A murder has been committed in Tokyo, and Inspector Imanishi is assigned to unravel a complex mystery that spans different regions of Japan. What begins as a seemingly straightforward investigation turns into a meticulous journey of uncovering connections between seemingly unrelated people and events.
The book’s landscape descriptions are gorgeous, you can almost feel yourself walking through the rural Japanese scenery. But Inspector Imanishi? He’s not exactly the detective hero you’d expect.
Post-war Japan
To fully understand Inspector Imanishi Investigates, it helps to understand the world Seicho Matsumoto was writing from and for.
The novel was first published in Japan in 1961, set against a backdrop of a country still rebuilding its identity after the devastation of World War II. Post-war Japan was a society in profound transition. The American occupation had formally ended in 1952, but its cultural and political imprint remained deeply embedded. Traditional hierarchies were being questioned and economic recovery was underway.
Let’s talk about Imanishi. He is very much a product of this era. He’s low-ranking police detective, a civil servant, underpaid and methodical. He’s more of a passive investigator who seems to wait for clues to come to him rather than actively hunting them down. When Sherlock dazzles with intellectual fireworks and Hercule performs for the room, Imanishi simply persists. That patience is itself a cultural statement.
Sure, Imanishi travels here and there, but his detective skills feel lukewarm. What’s interesting is how he communicates (or doesn’t) with his colleagues. He’s a lone wolf, but not in the cool, strategic way – more like someone who’s just awkward about teamwork. It makes more sense when you understand that individual heroism wasn’t culturally celebrated the way it is in Western detective fiction.
The novel’s structure of moving across different regions of Japan also reflects about post-war identity. Matsumoto was documenting a country in the process of reconnecting its geography and its people after years of war had fractured both.
The Nouveau group, the avant-garde artistic circle at the centre of the mystery, represents the other side of this transition: the new Japan. It is Western-influenced, experimental, and in some ways morally unmoored. The tension between Imanishi’s old-world patience and the Nouveau group’s modern ambition gives the novel a social dimension that is more beyond a simple whodunit.
Imanishi’s treatment of his wife is another point of contention. Imanishi feels comfortable using his wife’s savings for investigation but worries about department expenses? Something doesn’t quite add up. Imanishi’s behaviour toward his wife is also rude, in my opinion. But Matsumoto’s portrayal of gender dynamics is very much a product of its time. Imanishi’s relationship with his wife reflects the social norms of 1960s Japan, which might feel uncomfortably dated to contemporary readers.
The book’s narrative structure is compelling, shifting perspectives between Imanishi and members of the Nouveau group. While this technique provides a broader view of the investigation, it occasionally diminishes the mystery’s tension. But the murder itself? Now that’s interesting. The modus operandi is something I’ve never encountered before, and isn’t that the beauty of fiction?
Despite its flaws, Inspector Imanishi Investigates offers a fascinating glimpse into Japanese detective fiction of the 1960s. It’s not perfect, but it’s definitely a unique read.
Rating: 4 muse points. Recommended for those who enjoy historical crime fiction with a side of cultural exploration.
