Early Life[]

Ishimura Maiha was born on November 20, 1992 in Chiba, Japan to a couple whose names are undisclosed.


On June 30, Ishimura successfully passed the Hello! Project Kids Audition and joined Hello! Project as one of the fifteen Hello! Project Kids.[1]


In 2004, she was one of the eight members selected to form Berryz Koubou. She was known for "Maiha-Man", an ascii art character based on her.


She graduated from the group and from Hello! Project on October 2, 2005, at the end of their 2005 Fall concert tour, making her the second H!P member who had her own Graduation Concert outside of Morning Musume (the first being Heike Michiyo). The official reason stated was that she wanted to continue with her schooling full-time.

It was rumored at the time of her departure that her junior high school did not allow her to work as an idol. There was later news about her attending Shinagawa Étoile Girls High School, an elite private school in Tokyo, somewhere near Chiba. This confirmed the rumor, as the school's regulations forbids its students to work after-school.


In 2012, Ishimura began working at her father's eel shop.


In 2014, Ishimura signed under Oscar Promotion. This marked her first appearance in the entertainment industry since her graduation in 2005, 9 years previous. She remained signed under the agency until she retired once more in 2015.
