Izumi Tōdō is a collective pseudonym used by the staff of the Japanese animation studio Toei Animation. The name was created for copyright purposes, allowing the studio to register a consistent creator credit for its productions. The origin of the name is derived from a combination of the studio's former name, Toei Doga, and the Oizumi studio where many of its productions are made. This pen name functions similarly to other well-known collective pseudonyms in Japanese media, representing the collaborative efforts of a production team rather than a single individual.

The pseudonym first appeared in 1999 on the anime series Ojamajo Doremi. Following the conclusion of that series, the Izumi Tōdō credit continued to be used on Ashita no Nadja, a fifty-episode anime that aired from 2003 to 2004 about a young girl who joins a traveling dance company in search of her mother. A manga adaptation of Ashita no Nadja was also published by Kodansha, with Izumi Tōdō credited as the creator.

The most significant and enduring work attributed to Izumi Tōdō is the Pretty Cure franchise. Beginning with the original Futari wa Pretty Cure in 2004, the pseudonym has been credited as the creator of every subsequent series in the metaseries, including Delicious Party♡Precure and its associated films such as Eiga Delicious Party♡Precure Yume Miru ♡ Okosama Lunch. The Pretty Cure franchise has grown into a major commercial property, encompassing hundreds of anime episodes, theatrical films, manga, and a wide range of merchandise.

The manga credited to Izumi Tōdō are typically adaptations of the anime series published in Kodansha's Nakayoshi magazine. For the Pretty Cure series, various illustrators draw the manga while Toei Animation, under the Izumi Tōdō name, is credited with the original work. This pattern holds for other series as well, where the manga version is published after the anime's broadcast.

In the anime industry, Izumi Tōdō is recognized as the official creator of some of Toei Animation's most successful magical girl properties. The consistent use of this pseudonym across different productions, from Ojamajo Doremi to the long-running Pretty Cure franchise, has established it as a significant brand name in the genre. The name is also used on spin-off media such as light novels and other adaptations, further solidifying its role as the official authorial voice for these corporate-owned properties.
