Soma started drumming at age 2 and performing in concerts at age 4.[2] In 2015, she began playing in her family's band, Kaneaiyoyoka,[1] with her parents, Akifumi and Rie Soma.[6] At age 6 during her kindergarten years, she released her first music CD.[7] Soma and her family have discussed how Japan and its traditional school system has been stifling to her music career and aspirations, preventing her from playing drums during her school life because of her higher skill level than the other students. She also spoke out against the idea of collectivism in Japan that prevents individuality and the idea of any individual person standing out as unique.[8]
She has appeared twice on the American television talk show Ellen[10] and in advertisements for sports apparel maker Nike, Italian luxury fashion brand Moncler and Japanese casual wear designer uniqlo. Her online videos have been viewed over 68 million times.[1] She was listed by Newsweek Japan as one of the top 100 Japanese people that the world respects.[11]
