The Apothecary Diaries Film Reveals Kenshi Yonezu Theme “Haru ga Tomori,” Full Trailer and Key Visual

The song accompanying the film has been announced! The theme for *The Apothecary Diaries: The Late Consort’s Hidden Treasure*, opening Friday, December 11, is “Haru ga Tomori” by Kenshi Yonezu. The official portal announced it October 22, and the TOHO animation channel released a full trailer featuring the song.

The Mystery Takes Shape in the Trailer

The trailer opens with the theme’s lively piano. Maomao and Jinshi travel to Minamishu, governed by the Mi clan, to return the body of Ruoqing, a middle consort who died five years earlier, to her homeland. There they meet Yinshan, who served Ruoqing, and Muqing, the youngest son of the clan.

The tone shifts when water-pirate leader Shuishe appears seeking treasure hidden by a former clan leader. A scene even shows someone stealing the body’s head, hinting at overlapping mysteries.

Inspired by Children’s Songs

Yonezu completed the song after discussions with original author Natsu Hyuga and director Norihiro Naganuma. He said he read the screenplay closely and was strongly influenced by the children’s songs “Tulip” and “Antagata Dokosa.”

A new key visual gathering the film’s characters and a character relationship chart were also released. We covered the character videos in articles including this one on Ruoqing and Yinshan.
