Aiuchi Rina

Aiuchi Rina promoting LAST SCENE (2010)

Aiuchi Rina (愛内里菜) is a former Japanese pop artist who was under the GIZA studio label. When she debuted, her music was a mix of trance, dance, and pop; however, after she started self-producing her songs, Aiuchi incorporated rock influences in her music. Despite her minor setbacks, she remained a prominent name in the Japanese music scene and is one of GIZA's most popular artists. In 2010, Aiuchi announced that she was retiring from music because of health reasons.

In August 2013, she legally changed her name to Rika Kakiuchi (垣内りか). She later explained via her blog that she did so because of, among other reasons, her desire to separate her identity as a former singer from her post-retirement work as a producer of her "BonBon Copine" brand of pet-related items and services.
