Samurai and their times loom large in the Japanese imagination, serving as sources of inspiration as well as symbols of Japanese culture and values of honor, loyalty and justice personified.

The adventures in Shotaro Ikenami’s 1970s serials “Kenkaku Shobai” (Swordsman’s business), however, tell a very different story.

A prolific author and playwright, Ikenami (1923-90) was not an artist unappreciated in his time. His works won multiple awards, including the prestigious Yoshikawa Eiji Literary Award and the Naoki Prize, and were adapted into films, television dramas and anime.

Said to be his greatest work, “Kenkaku Shobai” has received its first English translation, by Yui Kajita. Volume 1 was published in October as “The Samurai Detectives” by Penguin Books Ltd, which touts the stories as “Sherlock Holmes” crossed with recent TV hit “Shogun.”

We open on a seemingly ordinary day for young samurai Daijiro Akiyama, living alone at the dojo he set up with his father, Kohei, an exceptional warrior who has put down the sword in favor of lounging at home with his young lover.

“From now on,” Kohei says after helping establish the modest dojo upriver from central Edo, “you’ve got to do everything by yourself.”

This turns out to be truer than Daijiro intended, who has yet to enroll a student. As he goes about his tranquil, if solitary routine, a stranger approaches at night with a peculiar job offer: break the arms of a target without being told their identity, nor the reason behind the request. Should he accept, Daijiro would receive 50 gold ryo — in those days, enough to “easily live for five years on.”

Initially disapproving of Daijiro’s unpragmatic refusal, Kohei cannot resist investigating further, kicking off a series of mysteries — each self-contained but connected to the stranger’s offer, unveiling the corrupt underbelly of the Edo period (1603-1867).

Presenting adversaries from flawed to downright seedy, the novel looks to challenge traditional notions of samurai and their world for both our protagonists and the reader, keeping a refreshingly lighthearted tone throughout. Full credit to translator Kajita for retaining the uniquely Japanese humor and sense of adventure, as well as the diligent, yet never heavy-handed, anchoring of the historical terms and context.

Ikenami shines most of all in his awareness of the reader’s experience. Each twist is carefully revealed, undoubtedly honed with a playwright’s insight. At points, there are almost beats to hold for laughter, or the image of a stage fading to black as a chapter comes to a close. Similar is Ikenami’s intentional pacing, going from a leisurely rhythm before sharply swinging back into the action.

The father-son duo ultimately holds the story together as perfect foils for the other; young Daijiro with his principled, almost pious outlook versus Kohei’s more jaded, yet playful approach. It is easy to imagine the adventures of these two complementary figures capturing Japanese audiences from the decades of their original serialization to the adaptations long after.

The second volume, “The Samurai Detectives: The Killer on the Streets” came out in February, with “The Samurai Detectives: The Man in the Mist,” slated for August. As the translations arrive with renewed Western fascination in the subject matter, readers worldwide can finally travel back to see what’s afoot at Daijiro’s lonely little Asakusa dojo.
