Ichi Ichikawa is a Japanese manga artist recognized for creating works in the Boys Love genre. The creator, who is female, has been active professionally since 2010 and was born on July 22.

Ichikawa is best known as the author of the manga series Tadaima, Okaeri, also known in English as Welcome Home. This series, which began serialization in Fusion Product's Omegaverse Project anthology magazine on November 24, 2015, represents the creator's most significant and widely recognized work. The manga was recognized for its quality early on, being ranked as the 7th Best Manga at the Chil-Chil BL Award in 2017. The series has been collected into multiple tankobon volumes, with the fifth volume released in April 2024.

The story of Tadaima, Okaeri follows the daily life of the Fujiyoshi family, a same-sex married couple consisting of Masaki and Hiromu, and their two young children, Hikari and Hinata. The narrative is set in a society that classifies people into secondary genders, a setting typical of the Omegaverse subgenre, focusing on the family's experiences with both societal prejudice and the support of their community. The series blends elements of drama, romance, and slice-of-life storytelling.

The success of the manga led to a television anime adaptation, which was announced on Ichikawa's Twitter account in September 2023. The anime adaptation was produced by Studio Deen and directed by Shinji Ishihira, with scripts written by Yoshiko Nakamura. The series of 12 episodes aired from April 9 to June 25, 2024, on networks including Tokyo MX. The anime has been licensed for streaming by Crunchyroll outside of Asia.

In addition to Tadaima, Okaeri, Ichikawa has created other manga titles. These include Tenjou no Shita ni Koi, Ashita Asatte Sorekara Itsuka, and Shiba wa Kyoumo Baka. The creator's body of work is firmly established within the Boys Love genre, with Tadaima, Okaeri being noted as a work that established Ichikawa as a significant author in the field.
