Izumi Todo is a collective pseudonym used by the Japanese animation studio Toei Animation. Rather than representing a single individual, the name serves as a studio pen name for the original creators and producers of various anime series, most notably the long-running Pretty Cure franchise. The credit functions similarly to other shared pseudonyms in the anime industry, such as Hajime Yatate for Sunrise productions or Saburo Yatsude for Toei's tokusatsu works. The name itself is derived from Toei Douga, the former name of Toei Animation, combined with the Oizumi Studio, reflecting its corporate origins.

The Izumi Todo pseudonym was first used in 1999 for the anime series Ojamajo Doremi. After that series concluded, the credit continued to be used for other magical girl productions that occupied the Sunday morning timeslot, including Ashita no Nadja. However, the pseudonym became most prominently associated with the Pretty Cure franchise, beginning with the original Futari wa Pretty Cure in 2004. Since then, every television series and theatrical film in the Pretty Cure franchise has been credited as an original work by Izumi Todo. The credit has appeared on over one hundred works, including television series, films, manga adaptations, and novels.

Among the notable works credited to Izumi Todo are the television anime series Delicious Party♡Precure, which aired from February 2022 to January 2023 as the nineteenth entry in the Pretty Cure franchise. The series, directed by Toshinori Fukazawa, centers on themes of cuisine, cooking, gratitude, and sharing, following four middle school girls who transform into the legendary warriors known as Pretty Cure to protect the world's dishes. Manga adaptations of the series, also credited to Izumi Todo and illustrated by the Futago Kamikita duo, were serialized in Kodansha's Nakayoshi magazine.

Theatrical film adaptations under the Izumi Todo credit include Eiga Delicious Party♡Precure Yume Miru ♡ Okosama Lunch, released on September 23, 2022, which was directed by Akifumi Zako with a screenplay by Jin Tanaka. Another film, Eiga Healin' Good ♥ Precure Yume no Machi de Kyun! tto GoGo!, was released on March 20, 2021, directed by Ryōta Nakamura with a screenplay by Ryunosuke Kingetsu. This film featured a crossover between the Healin' Good Pretty Cure and Yes! PreCure 5 GoGo! casts. An additional film, Eiga Mahō Tsukai Precure! Kiseki no Henshin! Cure Mofurun!, is also among the many theatrical works carrying the Izumi Todo original story credit.

The usage of the Izumi Todo pseudonym extends beyond the Pretty Cure franchise. It has also been applied to the Ojamajo Doremi series, including its sequel seasons and novel adaptations, as well as to other anime such as Musharambo, Kyousougiga, and Pop in Q. The consistency of the credit across different production staff, directors, and writers underscores its function as a studio-wide collective identifier rather than the work of a single creator.

In terms of artistic identity, works credited to Izumi Todo, particularly within the Pretty Cure franchise, are characterized by the magical girl genre, themes of friendship and personal growth, and the incorporation of specific motifs such as food, healing, or dreams that vary by individual series installment. The Delicious Party♡Precure series, for instance, prominently featured cuisine and the importance of shared meals as central themes.

The industry significance of the Izumi Todo credit lies in its representation of Toei Animation's production system and its role in one of the most successful and enduring magical girl franchises in Japanese animation. The pseudonym serves as a legal and creative framework that consolidates the contributions of multiple studio staff members under a single recognizable name, a practice that emerged in part due to historical copyright registration requirements in Japan. As the credited original creator behind the Pretty Cure franchise since its inception, Izumi Todo remains a foundational credit for a property that has spanned over two decades and continues to produce new television series, films, and related media.
