2010–2018 SUPER GiRLSEdit

Shimura Rika debuted as part of the first iDOL Street group SUPER GiRLS in 2010.

After Saori Yasaka graduated from SUPER☆GiRLS, she served as a second leader of the group from 2014 to 2016.

In 2012, Shimura released her first photobook, Rikataso.

In 2018, she graduated from SUPER GIRLS and iDOL Street on June 24.

When her pet dog died of a disease, she was deeply upset, and then took this opportunity to have a new dream, that she wanted to work to help sick animals. That is why she decided to quit being an idol.

When she told her fans that she planned to leave the group they were very sorrowful. Her last live took place in Differ Ariake and she moved on from SUPER☆GiRLS on June 24, 2018.

Personality Edit


She was loved by her fellow group members and many fans. She likes frolicking with her fellow group members. She belongs to ShimuKome Club made by Rina Miyazaki for fun. The ShimuKome club has 3 members, Rika, Rina and Koume Watanabe. Even though it is an unofficial group, many fans have accepted it.

She had some dreams that she wanted to realize as an idol, such as having SUPER☆GiRLS have an independent concert in Budokan, even though she performed at Budokan in iDOL Street Carnival, where the 3 idol groups that belonged to the label at that time, SUPER☆GiRLS, Cheeky Parade and GEM, performed.

Her personality is very delightful, and her smile made many people happy and encouraged. Also, she can't multiply, so she is called "Obaka" sometimes. Obaka means fool in English.
