The upcoming Spring 2026 anime season just got more exciting as Kujima: Why Sing, When You Can Warble? continues to build anticipation with a fresh wave of casting announcements. According to Anime News Network, the television anime adaptation of Akira Konno’s beloved manga revealed three additional cast members and an eye-catching new visual on January 30, 2026, bringing fans one step closer to the series’ April 2026 premiere.

This latest update adds crucial family members to the voice cast, enriching what promises to be a heartwarming and comedic exploration of family dynamics with a supernatural twist. The newly announced cast members include the talented Yōhei Azakami as Suguru Kōda, Ryōko Shiraishi as Miyoshi Kōda, and Hirofumi Nojima as Masaomi Kōda. These actors join the previously revealed leads, Yuria Kōzuki voicing the mysterious titular creature Kujima, and Ayumu Murase bringing life to first-year middle school student Arata Kōda.
A Peculiar Bird Brings Fresh Air to a Tense Household
For those unfamiliar with the source material, Kujima: Why Sing, When You Can Warble? (known in Japanese as Kujima Utaeba Ie Hororo) is described as a “bird(?) home comedy” that centers on an unexpected houseguest who transforms a family’s atmosphere. The story begins in autumn when Arata Kōda, a first-year middle school student, encounters a mysterious bird-looking creature named Kujima. Hungry and craving authentic Japanese food, Kujima ends up staying with the Kōda family at their home—a household where tension runs high due to Arata’s older brother having failed his college entrance exams.
What makes this premise particularly compelling is how it uses the fantastical element of Kujima’s presence as a catalyst for addressing very real family stresses. The pressure surrounding entrance exams is a deeply relatable theme in Japanese culture, and the manga has been praised for handling this sensitive topic with warmth and humor. Kujima lives with the Kōda family throughout the winter months until warm spring arrives, presumably bringing change and growth to everyone involved.
An Award-Nominated Manga Gets the Anime Treatment
Akira Konno’s original manga enjoyed a successful three-year run in Shogakukan’s Monthly Shonen Sunday magazine, serializing from September 2021 to April 2024. The series concluded with five compiled tankōbon volumes, with the first released in April 2022 and the final volume published in May 2024. Despite its relatively compact length, the manga made significant waves in the industry, earning a nomination in the print category of the eighth “Next Manga Awards” (Tsugi ni Kuru Manga Taishō) in 2022.
Additionally, the series was included in the top 20 list of manga for male readers in the 2023 edition of Takarajimasha’s prestigious Kono Manga ga Sugoi! (This Manga Is Amazing!) guidebook. These accolades speak to the manga’s unique appeal and quality storytelling, suggesting that the anime adaptation has strong source material to work with. The recognition also indicates that Kujima resonated with both readers and industry professionals, building a solid foundation of anticipation for its animated debut.
Studio Hibari Brings the Kōda Family to Life
The anime production is being handled by Studio Hibari, a veteran animation studio founded in 1979 that has built a reputation for quality work across various genres. Leading the directorial team is Noriyuki Nomata, who brings extensive experience as an episode director on popular series including Assassination Classroom, Carole & Tuesday, and The Ancient Magus’ Bride. Nomata is working alongside series director Shinichiro Kimura, known for his work on Hand Maid May, creating a collaborative leadership structure for the project.
The creative team also includes Yasunori Yamada handling series composition, ensuring narrative cohesion across episodes, and Sakurako Mitsuhashi designing the characters for animation. Rounding out the core staff is composer Manami Kakudō, who will be crafting the musical landscape that helps set the tone for this unique home comedy. This combination of experienced professionals suggests a production team well-equipped to capture both the humor and heartfelt moments that made the manga special.
Meet the Voice Cast Behind the Kōda Family
The voice cast assembled for Kujima: Why Sing, When You Can Warble? brings together both established talent and rising stars. Yuria Kōzuki takes on the challenging role of Kujima, the enigmatic creature whose presence drives the story. Voicing the protagonist Arata Kōda is Ayumu Murase, a Seiyu Award-winning voice actor particularly known for his ability to portray younger characters with his distinctive vocal range. Murase’s notable roles include Hinata Shoyo in Haikyu!! and has become one of the industry’s most recognizable voices for energetic young protagonists.
The newly announced cast members fill out the Kōda family roster. Yōhei Azakami, who voices Suguru Kōda (the older brother dealing with exam pressure), has gained significant recognition for roles like Guel Jeturk in Mobile Suit Gundam: The Witch from Mercury and the title character in Ron Kamonohashi’s Forbidden Deductions. His ability to convey complex emotional states makes him an excellent choice for a character navigating the stress of academic expectations.
Ryōko Shiraishi brings her extensive experience to the role of Miyoshi Kōda, while Hirofumi Nojima voices Masaomi Kōda. Both are veteran voice actors with decades of experience and diverse portfolios, adding depth and credibility to the family dynamic that forms the heart of the series.
Where and When to Watch
Anime fans won’t have to wait much longer to experience this unique story. Kujima: Why Sing, When You Can Warble? is scheduled to premiere in April 2026 on several Japanese broadcast networks, including Tokyo MX, MBS, BS-TBS, and AT-X. For domestic Japanese audiences, the series will also stream on U-NEXT and Anime Hōdai platforms.
International viewers will be able to enjoy the series thanks to Crunchyroll, which has secured streaming rights and will simulcast the anime as it airs in Japan. This simultaneous release strategy ensures that global audiences can experience the series alongside Japanese viewers, fostering a unified fan community from the very beginning. Crunchyroll’s involvement also means the series will likely receive professional English subtitles and potentially an English dub down the line, making it accessible to the widest possible audience.
Why This Anime Stands Out in Spring 2026
In an anime landscape often dominated by action-packed shonen series and isekai adventures, Kujima: Why Sing, When You Can Warble? offers something refreshingly different. The series promises to deliver a slice-of-life comedy with supernatural elements that explores genuine family dynamics and the pressures faced by students in contemporary Japan. The premise of a mysterious creature inadvertently helping a family work through their tensions has echoes of beloved classics like Barakamon and Usagi Drop, which similarly used unconventional circumstances to explore themes of personal growth and family bonds.
The manga’s critical recognition suggests that Akira Konno crafted something special—a story that balances humor with genuine emotional resonance. The “bird(?)” designation in the series description hints at the ambiguous nature of Kujima itself, adding an element of mystery to what might otherwise be a straightforward family comedy. This ambiguity allows for creative storytelling possibilities and keeps audiences guessing about Kujima’s true nature and origins.
Moreover, the timing of the series’ release in spring—traditionally associated with new beginnings in Japanese culture, as it marks the start of the school year—aligns perfectly with the story’s themes of change and renewal within the Kōda household. The narrative arc that takes Kujima from autumn through winter and into spring mirrors the natural cycle of seasons and suggests a story about weathering difficult times together as a family.
Building Anticipation with Strategic Reveals
The production committee behind Kujima: Why Sing, When You Can Warble? has been steadily building anticipation through carefully timed announcements. The initial anime announcement came in May 2024, following the manga’s conclusion. The first major reveal of staff, main cast, and a teaser video occurred in November 2025, establishing the core production details. Now, with this January 2026 update adding family members to the cast and unveiling a new key visual, the marketing campaign is clearly designed to maintain momentum leading into the April premiere.
This measured approach to information release keeps the series in the conversation without overwhelming potential viewers. Each announcement provides new details that flesh out our understanding of how the anime will take shape, while the new visual gives fans something concrete to analyze and discuss. The strategy also allows the production team to showcase different aspects of the series—first the premise and leads, now the supporting family members who will be crucial to the story’s emotional core.
Final Thoughts
As the Spring 2026 anime season approaches, Kujima: Why Sing, When You Can Warble? is shaping up to be one of the season’s most intriguing offerings. With its award-nominated source material, experienced production team at Studio Hibari, and talented voice cast led by Yuria Kōzuki and Ayumu Murase, the series has all the ingredients for success. The latest casting announcements for the Kōda family members—Yōhei Azakami, Ryōko Shiraishi, and Hirofumi Nojima—add further depth to what promises to be a heartwarming exploration of family, pressure, and the unexpected ways help can arrive.
For fans of slice-of-life anime with a twist, thoughtful family dramas, or simply those looking for something different from the typical seasonal offerings, Kujima: Why Sing, When You Can Warble? deserves a spot on your watchlist. With Crunchyroll handling international distribution, accessing this unique series will be easy for viewers worldwide. As we count down the weeks until April 2026, the mystery of what exactly Kujima is—and how this peculiar creature will transform the Kōda family—continues to intrigue and captivate.
