Masami Katou is a Japanese voice actress born on September 26 in Gunma Prefecture, Japan. She has been active in the voice acting industry since the 2000s.

Information about her career is limited, but she is known to have worked on a number of projects, often under aliases. Her professional affiliations have included the talent agencies Arts Vision, RME, and Feathered.

Katou's body of work includes roles in various anime and video games, particularly in the adult-oriented genres. She sometimes performs under pseudonyms, including Kono Kanami and Nakano Shino. Some of the specific roles credited to her include Masumi Kurahashi in the anime Dai Saimin, Koma Yamatonoayanoatai in the anime Shikigami, and Mai Shimazaki in the series Inran OL Sawatari Tokiko ~ Onna-tachi no Inbi na Sugao ~. The example roles of Lapis in STAR Jewel and Natsuhime Suzaku in Haramasete Seiryū-kun! were not listed in the available search results, which may indicate that her work in such titles was performed under one of her aliases or that the information is not documented in standard databases.

It is important to note that a different individual with a similar name, Masami Katou (written with the family name characters 加藤雅己), served as an executive producer for the 2016 animated film A Silent Voice, but this is a separate person from the voice actress.
