Death Note Age Rating: A Parent’s Guide From a Dad Who Watched It With His Kids

Death Note is one of those shows that never really goes away. It finished airing in 2007, and it still comes up whenever kids start talking about anime that is “actually good.” The tile is sitting right there on Netflix, the cover looks like a horror movie, and the plot is about a teenager who kills people with a notebook. No wonder parents look up the Death Note age rating before saying yes.

I first watched it on my own, years ago. This year I watched it again, this time with both kids and my wife, and both kids were hooked. So this guide comes from two viewings: one on my own, and one as a family.

The Short Answer

We rate Death Note 14+ to watch on their own. At 12 or 13 it can work if you watch it with them, which is how we watched it. You can see that rating next to every other show we have rated on our anime age ratings page.

What sets the number is the story, because the show has very little gore. The main character, Light, is a smart, popular high school student who decides he has the right to kill anyone he judges to be evil, and the show spends 37 episodes inside his head while he does it.

Our Finder lists three warnings for it: psychological horror, moral ambiguity, and death as the core theme.

If your kid is younger and wants a clever show with high stakes, Spy x Family is the easier yes. It is 12+ in our Anime Finder, my daughter watched it, and nobody in it is asking you to cheer for a serial killer. If they would rather read first, the manga is a good test of how they handle the story.

What the Labels Say

The labels mostly agree that this is a teen show. Where they disagree is how far into the teens.

Where you look	What it says
Netflix (US)	TV-14
Common Sense Media	15+
Common Sense Media parent reviews	13+
Common Sense Media kid reviews	12+
The 2017 Netflix live-action movie	TV-MA (a different, much rougher title)
Our rating	14+

I land a year below Common Sense Media because most of what they flag is about ideas, and ideas are easier to talk through with a 14-year-old than images are to unsee. The kid reviewers there say 12+, which tells you mostly that kids want to watch it. That gap between 12 and 15 is also the exact range where watching together makes the difference.

One thing to check before you press play: make sure it is the anime. Netflix also has a 2017 American live-action Death Note movie, and it is a very different thing, with real gore, a lot of swearing, and a TV-MA rating. Everything on this page is about the 37-episode anime series.

The Manga and the Netflix Movie

The anime follows the manga by Tsugumi Ohba and Takeshi Obata closely, 12 volumes in all. If your kid asks for the books, I would treat them the same as the show: same story, same age call. Takeshi Obata’s art is detailed and dark, and on the page you take the scary moments at your own pace, which some kids prefer.

The Black Edition above puts two volumes in each book, so six books cover the story. If they finish the first one and want the rest right away, the All-in-One Edition has all 12 volumes in a single, very large book.

The 2017 Netflix live-action movie is the one to steer around. It moves the story to Seattle, changes the characters, and turns up the blood and the swearing. Most fans of the anime would tell you to skip it.

What Is Actually in It

Violence

Less than you would think from a show called Death Note. Most of the deaths are heart attacks. Someone writes a name, a criminal on the other side of the world clutches their chest, and the camera moves on. There are a few shootings, a stabbing, a man hit by a truck, and Common Sense Media mentions torture, hostage-taking and an attempted sexual assault, but none of it lingers the way it does in Demon Slayer or Bleach.

Common Sense Media also notes that one character dies by suicide. If that is a topic you want to handle carefully in your house, it is worth knowing ahead of time.

The hero is the killer

This is the part that sets our rating.

Light starts with criminals, and in the first episode a kid can almost follow his logic. Within a few episodes he is killing the FBI agents sent to find him, and from there anyone who gets close is a target. The show never says he is right. It also never stops making him the smartest, coolest person in the room, and the cat-and-mouse with L, the strange genius detective hunting him, is written so you want to see who wins. Common Sense Media puts it bluntly: the main character “does not view his serial killing as wrong or evil.”

For a teenager who can hold two ideas at once (this is gripping, and this guy is a monster), that tension is the whole point of the show. A younger kid can miss the second half of that sentence. That is the conversation I would want to be in the room for.

Without spoiling anything, one of the two leads dies about two-thirds of the way through, and the story carries on for another twelve episodes without them. Kids who got attached to that character take it hard. A lot of fans also think the show is never quite as good after that point, so don’t be surprised if interest dips.

Scary stuff

Ryuk, the death god who drops the notebook, has a grinning, oversized face that Common Sense Media calls a “creepy image” that “may frighten some.” In practice he is the comic relief and spends half his screen time eating apples. The real tension is quieter: phones, surveillance cameras, a detective sitting with his knees up, and the slow sense that Light is about to be caught.

Romance, language and the rest

Romance is thin and not very romantic. Misa, a pop idol who becomes obsessed with Light, is mostly someone he uses. Common Sense Media rates the sexual content “a little”: innuendo, one shower scene where an outline shows, and a teen looking at a magazine of women in underwear. The language list in English runs from “damn” and “hell” up to “bastard” and an occasional f-word, depending on whether you watch dubbed or subtitled. Some characters smoke and drink wine.

Age by Age: 10, 12, and 14

At 10: not yet. The violence is mild, but a 10-year-old is exactly the viewer who might take Light at his word. If they want a smart show with a mystery feel, Mob Psycho 100 is 10+ in our Finder and has a hero who is kind, which is the opposite lesson.

At 12 and 13: together. Watched with a parent, a few episodes at a time, it is a great show to talk about, and the story gives you natural places to pause. Left alone with it, a 12-year-old gets the thrill without anyone pointing out what Light is turning into.

At 14: on their own. By 14 most kids can enjoy Light as a villain and understand that the show agrees. If they loved it, Steins;Gate is the natural next step: also 14+ in our Finder, also a clever, tense story, with far fewer bodies.

Watching It Together

We watched it as a family, my wife included. It is a show that rewards having a parent on the couch, because it keeps making Light look like he is winning, and it is easy to cheer for him without noticing what he has become.

The show hands you the questions, so there is no need to plan anything. Is Light still doing the right thing when he kills the agents? Would L’s methods be OK in real life? Who do you want to win, and why? A kid who can answer those has the show figured out.

Practical tip: it streams in the US on Netflix and Hulu (and a couple of other services as of October 2026, see our Finder). On Netflix, the anime and the 2017 movie both come up when you search, so pick the one with 37 episodes.

What’s Next

For more teen picks on the same service, our Netflix anime list by age puts Death Note next to Hunter x Hunter and Vinland Saga. If your kid is more into fights than mysteries, the shonen anime guide for parents and our Demon Slayer age rating cover the big action shows. Our anime watchlist by age is where I would start a younger kid, and everything else we have written about anime and manga lives on our anime and manga hub.

Start the first episode together. By the end of it you will know whether your kid is watching a thriller or rooting for Light.
