Among her most noted works are the manga Toward the Terra and Kaze to Ki no Uta, which are noted for being pioneering series of the 1970s and 1980s. She received the 1979 Shogakukan Manga Award for shōjo manga and shōnen manga respectively for Kaze to Ki no Uta and Terra e..., and the prestigious Seiun Award for science fiction manga in 1978 for Terra e.... She is regarded as "one of the first successful crossover women artists" to create both shōjo and shōnen manga. Many of her series have been adapted into anime, including Terra e... in 1980 and 2007, Natsu e no Tobira in 1981, and Kaze to Ki no Uta in 1987.
