Kazuha Toyama

Kazuha Toyama is a recurring character in the Detective Conan mystery series, a close friend and childhood companion of Osaka detective Heiji Hattori, often drawn into the investigations surrounding young sleuth Conan Edogawa.

Kazuha Toyama steps onto the scene in Detektiv Conan #92 (2018), brought to life by Gosho Aoyama and Josef Shanel under the Egmont Ehapa banner in this Modern Age run of the beloved mystery series. She keeps remarkable company — sharing pages with sharp young detective Conan Edogawa, the formidable Heiji Hattori, and fan favorites Ran Mori and Kogoro Mori — placing her squarely at the heart of some genuinely thrilling casework. With six catalog appearances across a run stretching into 2025, she's a figure worth seeking out for any collector who loves their mysteries steeped in great ensemble energy.
