Rainy Day Serenade is set to air in Japan in April 2027.

At the center is Hina Katagiri, a modern high school student who wakes up in 1907 and gets mistaken for Hinako, her lookalike and Takaaki Hongo's betrothed. The reveal gives that pair voices—Yume Miyamoto as Hina and Takeo Otsuka as Takaaki—and comes with a teaser and new key art. Takashi Kamei directs at Tezuka Productions, with Yoko Yonaiyama handling series composition. The anime was announced in February 2026 and is scheduled to begin broadcasting in Japan in April 2027.
