Fall 2025 Premiere on TRAIN TV
The much-anticipated Uso Tantei Tomanto will begin its broadcast run in Fall 2025, specifically on October 6. The unique viewing platform for this series will be TRAIN TV, which broadcasts on the in-car displays of Japan Railways trains. This makes the anime accessible to commuters, offering quick, delightful mysteries during their daily travels. The series is planned to run for 26 episodes, concluding on April 5, 2026.
“Cute x Mystery” Adventures Unfold
Developed through a collaboration between San-X, known for characters like Rilakkuma, and Fanworks, recognized for the Sumikko Gurashi anime, Uso Tantei Tomanto is billed as a “cute x mystery” anime. The narrative follows the titular protagonist, Tomanto, a tomato-inspired detective, and his friends as they tackle various mysteries. Tomanto’s name is a playful combination of “tomato” and “mantle” (or “manto,” referring to the Inverness cape associated with Sherlock Holmes), highlighting his detective persona. The “authentic mystery” stories are solved using clever trivia related to vegetables and fruits, making for an engaging and educational viewing experience. Tomanto himself possesses a keen ability to spot “bright red lies” to crack cases.
The Narrative Hook: Vegetable and Fruit Trivia
A core element of the Uso Tantei Tomanto series is its integration of vegetable and fruit trivia into the mystery-solving process. This unique approach is expected to provide both entertainment and subtle educational value, appealing to a broad audience. With over 30 characters, each designed after various fruits or vegetables, viewers can anticipate a vibrant cast bringing these clever mysteries to life.
Key Production Team Behind the Series
The short anime boasts a seasoned production team. Yoichi Kato, known for his work on The IDOLM@STER Million Live! and Yo-kai Watch, is supervising and writing the scripts for the series. Directing the anime at Fanworks is Yoko Usami. Michihiko Suwa, a production planner with a notable background including Case Closed (Detective Conan) and Inuyasha, is also involved in the project. This collaboration between industry veterans and beloved character creators aims to deliver a fresh and charming mystery world filled with fun and surprises.
