The Apothecary Diaries Season 3 Starts October 2, New Trailer and Opening Theme Revealed
The wait is over for fans of The Apothecary Diaries (Kusuriya no Hitorigoto). According to Anime Corner, the third season will begin airing in Japan on October 2. A new promotional trailer and key visual have also been released. The season's opening theme will be performed by Yorushika, one of the beloved bands in the Japanese music scene. This announcement has become one of the most exciting developments for viewers closely following the series.
Starting from Natsu Hyuuga's web novel and continuing under the Hero Bunko label, The Apothecary Diaries follows the young pharmacist Maomao as she gets entangled in medical mysteries and court intrigues within the imperial palace. Nekokurage's manga adaptation has also brought new readers to the story. The anime's first season aired in 2023 and quickly gained a huge fanbase worldwide. The second season continued that success when it aired in the first half of 2025. The third season is expected to once again highlight Maomao's intelligence, composure, and sharp observational skills.
On the production side, the anime is credited to OLM and TOHO animation. Yorushika taking on the opening theme is seen as a sign of the production's careful preparation. The series, known for its notable music choices in previous seasons, has once again managed to make waves with a different musical direction. The new key visual showcases how Maomao and other characters in the palace are positioned once more in a poetic atmosphere.
The new season starting on October 2 will bring up both hints about the relationship between Jinshi and Maomao, as well as unresolved secrets. Fans of Kusuriya no Hitorigoto can expect an increased dose of both detective elements and dramatic developments with the new episodes. The visual richness indicated by the trailer shows that the production team has maintained its high standards. With the start of the season, The Apothecary Diaries seems poised to once again be one of the most talked-about anime in the world.
