Hirayasumi, the forthcoming anime adaptation of Shinzo Keigo’s manga, has offered its clearest look yet at the series before its planned January 2027 debut on Japan’s NHK General TV. A new teaser, a key visual and the principal voice cast place the spotlight on a story built around ordinary routines, an inherited home and relationships that carry more weight than they initially seem to.

For now, the confirmed broadcast destination is NHK General TV in Japan. International streaming plans have not been disclosed, so viewers outside Japan will need to wait for further distribution news. Additional coverage of the new footage and cast likewise points to the production’s January 2027 target rather than a confirmed worldwide platform.

A quiet premise with room for complicated feelings

The teaser follows Hiroto, a 29-year-old part-time worker, in the Asagaya neighborhood as he moves through the cadence of everyday life. That setup is intentionally modest: this is not a series being framed around a tournament, a supernatural crisis or an escalating mystery. Its dramatic engine is human connection, including Hiroto’s bond with his elderly neighbor, whom he calls Granny, and the disruption and possibility created when his cousin Natsumi comes to Tokyo to attend art school.

The newly revealed key visual gathers the core group in front of the one-story Asagaya house Hiroto inherited from Granny. Hiroto and Natsumi are joined by Hideki, Hiroto’s closest friend; Akari, Natsumi’s university classmate; and Yomogi, a local real-estate agent. The house is more than a backdrop in the information shared so far. It is the physical point around which relatives, old friends, neighbors and new aspirations can meet.

That emphasis helps explain the title’s appeal as a slice-of-life premise. Slice of life is a term commonly used for fiction that gives sustained attention to daily routines and interpersonal details rather than structuring every episode around a large external objective. It does not mean the absence of conflict. In Hirayasumi, the announced character descriptions point toward quiet frictions: different ages, career uncertainty, loneliness, creative ambition and the private burdens that kind people may still carry.

Hiroto is presented as relaxed and unpretentious, while Natsumi is an 18-year-old newcomer from Yamagata who is more reserved and harbors a private ambition to become a manga artist. Their contrasting temperaments lead them to clash. Granny, whose full name is Wada Hanae, is 83 and formerly served school lunches; after meeting Hiroto by chance, she begins having dinner with him twice a week. Those details suggest that meals, home life and small repeated encounters will be important spaces for the show’s drama.

The principal cast

Yuma Uchida will voice Hiroto. His past roles include Megumi Fushiguro in Jujutsu Kaisen, Ash Lynx in Banana Fish and Reo Mikage in Blue Lock. Uchida has described Hirayasumi as a work where drama emerges from commonplace moments, and said he wants to portray Hiroto without losing the character’s laid-back, straightforward quality.

Mayu Takahashi plays Natsumi. Takahashi previously placed second in the Kimi Koe Project, an initiative created to identify and train new voice actors, and has a prior credit on The Legendary Hero Is Dead!. Her comments underline a personal affinity with Natsumi after reading the manga. That connection is notable given Natsumi’s position in the story: she is beginning a new life in the capital while keeping her artistic dream largely to herself, a starting point with plenty of scope for guardedness and uncertainty.

Rikako Aikawa voices Hanae, or Granny. Aikawa’s long list of roles includes Squirtle in the Pokémon franchise, Oxnard in Hamtaro and Ishishi in the Kaiketsu Zorori series. She has characterized the ensemble as fundamentally kind, while stressing that each character also has pain and worries beneath the surface. Her description captures what appears to be the adaptation’s central emotional promise: not broad melodrama, but gradually accumulating feeling.

“All of the characters are very kind. And yet, deep inside, they carry pain and worries of their own,” Aikawa said of the story’s emotional texture.

The remaining characters visible in the new key art—Hideki, Akari and Yomogi—establish the social circle around Hiroto and Natsumi, though casting details for them were not included in the material released alongside the teaser. It is worth separating what has been confirmed from what viewers may infer: the visual establishes their importance to the setting, but it does not define each person’s eventual narrative role.

The creative team behind the adaptation

Production +h. is animating Hirayasumi. The studio’s previous work includes The Orbital Children and Dead Dead Demons Dededede Destruction. Kei Suezawa is directing, handling series composition and writing the scripts. In anime production, series composition generally refers to the planning and coordination of a show’s overall story structure, including how material is arranged across episodes. Having the director also perform that role can provide a direct line between episode-level storytelling decisions and the series’ wider shape.

Naoyuki Asano is the character designer, Mika Nishimura is art director and Kaori Sawada is composing the music. Character design is especially consequential for a manga adaptation whose appeal rests on people feeling recognizable and lived-in rather than simply spectacular. The role involves translating original character artwork into designs that can be animated consistently. The art director oversees the visual approach to environments and backgrounds, an important responsibility for a series rooted in a specific neighborhood and a single-story home. Sawada’s music will have the task of supporting intimate scenes without overpowering the restrained register the cast has described.

Suezawa’s previous credits include Fate/Grand Order: Camelot – Wandering; Agateram and FLCL Progressive. Asano has worked on Urusei Yatsura and Keep Your Hands Off Eizouken!, while Nishimura’s work includes Typhoon Noruda. Sawada’s credits include What Did You Eat Yesterday? and When Spring Comes. These credits establish the announced team, but they should not be treated as a guarantee that Hirayasumi will resemble any one earlier project. The adaptation’s own tone will depend on how its staff shape Shinzo’s characters, places and pacing for television.

Why the manga arrives with a strong foundation

Shinzo began serializing Hirayasumi in Shogakukan’s Weekly Big Comic Spirits in 2021. The manga currently spans 10 volumes and has more than 1.7 million copies in print worldwide. It has also received major recognition, including the best serial comic prize at Lucca Comics & Games 2024 and the 71st Shogakukan Manga Award.

Those facts give the anime a substantial foundation, but they do not prescribe a one-to-one adaptation. Manga and television animation organize time differently. A manga can allow readers to linger on a panel, revisit a page or control the pace of a conversation. Animation instead sets the tempo through performances, editing, sound, background atmosphere and music. For a work centered on everyday exchanges, these choices can matter as much as any plot point. A pause at the dinner table or a walk through Asagaya has to feel purposeful without being rushed into a more conventionally event-driven rhythm.

Shinzo’s wider career also provides useful context. He debuted in 2008 with Nankin. His 2016 work Moriyamachu Driving School later became a feature film, while Tokyo Alien Bros. received a live-action adaptation in 2018. An autobiographical one-shot about the creator’s recovery from lymphoma, made during the COVID-19 pandemic, also served as an inspiration for Hirayasumi. That is meaningful background to the series’ emphasis on care, emotional strain and the value of uneventful time, though it does not turn the manga or anime into a direct autobiography.

What has been confirmed—and what has not

  • Confirmed: Hirayasumi is scheduled to premiere in January 2027 on NHK General TV in Japan.
  • Confirmed: Production +h. is producing the animation, with Kei Suezawa directing, overseeing series composition and writing scripts.
  • Confirmed: Yuma Uchida plays Hiroto, Mayu Takahashi plays Natsumi and Rikako Aikawa plays Hanae.
  • Confirmed: The new teaser centers on Hiroto’s daily life, his relationship with Granny and Natsumi’s arrival to study art in Tokyo.
  • Not yet announced: An international streaming service or overseas release plan.
  • Not yet detailed: A specific episode count, full cast list or broader release schedule beyond the January 2027 Japanese premiere window.

For prospective viewers, the practical takeaway is simple: Hirayasumi is one to keep on the radar if character-led, grounded anime is appealing, but there is no confirmed way to watch it internationally yet. The teaser and key art establish a production focused on Hiroto, Natsumi, Granny and the small community around the Asagaya house. The next substantial update will likely need to clarify distribution and provide a more complete picture of how that quiet, emotionally layered world will unfold on screen.
