Biography

About Risa Otoshima

Edited by the community

Risa Otoshima is a Japanese J-pop idol from Fukuoka, Japan. She is a founding member of =LOVE and a former member of HKT48 and FUKUOKA Hakata Minyon. At 5'3" with a slim build, black hair, and brown eyes, she brings a petite presence to the stage.

Risa's idol career began early, around age 16, and she has been active since 2015. Her time with HKT48 was notably brief, lasting only 9 days. She was dismissed after it was revealed she had participated in auditions while under another agency, which broke the rules. That dismissal, announced on July 21, 2016, still stands as the shortest tenure in HKT48 history. She likes salad and strawberries.
