Yamaguchi Nonoka (山口乃々華) is a Japanese performer, actress and model. She is a former member of the group E-girls.
Yamaguchi Nonoka was born on March 8, 1998 in Saitama Prefecture, Japan. She has a sister who is a high school teacher.
In 2007, when she was only in elementary school, she won the Reader's Model Special Award for the magazine Shogaku shinensei. According to Yamaguchi herself, the descision to apply for this model competition was a spontaneous one. Her interest in the entertainment industry developed when she heard her mother saying, "This is so cute.", while looking at a fashion magazine, and desired to be praised in some way too. In 2008, she won the runner-up prize for reader's model for the magazine Shogaku gonensei.
Yamaguchi started dancing early on in her childhood and did ballet from the age of three to fourth grade. Afterwards, she became interested in cheerleading. However, she realized cheerleading classes were too exhausting for her due to the forced cheerfulness. Since the school she went to had a girls' hip-hop program, she decided to give it a try in fifth grade. The teacher of this program had a connection with EXPG and suggested her to participate in a vocal audition for Happiness. Although Yamaguchi didn't pass this audition, she did pass the EXPG special student audition. As a result, she started attending EXPG Tokyo in 2009.
In 2010, Yamaguchi won the grand prix award at the 18th Pichi Lemon Audition, and started working as an exclusive model for the magazine Pichi Lemon.
In 2011, she participated of the EXILE Presents VOCAL BATTLE AUDITION 3 ~For Girls~ in the dance section and successfully passed the audition. As a result, she became a member of the pre-debut group bunny and started her career as a dancer.
In July, 2013, she made her acting debut as a member of the dance club in the TV drama Ashita no Hikari wo Tsukame -2013 Natsu-.
In December, 2014, she graduated from Pichi Lemon, appearing for the last time as an exclusive model of the magazine in the January 2015 issue.
On December 22, 2019, with the announcement of E-girls' disbandment set for around the end of 2020, it was revealed that Yamaguchi will focus on acting and modeling activities.
Yamaguchi was chosen to narrate a documentary about the success of fellow LDH group Girls2 titled Girls2 ~The Miracle of 9~ which aired on TV Tokyo on March 22 and March 29, 2020. On December 31, she left E-girls with the group's disbandment. After the disbandment, her profile was moved to the actor section of LDH.
On February 4, 2021, she released her first book titled Nonopedia Kokoro no Kioku, which includes everyday stories of little joys and fears during her time as a member of E-girls, the inside story of the dissolution of the group and her hopes for the future. Additonally, it is a collection of essays she published in her web series Nonopedia on GINGER WEB. Originally, when she was between 18 and 20 years old, each member of E-girls used to exchange their daily feelings with the staff in the form of a "diary," and this is what inspired her to write. According to Yamaguchi herself, writing led her to look at herself in a new light and to read books.
