Pretz Matsumoto is a Japanese manga artist, or mangaka, recognized as the original creator behind the anime and manga series Uchi no 3 Shimai. Born on January 12, 1974, in Saitama Prefecture, Japan, Matsumoto is female and has blood type O. The creator is credited under the name Pretz Matsumoto, which is also written in kana as まつもと ぷりっつ.

The most significant and well-documented work by Pretz Matsumoto is the Uchi no 3 Shimai franchise. The series began as a blog written by Matsumoto in 2005, which documented the humorous daily lives of raising three young daughters. This blog served as the foundation for a manga adaptation. The manga, a four-panel or 4-koma style comic titled Uchi no Sanshimai, was serialized in Manga Club magazine, which is published by Takeshobo. The manga series spans sixteen volumes.

The success of the manga led to a television anime adaptation, also titled Uchi no 3 Shimai, which was produced by the prominent animation studio Toei Animation. The anime series was directed by Izumi Todo and aired on TV Tokyo for 102 episodes from April 8, 2008, to March 30, 2010. In the anime credits, Pretz Matsumoto is officially listed as the original creator. The story follows the everyday adventures of three sisters named Fuu, Suu, and Chii, and their parents, exploring themes of family bonds, sibling dynamics, and the simple, often comedic moments of childhood from a warm and observational perspective.

Pretz Matsumoto has maintained a presence on social media under the username 3furlongpu. The body of work, particularly Uchi no 3 Shimai, holds significance as an example of a multimedia franchise that successfully transitioned from a personal blog to a serialized manga and finally to a long-running television anime, all while maintaining its core identity as a gentle, slice-of-life comedy for a family and child audience.
