Career
2010–2014: BiS and Akishibu Project
On 25 October 2010, Yokoyama Rina was revealed to be one of the four founding members of new idol group BiS, under the stage name ヨコヤマリナ, which is her name written in katakana. As a member, Yokoyama Rina participated in BiS' debut single, "Taiyou no Jumon", and their debut album, Brand-new idol Society. On June 2011, Yokoyama Rina decided to leave the group due to her disagreements with the direction the group was taking. She then worked as a model to the now-defunct fashion magazine Nicky under her name written in kanji. On 5 October 2012, Rina Yokoyama announced that she was creating a new idol group named Akishibu Project with the aim of "merging the cultures of Shibuya with Akihabara." During this time, she went by the stage name "Rinahamu". Originally composed of Rinahamu and two other members, the group expanded and held regular performances at Twinbox Akihabara. Rinahamu left the group on 11 May 2014, and a graduation concert was held in her honor. She also attended BiS' dissolution concert on 8 July 2014.
