Every year on May 21 is celebrated as “Detective Day” (探偵の日) in Japan, and to mark this special occasion, the online streaming platform ABEMA has gathered a lineup of detective and mystery anime for viewers to enjoy — from classic masterworks to trending titles currently in the spotlight. Here is what is worth watching.
名探偵コナン (Detective Conan) — The Great Detective in a Tiny Body
Detective Conan is adapted from the famous manga by Aoyama Gosho, serialized in Weekly Shonen Sunday since 1994. The story follows Kudo Shinichi, a brilliant teenage detective who is forced to swallow a poison by a shadowy organization, causing his body to shrink into that of a child. He then adopts the alias “Edogawa Conan” and works alongside friends to solve countless intricate cases.
The series’ appeal lies in its cleverly crafted tricks, the atmosphere that builds tension in each case, and the long-running overarching story involving the mysterious Black Organization — all of which have made it a nationally beloved detective anime spanning decades.
薬屋のひとりごと (The Apothecary Diaries) — Memoirs of a Pharmacist
The Apothecary Diaries is based on the novel by Hinata Natsu and is set in a fictional ancient Chinese-style imperial court. The protagonist, Maomao, is a young girl with an exceptional knowledge of medicines and poisons. Serving as a “food taster” in the inner palace, she uses her pharmacological expertise to unravel various mysterious incidents that occur within the royal court.
Beyond the thrill of the investigations, the complex interpersonal dynamics between characters — including the blossoming tension between Maomao and Jinshi — have also proven to be a major draw for fans.
ひぐらしのなく頃に (Higurashi: When They Cry) — When the Cicadas Cry
Higurashi: When They Cry is adapted from the visual novel by Ryukishi07. It is a mystery-horror anime set in the seemingly tranquil rural village of Hinamizawa, which conceals terrifying incidents and tragic fates beneath its quiet surface.
With mysteries that gradually reveal themselves layer by layer, carefully planted clues, and unexpected twists, this series has earned its reputation as a “masterpiece of mystery horror” with a uniquely distinctive atmosphere — combining a creeping sense of dread with puzzle-solving thrills that keep viewers gripped to this day.
