Nanaho Misumi is a Japanese female voice actor born on August 21 in Hakodate, Hokkaido. Her birth name is Naho Nakaya. She is affiliated with the talent agency rock'n'banana but is currently working as a freelance voice actor. Her blood type is A.

Misumi began her career in 2004, primarily working in the field of adult computer games. She has a strong interest in video games of all types and has described herself as having a deep, hobbyist-level knowledge of them. She is the twin sister of fellow voice actor Shiho Nakaya. Due to her voice, Misumi is often cast in the roles of younger sister characters, a contrast to her twin sister who frequently plays mature, older women.

A significant part of her early career was her role as Alice Hosen in the 2004 game Canvas2: Akane-iro no Palette. Her dedication to her craft was demonstrated when she personally purchased the PlayStation 2 version of the game to study the performance of Kae Mizuhashi, who voiced the same character in that adaptation. This anecdote highlights her commitment to improving her acting skills.

Her filmography is extensive and consists almost entirely of roles in adult and erotic video games produced between the mid-2000s and mid-2010s. Among her many credited roles are Koharu Mizusaki in Parfait: Chocolat Second Brew, Kureha Nanao in Rondo Leaflet, and Otoha Minamida in a game from the Rondo Leaflet series. She also voiced Momoko Ishizuki in the Pia Carrot series and Kaho Yoshizuki in Doki Doki Majo Shinpan!.

One of her roles was Rumi Kuzuha in the 2009 game Yume Kui: Tsurumiku Shiki Game Seisaku. Her other notable roles from this period include Ayaka Touno in Natsukura, Ritsuko Watase in Hōō Senki - MuMU, and Kyōko Izumi in various titles. She continued to work in the industry through the early 2010s, with credits such as Momo Midorifuchi in Shaman's Sanctuary: Miko no Seiiki in 2010 and Aika Koshō in Sukui no Serenade in 2015.
