The Hirayasumi anime adaptation has officially expanded its voice roster with five new cast members. This announcement follows the world premiere of the first episode earlier this month in New York, signaling a steady production pace for the highly anticipated slice-of-life series.
Scheduled for a January 2027 premiere, the project adapts Keigo Shinzo's award-winning manga about the quiet, interconnected lives of a carefree part-timer and his art student cousin. The latest casting update focuses on the supporting characters who round out the show's domestic and professional circles.
What We Know
The new additions include veteran and rising voice talent. Daisuke Namikawa joins the cast as Hideki Noguchi, a high school friend of the protagonist who works at a furniture store. Yoko Hikasa will voice Yomogi Tachibana, a career-oriented woman dealing with urban burnout.
Other additions include Yume Miyamoto as Akari Yokoyama, Natsumi's first university friend, and Yuichiro Umehara as Ryo Ishikawa, a novelist in a slump. Yuko Naito, a Japanese television announcer, will serve as the narrator. These actors join the previously announced main trio: Yuma Uchida as Hiroto Ikuta, Mayu Takahashi as Natsumi Kobayashi, and Rikako Aikawa as Hanae Wada.
The production is handled by Studio Production +h., with Kei Suezawa directing and managing series composition. Naoyuki Asano is providing character designs, while Kaori Sawada composes the music and Mika Nishimura serves as the art director.
Why It Matters
Hirayasumi is not a typical high-energy seasonal lead; it is a critically acclaimed "iyashikei" (healing) story that has earned significant hardware, including the 71st Shogakukan Manga Award in 2026. The casting of heavy hitters like Namikawa and Hikasa suggests that Production +h. is treating the supporting cast with the same weight as the leads, ensuring the show's grounded atmosphere remains compelling.
The timing of these announcements is also notable. The manga is confirmed to end in two chapters as of October 2026. For fans of the low-stakes, high-emotion subgenre, the involvement of VIZ Media and ShoPro as production partners indicates a serious push for international visibility beyond the Japanese broadcast.
Where to Watch or Read
In Japan, Hirayasumi will broadcast on NHK General TV starting in January 2027. While VIZ Media holds the international license, specific streaming platforms have not yet been confirmed for the Western release.
For those who want to catch up on the story before the anime begins, the original manga is serialized in Weekly Big Comic Spirits. Additionally, a 20-episode live-action drama aired in late 2025 and is currently available to stream on Prime Video as of October 2026.
What Happens Next
The anime is set for the Winter 2027 season with a firm January start date. While the live-action adaptation ran for 20 episodes, the official episode count for the anime has not been announced. Fans should expect more promotional trailers and specific international streaming details as the premiere window approaches.
