__Introduction__
Kana Hanazawa is a voice actress, actress, singer, former child actress, and talent represented by Office Osawa. In July 2020, she married fellow voice actor [Kensho Ono](https://anilist.co/staff/95819), whom she had been dating since 2017. They separated in 2025 due to differences in lifestyle, which made it difficult to spend time together. 

__Early Career__
Hanazawa originally became a child actress at the age of 8. Amongst other roles, she starred in the well-known TV school show _Appare Sanma Daisensei_ and the TV series _Gakkou no Sensei_. At that time she was contracted to Big Apple, and later to Five Eight and Smile Monkey.

__Voice Acting Career__
At the age of 14, she made her voice acting debut in 2003 as Holly in _[Last Exile](https://anilist.co/anime/97/)_. Three years later in 2006, she was selected for a major role in TV Tokyo's anime mecha series _[Zegapain](https://anilist.co/anime/878/)_. She was playing the main character's childhood friend, [Kaminagi Ryouko](https://anilist.co/character/2578/), and her performance was one of the main reasons for the character's popularity amongst fans. It was afterwards that she came under contract at prestigious voice acting talent agency Office Osawa in 2007.

Hanazawa went to university in 2007, while at the same time, she began to make her mark as a voice actress. She was voted in 2010 as "Best Female Voice Actress" by listeners of the radio program Nonko and Nobita's Anime Scramble. She graduated from university in 2011, and in the same year became a full-time voice actress.

Her first album Claire was released on February 20, 2013, and her second album 25 was released on February 26, 2014. She released an album title Blue Avenue in April 2015 and went on a concert tour starting at the Nippon Budokan on May 3.
