Development
In an interview with The Japan Times, 3 Assassins English translator Sam Malissa described 3 Assassins as "Kōtarō Isaka calling out the thriller genre but [a]lso playing with the reader and the complicity of creating an illusion to invite people into the world of story and fabulations. In Japan, there’s quite a divide with books funneled to the pulp lane or the serious lane, but Isaka is riding that line between entertainment and more serious fiction, playing with those boundaries and pushing against that division. I’m always appreciative when artists straddle lanes or push boundaries like he does." Comparing the novel to Isaka's sequel novel Bullet Train (translated to English years ahead of its preceding novel), Malissa said that "3 Assassins goes deeper, so there’s more psychological exploration of the characters, which adds nuanced sophistication to the action."

Reception
The Japan Times praised 3 Assassins as a "rollicking good time", together with Bullet Train "showcas[ing] Isaka’s versatility as a writer and his skill as an entertainer, forging his own path as he merges literary fiction with high-octane fun." The Unseen Library lauded the novel as "another awesome read from Kotaro Isaka that takes readers on a wild and exciting journey to Japan’s outrageous underworld of assassins. Filled with quirky characters, surprising turns and intense action, this is a fantastic novel and you will swiftly get addicted to its entertaining and captivating story [and a] must read for fans of this legendary Japanese author", summarising it to be a "captivating and amusing overall story". with Hot Press complimenting it as a "Triple Tokyo Terminator Throw Down!", and The Irish Examiner expressing interest in the novel being adapted as a sequel to the 2022 Bullet Train film.

Contrasted to Bullet Train, The New York Times lauded "3 Assassins [a]s a sparser, sourer thriller, its slow pursuit distending across Tokyo and leaving plenty of time for dread", concluding that as a "surrealist fable disguised as a crime novel, “3 Assassins" feels like a fever dream that makes sense when you’re in it, but whose strange contours linger long after you wake up."

Manga adaptation
A manga adaptation drawn by Hiroto Ida was published from 2008 to 2010 on Kadokawa Shoten's Young Ace magazine, and later collected in three volumes.
