If you scroll through Shonen Jump right now, you’re going to see a lot of sorcerers, demons, and pirates. It’s the standard fare. But buried in that lineup is a series that started quietly, looked like a goofy gag manga, and then proceeded to deliver some of the most insane, high-octane action choreography I have ever seen in the medium.
I’m talking about Sakamoto Days.
I’ll be honest with you: when I first saw volume 1, I hesitated. The cover features a chubby, bespectacled guy with a mustache looking completely zoned out. I thought, “Okay, is this just The Way of the Househusband 2.0? A slice-of-life comedy about a retired tough guy?” I was expecting a few giggles and maybe a heartwarming lesson about groceries.
I picked it up on a whim one rainy Tuesday, thinking I’d read a chapter or two before bed.
Big mistake.
Three hours later, I was forty chapters deep, my jaw was on the floor, and I was texting every anime fan I know screaming, “ARE YOU READING THIS?!”
Here is the vibe check: Imagine John Wick gained 50 pounds, decided to open a 7-Eleven, and refused to ever kill anyone again—but the entire assassin underworld is still trying to kill him. It is equal parts slapstick hilarity and adrenaline-pumping violence. It’s cozy, it’s chaotic, and it is absolute peak fiction.
The Premise: The Chubby Shopkeeper with a Dark Past
Let’s set the stage, spoiler-free.
Meet Taro Sakamoto. He used to be the “Greatest Hitman of All Time.” He was the boogeyman that other assassins told stories about. He was untouchable, unstoppable, and undeniably cool.
Then, the impossible happened: He fell in love.
He met a woman, fell head over heels, and made a promise to her: He would leave the underworld, get married, have a kid, and never kill again. Fast forward a few years, and the legendary hitman is now a family man. He’s gained quite a bit of “happy weight,” he loves his wife and daughter more than life itself, and he runs a humble neighborhood convenience store.
But you can’t just walk away from the assassin world.
Old rivals, new hitmen, and a mysterious organization known as “The Order” keep showing up to disrupt his peaceful life. Sakamoto has to protect his family and his store without breaking his no-killing rule. This forces him to get creative. Instead of shooting people, he’s knocking them unconscious with cough drops, deflecting bullets with price scanners, and using raw beef as a weapon.
He’s joined by Shin, a young clairvoyant assassin who can read minds (and acts as the frantic “straight man” to Sakamoto’s stoic absurdity), and Lu, a triad heiress with a very specific fighting style involving alcohol. Together, they are the strangest, most dangerous convenience store staff in Japan.
Why It Hits Different: A Masterclass in Visual Storytelling
I read a ton of manga—thousands of chapters a year. I don’t say this lightly: Yuto Suzuki (the author) is currently the best action director in manga. Period.
1. The Action Choreography is Insane
Most action manga rely on “Beam Struggles” or big explosions. Sakamoto Days relies on movement.
Suzuki has an incredible understanding of spatial awareness. When a fight breaks out in a narrow train car, a crowded department store, or a falling elevator, the environment isn’t just a background; it’s a weapon. Characters bounce off walls, slide under tables, and use reflections in mirrors to aim shots.
There is a fluidity to the panels that makes your brain fill in the gaps effortlessly. You aren’t just looking at still images; you are watching a movie play out in your head. The impact frames—the moments where a punch connects—are visceral. You feel the weight of the hits. One minute Sakamoto is scanning groceries, and the next, the panel layout shatters as he suplexes a guy through a display shelf. It is kinetic art at its finest.
2. The “Rule of Cool”
While Sakamoto is the heart of the series, the side characters bring the heat. Specifically, The Order.
The Order is the governing body of the assassin world, and every single member is designed with dripping swagger. You have Shishiba, the calm, hammer-wielding pro; Osaragi, a gothic-lolita executioner who is terrifyingly ditzy; and others I won’t spoil.
Whenever The Order shows up, the genre shifts from “Action-Comedy” to “High-Stakes Thriller.” The tension spikes. Suzuki knows exactly how to balance the goofy moments with moments of sheer terror. One page you’re laughing at Shin trying to read Sakamoto’s mind (and only seeing thoughts about ramen), and the next page, a villain walks in and the air in the room changes.
3. It’s Surprisingly Wholesome
Despite the bullets flying and the knives slashing, this manga has a massive heart.
Sakamoto isn’t fighting for glory or money. He’s fighting to protect his mundane happiness. He wants to finish the fight quickly so he can get home for dinner. That motivation is so relatable. The “Found Family” dynamic between Sakamoto, his wife Aoi, Shin, and Lu is genuinely touching. You care about these idiots. You want them to succeed not just because they are cool, but because they are a family.
I found myself grinning like an idiot during the downtime chapters just as much as I was hyping up the battle chapters.
How & Where to Read (Don’t Be a Pirate!)
If I’ve convinced you (and I really hope I have), you need to read this the right way. Supporting the official release ensures we keep getting this quality content and pushes us closer to an anime adaptation.
Where to read:
-
Manga Plus (Highly Recommended): This is the official app/site by Shueisha. You can usually read the first three and the latest three chapters for free. If you download the app, they often have a “First Read Free” model where you can read the entire series once without paying a dime. It’s the best way to catch up.
-
The Shonen Jump App / Viz Media: For $2.99 a month, you get access to the entire vault. The image quality is crisp, the translations are official, and the double-page spreads look gorgeous on a tablet.
-
Physical Volumes: If you are a collector, the physical volumes are stunning. The cover art usually features creative, fisheye-lens perspectives or graffiti-style coloring that looks great on a shelf.
A Quick Note for Newbies:
If this is your first manga, remember: Read from Right to Left. Start at the top right corner, move left, then go down to the next row on the right. It feels weird for about 5 minutes, and then it becomes second nature.
Final Verdict: The S-Tier Experience
So, who is Sakamoto Days for?
-
If you liked the humor of One Punch Man but wanted more grounded hand-to-hand combat…
-
If you loved the “retired badass” trope of John Wick or The Equalizer…
-
If you just want to see a guy kill a hitman with a ballpoint pen while worrying about his cholesterol…
This is for you.
It is a rare series that manages to be funny, heartwarming, and utterly badass all at the same time without suffering from tonal whiplash. It respects your time, the pacing is lightning fast, and the art just gets better with every single volume.
We are witnessing a future classic in the making. Do not wait for the anime (which is coming, by the way, and will likely break the internet). Read it now so you can be one of the cool kids who says, “I was here before it was mainstream.”
