Maomao and Jinshi Pose in Front of the Venue Itself
The Osaka-exclusive key visual, revealed in a report from the Japanese entertainment news outlet Oricon News, shows Maomao and Jinshi standing against a backdrop of the Hanshin Umeda Main Store, the same Umeda district department store that hosts the exhibition. The artwork is credited to Touko Shino (しのとうこ), who illustrates the original novels.
That same artwork anchors the goods-bundled ticket bonus. The Osaka-limited pass and neck strap set features the new key visual on the front of the pass, with the color frontispiece art from the novels' fourth volume on the back.
There is also a freebie at the door. Visitors receive "Okusuriya Techo," an A6 notebook designed to double as a working medicine notebook, the prescription-record booklet used at Japanese pharmacies. It's handed out while supplies last.
A Novel-First Exhibition, Not an Anime One
"Poison and Medicine, Science and Mystery" is built around the original light novels by Natsu Hyuuga (日向夏), published under Imagica Infos' Hero Bunko imprint, rather than the TV anime. The books follow Maomao, a poison-obsessed apothecary who solves medical mysteries in the rear palace of a Chinese-inspired imperial court, and Shino's illustrations give the characters their original look.
The exhibition debuted at Space 634 inside Tokyo Solamachi, the shopping complex at the base of Tokyo Skytree, where it ran from December 5 to 25, 2025. Imagica Infos announced the Yokohama and Osaka venues in April 2026 through its Hero Bunko store site.
It is a separate event from the TV anime exhibition, which made its own Osaka stop at the Daimaru Museum in Umeda in summer 2025. That makes this Umeda's second Apothecary Diaries exhibition in two years, this time with the novels' art at the center.
Looking Ahead
The Osaka run of "Poison and Medicine, Science and Mystery" opens July 15 and closes July 27, 2026, at the Hanshin Umeda Main Store, with tickets listed through the Japanese ticketing service Lawson Ticket. A Yokohama venue was announced alongside Osaka, with details posted through the Hero Bunko store.
No plans have been announced for the exhibition to travel outside Japan. English readers can keep up with the source material either way: the light novels are published digitally in English by J-Novel Club, and Square Enix began releasing print editions in May 2024.
