I've always loved geeking out over the little mechanics in 'Naruto', and this one’s straightforward once you separate awakening from activation. Amaterasu is a Mangekyō Sharingan technique, so you need to have the Mangekyō Sharingan itself unlocked first — that’s the awakening part. After that, actually using Amaterasu in battle requires you to activate the Mangekyō eye; Itachi visibly uses his Mangekyō when he casts Amaterasu, so the eye’s power has to be invoked for the black flames to appear.
That said, there are important caveats that I like to point out when talking with friends. When Itachi was reanimated (Edo Tensei), he could use Amaterasu without the usual physical drawbacks because his body wasn’t the same living physiology — Edo versions aren’t limited by chakra exhaustion or permanent eyesight loss in the same way, so his Mangekyō techniques were basically unlimited. Also remember that awakening the Mangekyō Sharingan (gaining the ability) is different from sustaining or suffering the consequences of repeated activation; Itachi’s original living self paid a huge price using those techniques repeatedly. So: yes, Amaterasu requires Mangekyō activation to cast, but the context (living vs reanimated, chakra reserves, protective counters like Susanoo) heavily affects how and how often Itachi could use it.

Man, whenever I watch the Itachi scenes in 'Naruto' I get that chill — his Amaterasu always felt like a rule-breaking force of nature. From the manga side (and the official databook notes that most fans cite), Amaterasu is presented pretty strictly: it’s a Mangekyō Sharingan technique that ignites black flames on the focal point the user chooses, and those flames will burn relentlessly until the target is incinerated, sealed, or the user puts them out. That gives the power a clear limitation structure — it isn’t limitless, it’s governed by use of the eye (line of sight, activation), by the user’s chakra and ocular stamina, and by very specific counters like sealing tools or other ocular/space–time techniques that can absorb or banish the flames.
In contrast, the anime sometimes treats Amaterasu more like a visual spectacle and less like a rigid mechanic. I’ve noticed anime-only scenes and some director choices that make the flames look more controllable, or show them being extinguished by non-canonical things (weather, sudden visual cuts, or generic water effects in fillers). The manga is tighter: you see clear instances where space–time ninjutsu like Kamui can take the flames away, and Susanoo’s legendary defenses (think Yata Mirror/Totsuka in lore) can block or seal attacks — those are canonical counters. Also, the strain on the user is emphasized more in manga panels and data notes: repeated Mangekyō use accelerates ocular deterioration, which is a real limiting factor for Itachi when he’s spamming Amaterasu.
My take? I prefer the manga’s rules for clarity — it makes fights feel like chess with concrete counters — but the anime’s flair adds drama. If you’re trying to decide “what actually limits Itachi’s Amaterasu,” go with the manga/databook baseline: it’s limited by activation (eye use, line of sight), chakra/ocular stamina, and specific counters (sealing, absorption by space–time techniques, or Susanoo-level defenses). If you watch the anime, just be ready to see visual variations and filler quibbles that sometimes bend those rules for spectacle.

Watching that scene in 'Naruto Shippuden' still gives me chills — Itachi's Amaterasu doesn't do anything mystical to Sasuke's eyes like swapping or permanently burning them out, but it definitely leaves a mark on the fight and on Sasuke physically. In canon, when Itachi fires Amaterasu during their final confrontation, the black flames lick at Sasuke's left eye area, scorching skin and lashes and making it look like the eye itself is on fire. The manga panels show smoke and the characteristic black flames around his eye, but crucially the Sharingan remains functional afterward. So what you're seeing is painful, visible burn damage to the eyelid/skin and a scary visual effect, not total ocular destruction.
From a mechanics perspective, Amaterasu is designed to burn relentlessly until its target is reduced to ash. Against a living person it can cause severe burns, and against chakra constructs like Susanoo it can do serious damage too — which is why its use against Sasuke during their clash mattered strategically. Sasuke at times manages to protect himself with his Susanoo and with sheer reflexes, so the flames don't simply erase his eyesight. Later on, Sasuke's real long-term eye problems come from prolonged Mangekyō Sharingan use, not that particular Amaterasu incident. In fact, Sasuke eventually receives Itachi's eyes to become an Eternal Mangekyō user, so any temporary damage from those flames was never the decisive factor in his ocular fate.
I like to think of that moment as a storytelling beat more than a surgical injury: Itachi's Amaterasu visually communicates the danger and obsession between the brothers. It scars the scene and Sasuke's face, gives him a raw look, and underlines how close Itachi came to destroying him — without actually making him blind on the spot. If you rewatch or reread the fight, look at how the panels frame the flames around Sasuke's eye versus his actual pupil; it's a neat reminder that in 'Naruto' injuries can be both symbolic and kinetic at the same time, and that the heavy duty ocular consequences came later from Mangekyō overuse and the transplant, not solely from that black flame.
