Sakamoto Days is a high-octane Japanese action-comedy series written and illustrated by Yuto Suzuki. Originally debuting as a manga in Weekly Shōnen Jump in November 2020, the series has rapidly evolved into a global phenomenon. In 2025, the franchise reached a new milestone with a highly anticipated anime adaptation produced by TMS Entertainment and a live-action film slated for 2026. The story centers on Taro Sakamoto, a legendary hitman who retired for love, gained weight, and now runs a neighborhood convenience store while fending off relentless assassins without breaking his "no-kill" vow.

The Premise of Sakamoto Days

The narrative of Sakamoto Days thrives on a brilliant juxtaposition: the mundane life of a suburban family man versus the hyper-violent, stylized world of professional assassins. Taro Sakamoto was once the undisputed king of hitmen, feared by villains and revered by his peers. His life took a sharp turn when he fell in love with Aoi, a kind-hearted convenience store clerk. To marry her, Sakamoto accepted an ultimatum—he must leave the underworld behind and never kill again.

Fast forward a few years, and Sakamoto is a content, overweight father running "Sakamoto Stores" with his wife and daughter, Hana. However, the assassin world is not so easily escaped. As bounties are placed on his head and old rivals resurface, Sakamoto must protect his peaceful life. The catch? He must do so while adhering to his wife’s strict no-kill policy, leading to some of the most creative and non-lethal combat sequences in modern shonen history.

Who Is Taro Sakamoto?

Taro Sakamoto is the emotional and physical anchor of the series. Unlike the typical hot-blooded shonen protagonist, Sakamoto is stoic, quiet, and deeply devoted to his family. His character design is a deliberate subversion of the "legendary warrior" trope; he is depicted as a round, soft-spoken man who enjoys ramen and local community events.

However, beneath the exterior lies a body that remembers every ounce of its lethal training. In moments of extreme combat, Sakamoto utilizes a unique physiological trait: he can temporarily burn off his body fat through intense exertion, reverting to his slim, peak-athletic form from his hitman days. This transformation serves as a visual cue for fans that the "legend" has truly arrived on the battlefield. Even in his portly state, Sakamoto’s speed and reflex are unparalleled, often using ordinary store items—like pens, umbrellas, or bags of chips—as deadly weapons to incapacitate foes without ending their lives.

Meet the Sakamoto Store Employees and Allies

Sakamoto does not face the underworld alone. Over time, he builds a "found family" of eccentric individuals who help run the store and manage the influx of assassins.

Shin Asakura: The Telepathic Understudy

Shin is a former hitman who initially sought to bring Sakamoto back to the organization. He possesses the supernatural ability to read minds (clairvoyance), which initially made him an arrogant fighter. After being defeated and inspired by Sakamoto’s peaceful resolve, he becomes the store's first employee. Shin’s arc is one of growth, as he learns that reading minds is no substitute for raw skill and tactical intuition.

Lu Xiaotang: The Daughter of the Triad

Lu is the daughter of a deceased Chinese triad boss. She brings a "Drunken Fist" style of martial arts to the team, which is activated when she consumes even a small amount of alcohol (or alcohol-flavored sweets). Her character adds a layer of chaotic energy and international stakes to the neighborhood setting.

Heisuke Mashimo: The Reluctant Sniper

Heisuke is a quirky sniper with incredible aim but a soft heart. Accompanied by his loyal bird, Pi-suke, Heisuke represents the more specialized side of the assassin world. His inclusion allows the series to explore long-range tactical combat, diversifying the action beyond close-quarters brawls.

The World of Assassins and the JAA

The world-building in Sakamoto Days is centered around the Japanese Association of Assassins (JAA), a massive, corporate-like entity that governs the underworld. Within the JAA exists an elite tier of killers known as The Order. These individuals are the "special forces" of the assassin world, tasked with maintaining balance and eliminating high-threat targets.

The members of The Order are some of the most popular characters in the franchise due to their extreme power and distinct personalities:

  • Nagumo: A master of disguise and psychological warfare who was a former teammate of Sakamoto.
  • Shishiba: A cool-headed fighter who uses hammers as his primary weapon.
  • Osaragi: A gothic-lolita-styled assassin who wields a massive circular saw with terrifying grace.

The conflict often escalates when The Order becomes involved, as their presence signifies a shift from local store protection to high-stakes political maneuvers within the criminal underworld.

The Primary Antagonist: Slur and the New Order

As the series progresses, it introduces its primary antagonist, Kei Uzuki, also known as Slur. Slur is a mysterious figure with deep ties to Sakamoto’s past at the JAA training academy. Leading a group of radicalized assassins, Slur seeks to dismantle the JAA and create a world where killers are not bound by corporate rules.

The dynamic between Sakamoto and Slur is a highlight of the narrative. While Sakamoto fights for the status quo and his family’s safety, Slur represents a chaotic revolution. The ideological clash between Sakamoto’s "no-kill" philosophy and Slur’s "survival of the fittest" mentality creates a compelling tension that drives the later arcs of the manga and the second half of the 2025 anime.

Why the Action in Sakamoto Days Is Different

One cannot discuss Sakamoto Days without highlighting the sheer creativity of its action choreography. Yuto Suzuki, the series creator, has frequently cited his love for action cinema, specifically the works of Christopher Nolan and the John Wick franchise. This cinematic influence is palpable in every chapter and episode.

Cinematic Paneling and Flow

In the manga, Suzuki uses "impact frames" and dynamic perspective shifts that make the panels feel like they are in motion. He focuses heavily on the environment; a fight isn't just two people hitting each other; it’s a fight on a moving roller coaster, inside a crowded museum, or through the aisles of a convenience store. The use of everyday objects as weapons—a trope famously utilized by Jackie Chan—adds a layer of humor and ingenuity to the violence.

The Impact of TMS Entertainment

The anime adaptation by TMS Entertainment (known for Lupin III and Baki) has the difficult task of translating this fluid manga art into animation. The 2025 series has been praised for its use of 3D environmental modeling combined with traditional 2D character animation, allowing the camera to "spin" around the characters during complex fights, mimicking the "one-shot" long-take feel of modern action movies.

The 2025 Anime Release and Streaming Schedule

The Sakamoto Days anime is one of the pillars of the 2025 television season. Produced by TMS Entertainment and directed by Masaki Watanabe, the series was designed to be released in two "cours" (parts).

  • Cours 1 (January – March 2025): Focuses on the "Neighborhood" arcs, introducing the main cast and the initial attempts by low-level assassins to claim the bounty on Sakamoto.
  • Cours 2 (July – September 2025): Escalates the stakes, introducing more members of The Order and the beginning of the conflict with Slur.

Netflix secured the worldwide streaming rights for the series, ensuring it reached a global audience simultaneously with its Japanese broadcast. This move has been instrumental in the series' rapid rise in popularity among international viewers who may not have been familiar with the Weekly Shōnen Jump manga.

Manga Popularity and Sales Milestones

By August 2025, the Sakamoto Days manga reached over 15 million copies in circulation. This is a staggering achievement for a series that does not rely on traditional "power systems" like Ki, Nen, or Cursed Energy. Instead, its popularity stems from its relatable characters, top-tier art, and consistent pacing.

Weekly Shōnen Jump has positioned the series as one of its "new big three" alongside other modern hits. The manga’s "Final Battle" arc began in August 2025, signaling that the story is moving toward its climax, which has only increased interest in the anime as fans look to see the beginning of the journey once more.

What Is the Sakamoto Days Live-Action Film?

Reflecting the franchise's broad appeal, a live-action film adaptation was announced for a Q2 2026 release. Directed by Yūichi Fukuda, known for his work on the Gintama live-action movies, the film aims to capture the series' unique blend of slapstick humor and high-intensity action. Fans are particularly curious about how the production will handle Sakamoto’s physical transformations and the "superhuman" feats of the JAA assassins in a real-world setting.

Themes: Family, Vows, and Redemption

At its core, Sakamoto Days is a story about the weight of one's past and the struggle to change.

  • The Weight of a Vow: Sakamoto’s refusal to kill is more than just a plot device; it is a testament to his love for Aoi. It forces him to be smarter, faster, and more controlled than his opponents.
  • Found Family: The bond between Sakamoto, Shin, and Lu shows that family isn't just about blood; it's about the people who stand by you when the world comes hunting.
  • The Cost of Violence: Even as a comedy, the series occasionally touches on the hollow nature of the hitman lifestyle, contrasted with the warmth of the "boring" civilian life that Sakamoto cherishes.
