Yoshinaga started making manga at comic markets before officially debuting in 1994 with The Moon and the Sandals in Hanaoto magazine. She's built a solid international presence—several of her works have been licensed overseas—and was featured in Professor Masami Toku's exhibition "Shojo Manga: Girl Power!" at CSU-Chico as one of twenty major mangaka who shaped shojo manga from World War II onward.

Beyond her professional serializations, she regularly self-publishes doujinshi, particularly Antique Bakery, and has also done fan parodies of classics like Slam Dunk, The Rose of Versailles, and Legend of Galactic Heroes. Not much is publicly known about her personal life, though she's mentioned being a Mozart fan in author's notes.

What comes through in interviews is her philosophy about storytelling. She's said: "I want to show the people who didn't win, whose dreams didn't come true. It is not possible for everybody to get first prize. I want my readers to understand the happiness that people can get from trying hard, going through the process, and getting frustrated." That sentiment—focusing on the struggle and growth rather than pure victory—seems to be core to what she does.
