On July 31, 2025, Netflix will launch Glass Heart, a Japanese musical drama inspired by the renowned novel by Mio Wakagi (which was published from 1993 to 2011). The narrative follows a university drummer who faces an unjust expulsion from her band but discovers a new opportunity when a gifted musician finds her. The show promises to blend live musical performances with heartfelt storytelling centered around themes of passion, music, and second chances.
Guided by directors Kensaku Kakimoto and Kotaro Goto, this drama boasts high-quality musical production, featuring an original soundtrack by Yojiro Noda from RADWIMPS. The series is distinguished by its authentic musical portrayals, as the actors genuinely play their instruments, providing a distinctive immersive experience within the realm of J-drama.
Akane Saijo: The Drummer on a Quest for Redemption
Akane Saijo (Yu Miyazaki) is a university student with a passion for drumming who experiences a heartbreaking injustice when she is expelled from her band just before their debut. Her true talent and relentless spirit attract the attention of Naoki Fujitani, a reclusive yet brilliant musician who sees her potential. Akane’s journey symbolizes the struggles faced by many young artists as they navigate obstacles in the pursuit of their aspirations.
Yu Miyazaki delivers a compelling and authentic performance, embodying both the fragility and resilience of a young artist eager to validate her capabilities. Her character’s growth throughout the series illustrates how a love for music can help overcome even the toughest challenges.
Naoki Fujitani: The Mysterious Musical Prodigy
