Minako Kotobuki: Movies & Box Office

Minako Kotobuki was born on September 17, 1991 in Kobe, Hyōgo Prefecture, Japan, and survived the Great Hanshin earthquake at the age of three, an event that profoundly shaped her resolve to pursue performance arts. After watching the 1997 film Chikyuu ga Ugoita Hi (The Day the Earth Moved), she became fascinated with storytelling and decided to become a voice actress, a dream she nurtured throughout her elementary school years. She entered the entertainment industry in 2005, initially landing minor roles before her breakthrough came with the role of Tsumugi Kotobuki in the widely acclaimed anime K‑On! which aired in 2009. This role not only showcased her vocal talent but also launched her music career, as she performed both the opening and ending themes alongside her co‑stars. Kotobuki quickly became known for her versatile voice, portraying characters ranging from the heroic Karina Lyle/Blue Rose in Tiger & Bunny to the magical Rikka Hishikawa/Cure Diamond in DokiDoki! PreCure, and the earnest Touko Nanami in Bloom Into You.

Beyond voice acting, Minako has built an impressive musical résumé as a member of the J‑pop idol group Sphere, formed by her K‑On! castmates under Sony Music's Music Ray'n label. The group’s debut single “Future Stream” dropped in April 2009, and Kotobuki has since released three solo albums—My Stride (2012), Tick (2014), and Emotion (2018)—alongside a string of chart‑topping singles such as “Shiny+” and “Black Hole”. Renowned for her rapid learning ability, she is praised by peers for mastering choreography and harmonization with remarkable speed, often guiding her group’s dance routines. Kotobuki’s live performances, including her nationwide “Our Stride” tour, frequently feature her playing keyboard, echoing her character’s talents in K‑On!. In July 2023 she announced her marriage to a non‑entertainment partner, keeping details private, and remains a beloved figure in both the anime and J‑pop communities.
