Based on Haruka Kawachi’s Manga
The anime adapts the manga written and illustrated by Haruka Kawachi. It was serialized in Kodansha’s josei manga magazine Kiss from November 2014 to November 2025, concluding with a total of 14 volumes.

A Mysterious Journey to Japan in 1907
Rainy Day Serenade follows Hina, a young woman who frequently dreams about her childhood self playing with a mysterious boy in an unfamiliar garden whenever it rains.
Her dreams take an unexpected turn when she eventually discovers the very same place in reality. There, she encounters a young man named Takaaki, who mistakes her for his fiancée, Hinako.
Takaaki then takes Hina to what he believes is her home, where she comes face-to-face with someone who looks exactly like her. It is only then that Hina realizes something is terribly unusual: she has somehow arrived in Japan in 1907, rather than the Tokyo she originally came from.
With its blend of romance, mystery, and historical elements, Rainy Day Serenade promises an intriguing story centered on identity and an unexpected journey through time. More details about the anime are expected to emerge ahead of its April 2027 premiere.
