This is the first named jutsu in the entire manga — it's on the stolen scroll Naruto reads on page 25 of Chapter 1, before the reader has seen a single fight. VIZ's translation choice at that exact moment already tips its hand: the scroll entry is rendered "MULTIPLE DOPPEL-GANGERS," using "doppelganger" (a German loanword for an uncanny double) rather than the more literal "shadow clone" that the anime dub and most fan translations settled on. That word choice sticks for the entire VIZ print run — every other English adaptation of Naruto calls this move "Shadow Clone," but the manga never does.
The corpus also shows VIZ's rendering visibly evolving in real time across early volumes. Chapter 1's solo cast (Vol. 1 p.76, Naruto's first-ever use in a fight) reads simply "ART OF THE DOPPEL-GANGER!!!!" — no "shadow" at all, treating it as a variant of the basic Clone Jutsu. By Vol. 4, fighting on the bridge in the Land of Waves, the wording has already shifted to "ART OF THE SHADOW DOPPLE-GANGER!!" (note the transitional misspelling), and from there "shadow" sticks for the rest of the series — through Vol. 70's late-series "ART OF SHADOW DOPPELGANGERS!!!" (now plural, no "THE"). For the mass-clone variant specifically, VIZ occasionally does something it almost never does elsewhere in the manga: it prints the Japanese romaji directly in the dialogue, "TAJU KAGE BUNSHIN NO JUTSU!", immediately followed by the English gloss "ART OF THE MULTIPLE SHADOW DOPPEL-GANGERS!!!" (Vol. 15 p.142; Vol. 20 p.77 spells it "TAJÛ" with a circumflex). No other jutsu in this dictionary gets that double treatment on a recurring basis.
The Vol. 1 p.143 panel used for this entry's crop is itself a flashback callback within Chapter 1's own timeline — Sakura and Sasuke, watching Naruto casually summon eight solid bodies against Zabuza and Haku's ambush, are told outright by the narration that this is "the technique he used to defeat Mizuki," tying the Land of Waves arc directly back to the graduation-exam climax only chapters earlier. Kage Bunshin is arguably the single technique the corpus references most often of any jutsu in the manga (182 solo-clone mentions plus 18 explicit "taju"/multi mentions, 200 total) — a reasonable proxy for how load-bearing it is to Naruto's entire fighting style, from reconnaissance and decoy work to raw numbers advantage, for all 72 volumes.
