Glass Heart (Netflix) Review :-
What I both love and struggle with when it comes to musicals is how easily I get swept away by the music—so much so that everything else fades into the background. That’s exactly what happened with Glass Heart, Netflix’s latest Japanese musical series. Featuring stunning compositions performed by some of the finest talents in Japan’s music scene, it had me completely immersed in its melodies.
After a chance encounter, Saijo Akane is swept into a new band alongside legends Fujitani Naoki, Takaoka Sho, and Sakamoto Kazushi. What follows is an uphill journey as they strive to strike the perfect harmony—crafting music that not only clicks among themselves but leaves audiences spellbound. You can’t help but be drawn in by their soulful sound and the electrifying musical sequences where they sing, dance, and pour their hearts into every note.
These are the moments where the series truly comes alive—the adrenaline practically leaps off the screen. Much like the characters, completely immersed in their stage personas, viewers find themselves pulled into the performance, feeling every beat, breath, and breakdown. It’s magnetic. The actors radiate a sense of freedom in these scenes, and I found myself utterly captivated by their presence. TENBLANK’s stage energy—its chemistry, raw intensity, and the emotional gravity of real music—delivers a cathartic punch rarely seen in recent television.
With songs crafted by some of Japan’s most influential artists—including Yojiro Noda of RADWIMPS, Taka from ONE OK ROCK, Zarame, and Yoohei Kawakami of [Alexandros]—the series places a strong emphasis on its music, and that care resonates in every scene. Each performance, whether on stage or off, feels charged with magic. The actors reportedly trained to play their instruments for the show, and their dedication is evident—it adds a layer of authenticity that elevates the entire production.
That said, the moments between performances don’t always hold the same spark. The energy dips noticeably, weighed down by the characters’ emotional baggage and backstories, which at times feel like they slow the pace. Granted, the show does aim to explore the messy, complex lives of musical prodigies, so that heaviness is part of the narrative—but it can make you wish you could fast-forward to the next performance. Still, those slower beats aren’t without merit; many of the more dramatic scenes remain engaging and deliver just enough to keep you hooked.
Glass Heart (Netflix) Trailor :-
On the other hand, the character I felt most conflicted about was Saijo Akane, played by Miyazaki Yu. Despite her central role, Akane feels disappointingly underdeveloped—her character operates in just two emotional modes and offers little depth beyond that. It’s especially frustrating given how much screen time she receives.
In contrast, Satoh Takeru shines as Fujitani Naoki, a flawed and enigmatic musical genius. His layered performance was a standout for me. And then there’s Machida Keita, who completely won me over—he brings a raw, effortless charm to his role that feels perfectly in tune with the spirit of a guitarist.
Final Thought
Glass Heart was an enjoyable watch from start to finish. While it occasionally flirts with slower pacing, it manages to stay engaging throughout. Despite its imperfections, it’s a solid series that knows how to keep you invested.
“Glass Heart” is now streaming on Netflix.
