A mysterious childhood dream, a journey into Japanโs past and an encounter that could connect two lives across more than a century are at the heart of Rainy Day Serenade. The upcoming anime adaptation is beginning to take shape, and its latest announcement has given fans their first proper look at what to expect from the romantic time-slip story.
With its original manga already complete, the series is now moving towards its television debut. The latest reveal also brings together a new promotional visual, animated footage, cast announcements and several special events celebrating the franchise.
Rainy Day Serenade Anime Confirms April 2027 Broadcast
The television adaptation of Haruka Kawachiโs manga Rainy Day Serenade is officially scheduled to premiere in April 2027 in Japan.
The announcement was made on November 6, 2026, alongside the release of the animeโs first key visual and teaser promotional video (PV). These materials offer the first substantial glimpse of the upcoming production, introducing its central characters and the atmosphere surrounding their unusual connection.
The newly released key visual features Hina Katagiri and Takaaki Hongo standing back-to-back on a rainy street surrounded by Meiji-era architecture. Beneath them, the water reflects a garden and the figures of children, creating imagery connected to the story’s themes of childhood, memories and relationships that stretch across different periods.
The teaser PV takes things further by presenting the first animated footage from the series. It introduces the voices of both lead characters while offering an initial look at Hina’s mysterious dreams and the unexpected encounter that changes her life.
Although April 2027 is now confirmed as the broadcast window, the production team has not yet announced an exact Japanese premiere date.
Another Anime Adaptation Reaches the Screen
Anime adaptations are continuing to expand across different genres, including stories that move from manga pages into television productions. Fans looking for another recent adaptation announcement can explore our Otaku Vampire’s Love Bite anime report for details on its TV plans and story setup.
Yume Miyamoto and Takeo Otsuka Join Rainy Day Serenade Cast
The latest announcement has also confirmed the two main voice actors who will bring the story’s central characters to life.
Yume Miyamoto will voice Hina Katagiri, while Takeo Otsuka will portray Takaaki Hongo.
Hina is a straightforward, energetic high school student who has experienced the same mysterious dream since childhood. The recurring dream involves a boy and a garden, although its significance remains unclear to her.
Her ordinary life takes an unexpected turn when she suddenly finds herself transported to the Meiji era.
Takaaki, meanwhile, is the heir to the Hongo family and the young successor of Hongo Trading. He also carries memories of a girl he encountered during his childhood, creating an important connection between his past and the circumstances surrounding Hina.
The two actors have shared their thoughts about joining the adaptation.
Miyamoto expressed her happiness at portraying Hina, highlighting the story’s exploration of feelings that remain unchanged over time and connections between people that develop through misunderstandings. She also described Hina as someone who continues moving forward along her own path.
Otsuka reflected on his experience reading the original manga and participating in the recording process. He said the story brought out several emotions, including frustration, warmth, sadness, nostalgia and suspense.
He also explained that he wanted to portray Takaaki while remaining close to the carefully crafted words and emotions of the original work.

What Is Rainy Day Serenade About? Hina’s Journey to 1907 Explained
At the centre of Rainy Day Serenade is a mystery that begins with a recurring childhood dream.
Hina Katagiri repeatedly dreams about a mysterious boy and a garden on a rainy day. For years, these images remain part of her life without providing any clear explanation.
However, things change when she unexpectedly finds herself in a garden resembling the one from her dreams.
There, she encounters Takaaki Hongo, a well-dressed young man living during Japan’s Meiji era.
Hina soon discovers that she has travelled back to Meiji 40, corresponding to 1907, placing her more than a century away from the modern world she knows.
Her situation becomes even more complicated when she meets Hinako, a girl who looks remarkably similar to her.
Takaaki believes Hina is connected to the identity and circumstances of his own fiancรฉe. As a result, Hina becomes entangled in the lives of Takaaki and Hinako while trying to understand the reason behind her unexpected journey through time.
The story combines time travel, romance, family relationships and mystery. Its central premise explores how two people can become connected despite living in different periods, with Hina navigating the unfamiliar social environment of Meiji-era Japan.
The official anime website describes the series as a time-slip romance, placing the relationship between its central characters at the heart of the narrative.
Original Rainy Day Serenade Manga Is Complete With 14 Volumes
One important detail about the upcoming adaptation is that its source material has already reached its conclusion.
Haruka Kawachi began serializing Rainy Day Serenade in Kodansha’s Kiss magazine in November 2014. The manga continued for more than a decade before concluding in November 2025.
The completed series consists of 14 collected volumes, with the final volume released in Japan on February 13, 2026.
The anime adaptation was first announced on the same day as the release of the manga’s final volume in February 2026. At that stage, the production was confirmed for 2027, but the broadcast month, cast and principal staff had not been revealed.
The November 6 announcement has now provided those missing details, confirming the April 2027 broadcast window and introducing Miyamoto and Otsuka as the lead voice actors.
With the original manga complete, readers can already access the entire source story rather than following an ongoing serialization.
Rainy Day Serenade Spin-Off Manga Announced
The franchise is also preparing to expand beyond its completed main storyline.
A new spin-off titled Namidaame to Serenade Gaiden has been announced, with serialization scheduled to begin in Kodansha’s Kiss magazine.
The announcement comes after the main manga concluded in November 2025 and its 14th and final collected volume arrived in February 2026.
The spin-off forms part of a wider set of activities surrounding the television adaptation, which also includes an original-art exhibition and a special event featuring the manga’s creator and members of the anime production team.
Tokyo Exhibition to Showcase Original Rainy Day Serenade Artwork
Fans will have an opportunity to explore the manga’s artwork through a special exhibition in Tokyo.
The Rainy Day Serenade original-art exhibition is scheduled to run from November 25 to December 8, 2026, at the Aoyama Book Center.
Admission is scheduled to be free.
The exhibition will feature original manuscripts and artwork selected by Haruka Kawachi, alongside previously unreleased reproduced setting materials. Displays connected to the upcoming television anime will also be included.
Additionally, merchandise featuring newly drawn artwork by Kawachi to commemorate the anime adaptation is planned. Further details about the merchandise lineup will be announced separately.
The exhibition will also feature changes to some of its contents between the first and second halves of the event.
Haruka Kawachi to Attend December 6 Talk and Autograph Event
A special talk event and autograph session have also been announced as part of the exhibition programme.
Scheduled for December 6, 2026, the event will feature manga creator Haruka Kawachi, anime series-composition writer Yoko Yonaiyama and Kusao Takagi from Tezuka Productions.
The programme will include a discussion about the original manga and its anime production, followed by an autograph session with Kawachi.
The event will take place at Aoyama Book Center, with capacity limited to 80 people.
Tickets are scheduled to go on sale on November 14, 2026, at 12 noon Japan time, on a first-come, first-served basis. The announced price is 2,035 yen, including tax.
Official X Campaign Offers Signed Anime Key Visual Poster
The anime’s official X account has also launched a commemorative campaign following the announcement.
Fans who follow the official account and repost the designated promotional post can enter a drawing to win a B2-size key visual poster signed by both lead voice actors, Yume Miyamoto and Takeo Otsuka.
The campaign is scheduled to run until November 20, 2026, at 11:59 p.m. Japan time. The official announcement notes that the campaign period may be subject to change.
