Honkaku is a century old Japanese tradition of clever and complex crime novels which are posed as a puzzle to the reader. The word means orthodox, and the genre was named so because the books followed the ten commandments of Fr. Knox rather strictly. Early Japanese honkaku writers were influenced by authors such as Edgar Allan Poe, Arthur Conan Doyle, Gaston Leroux, and John Dickson Carr, and paid homage to them by mentioning them by name in their books. During the 1970s the form was slowly supplanted by police procedurals. But it was revived in the 1980s as shin-honkaku, which retained the golden rule that the reader should know everything that the detective(s) find, but otherwise violated one or more of Fr. Knox’s ten commandments.

I spent the last month reading five Honkaku novels by five of the most well known Japanese practitioners. Most of the novels were set in the time period of their publication, except the one by Yokomizo, which was set in the late 1940s. The books follow the forms of classic criminal mystery stories. They are either locked room mysteries or, as in three of them, are set in an isolated house. Like in most western cosy mysteries, the detective is an amateur who manages to outperform the police. I found the mysteries to be pretty well constructed. Although I’ve seen or read many similar stories, even the older novels kept me guessing for a large part of the book. Even when I could guess who the murderer was, I could not get a neat answer which tied all the elements of the mystery together.
As a non-Japanese, I found the settings to be as interesting as the mystery in all these books. Some required detailed knowledge of the culture. For example, I had to stop once to look up the meaning of a six (or ten, or twelve) tatami room. It was fascinating to go from Shimada’s argument why no Japanese house has a genuinely locked room to Ayatsuji’s mystery which has a western style house with perfectly locked rooms. Starting from situations arising in post-war Japan, through social changes between early and late 80s, and into the more comfortable society of the pre-pandemic 21st century, there are elements of the puzzles which would be difficult to transport to a different society.
It was a pleasure to make the acquaintance of Yokomizo’s detective, Kosuke Kodaichi, who is a celebrity in his home country, and to meet again the very popular Manabu Yukawa (why doesn’t a mystery writer in the west ever think of a detective named Charles Einstein?) whom I first saw in “The Devotion of Suspect-X”. The Tattoo Muders was an interesting read because it kept introducing character after character who could be the detective (when he came on the scene eventually, it was clear that the rest were Watsons). I’m glad I decided to read these books. I’m looking forward to adding Japanese honkaku to my normal mix of reading.
