Waga Eiryo, is widely feted for his mission to ‘destroy the nature’ of conventional music’, attracting legions of adoring fans. His engagement to the daughter of a former cabinet minister – also an artist in her own right – adds another touch of prestige to Waga’s standing in the public eye. Also key to the group is Sekigawa, an influential critic who will stop at nothing to keep his affair with a vulnerable bar hostess under wraps. The deeper Imanishi delves, the more convinced he becomes of the Nouveau group’s involvement in the victim’s murder, but precisely how and why remain tantalisingly out of reach…
He left Club Bonheur feeling that he had been put in a difficult position. As he walked Ginza’s back streets, he realized his own contradictory thoughts. Neither Emiko nor Sekigawa was the object of his investigation. It was absurd for him to be pursuing them. Yet he could not figure out Emiko’s sudden move from his sister’s place. He connected this hurried move to the fact that she had found out he was a detective. The elaborate precautions she took in moving were suspicious. She appeared to be hiding something. But strange behaviour wasn’t reason enough for a detective to pursue her. (p. 196)
Part of the pleasure of this absorbing novel is spending time with Inspector Imanishi, who comes across as a courteous and meticulous man, slightly troubled by his advancing age and wasting police resources on an investigation that is proving remarkably challenging to crack. There are various false leads and loose ends along the way, many of which prove frustrating for the seasoned detective, but some lucky breaks prove fruitful, too. In fact, one criticism of the mystery part of the novel might be the numerous coincidences that crop up during the plot – probably too many to be true! However, I’m giving Matsumoto a pass on this, particularly given his interest in the murkier aspects of Japanese society.
The killer’s identity is rooted in the destruction Japan experienced during WW2, a time of great devastation for some and new opportunities for others. The stigmas associated with poverty, disease and homelessness are also significant here, prompting the murderer to disassociate himself from his origins at a formative age. These themes of shifting identities and reinvention are often part of the fabric of British mysteries set during wartime, but it’s interesting to see them in a parallel context here.
It had been very clever of him to establish his supposed parents at number 120, 2 Ebisu-cho, Naniwa Ward, in Osaka. This was an area where all the original family registers had been destroyed in an air raid. His school and the city had also been largely destroyed during the war. There were traces of his past, but nowhere was there concrete proof to establish his personal history, a history he had taken such pains to hide. (p. 322)
The solution to the crime, which includes a scientific element, is somewhat far-fetched, but as with many mysteries of this type, it’s the investigation itself and the insights into human nature that are more engaging than the resolution itself.
So, all in all, an absorbing, slow-burning mystery that offers readers many interesting insights into Japanese society at the time. There are signs of a country grappling with the balance between traditional societies with formal customs / hierarchies and progressive groups eager to push more radical thinking – a tension that provides plenty of opportunity for intriguing fiction, as Matsumoto discovered during his illustrious career.
