Early life

As an only child, Mayuka is known for her reserved nature and rarely publicizes her personal relationships.

In 2019, Mayuka participated in the survival reality show Nizi Project organized by JYP Entertainment to form a Japanese girl group. In June 2020, she ranked 7th in the final of Nizi Project and officially became a member of NiziU, as the group released their pre-debut digital EP Make You Happy.
