Rainy Day Serenade Anime Unveils First Trailer and April 2027 Premiere

Rainy Day Serenade will begin airing in Japan in April 2027, with the anime's first teaser trailer and key visual released on November 6. The new footage introduces leads Hina Katagiri and Takaaki Hongo, voiced by Yume Miyamoto and Takeo Otsuka, and offers the first look at the time-slip romance in motion.

What the first teaser shows

The teaser centers on Hina's recurring dream of a garden and a boy she remembers from childhood. It then brings Hina and Takaaki together, previewing the meeting that connects their lives across different eras. Their character voices are heard for the first time in the animation, making the video the production's first proper introduction to both its visual atmosphere and central pair.

The first key visual places Hina and Takaaki against a Meiji-era streetscape. Beneath them, reflected water contains a garden and two young children, linking the present image to distant memories and the story's time-crossing premise. The visual was drawn by character designer Nobuteru Yuki.

The setup follows high school student Hina, who has repeatedly dreamed of meeting a boy in an unfamiliar garden on rainy days. She is suddenly transported to 1907, where she meets Takaaki, the heir to the Hongo family. He still carries memories of a girl he encountered when he was young, giving the pair's meeting a connection that predates Hina's arrival in his era.

Cast and production team

Miyamoto voices Hina, described as a straightforward, energetic student who keeps moving forward after being thrown into the Meiji period. Otsuka plays Takaaki, a young heir whose childhood memories remain important to him. The teaser provides an early sample of how their performances will frame the romance before the series starts next spring.

In her announcement comment, Miyamoto emphasized the story's enduring feelings and human connections, while describing Hina as someone who faces forward and advances on her own feet. Otsuka highlighted the source material's mixture of frustration, warmth, sadness, nostalgia, and suspense. He said his performance would stay close to Takaaki's carefully expressed words and the private emotions beneath them.

Tezuka Productions is producing the television anime. Takashi Kamei is directing, with Yoko Yonaiyama handling series composition and Yuki designing the characters. The announced team also includes art director Hiroshi Kato, color designer Kunio Tsujita, and director of photography Yoshie Ito.

The anime adapts Haruka Kawachi's manga, which ran in Kodansha's Kiss magazine and concluded after an 11-year serialization. Its story combines historical drama, romance, and time travel, with Hina's resemblance to another young woman in 1907 adding another mystery to her displacement. The manga has been collected in 14 volumes.

A specific broadcast date, Japanese network, and international streaming plan have not been announced. Before the April 2027 premiere, an exhibition celebrating the anime and the manga's new spin-off is scheduled at Aoyama Book Center in Tokyo from November 25 through December 8, with original art, reproduced production materials, and an anime display planned. A December 6 program at the same venue will pair Kawachi with Yonaiyama and Tezuka Productions representative Kusao Takagi for a special talk about the manga and anime, followed by a signing session. That event provides the next dated public checkpoint for the project.
