You’ve probably heard the chorus before—maybe on TikTok, maybe blasting at a con, or maybe on a late-night anime binge. Japanese anime songs, or “anisongs,” are no longer just theme tunes—they’re global pop culture events. With bold melodies, heart-pounding emotion, and visuals to match, they’ve become the new obsession for fans around the world, especially Gen Z.
During and after the COVID-19 lockdowns, anime soundtracks started dominating Spotify charts, YouTube mashups, and club nights. Whether it’s an opening theme that hits like a rock anthem or a sentimental ballad that makes you cry over fictional characters, this music is hitting hard.
From nostalgic bangers like We Are! from One Piece to new-gen hits like Idol from Oshi no Ko, anime music is now a legit genre of its own. And with over 70% of listeners under 29, one thing is clear: Gen Z didn’t just discover anime songs—they made them global.
What Is No. 1 Anime in Japan? Just Ask the Music Charts
So, what is the No. 1 anime in Japan right now? While shows like Demon Slayer, Jujutsu Kaisen, and One Piece battle it out for the crown, their anime songs are crushing global charts. These aren’t just background tracks—they’re the heartbeat of entire fandoms.
Take Gurenge by LiSA, the fiery opening for Demon Slayer: Kimetsu no Yaiba. It didn’t just hype fans—it crossed into the mainstream, showing up in Olympic performances and TikTok trends. Another example? YOASOBI’s Idol for Oshi no Ko, which topped the Billboard Global Chart—yes, globally.
These aren’t isolated wins. The rise of popular Japanese anime songs reflects a wider trend where anime isn’t just influencing Japanese culture—it’s influencing the world. And younger fans aren’t passive listeners—they’re remixing, sharing, and screaming the lyrics back at concerts. It’s music built for passion and playback.

Why Gen Z Can’t Get Enough of Anisongs
Anime music didn’t just sneak into Gen Z’s playlists—it kicked down the door. With the pandemic giving everyone more screen time and streaming access, anime became a digital escape. The visuals were fire, but the music? That’s what stuck.
Gen Z grew up online, where aesthetics, vibes, and emotional storytelling rule. Anisongs check all those boxes. The genre-jumping sounds—from jazzy intros to EDM outros—fit perfectly into TikToks, edits, and mood playlists. Plus, the lyrics often hit on universal themes like hope, pain, growth, and dreams.
But it’s not just about escapism—it’s also cultural discovery. Anime music has introduced millions of young fans to Japanese pop, rock, and even classical composers like Joe Hisaishi. It’s global, inclusive, and deeply personal. And for many Gen Z listeners, it’s not just background music—it’s their identity soundtrack.
Japanese Anime Songs Are More Than Just Openings
Japanese anime songs aren’t limited to intros—they’re immersive, cinematic experiences. From OPs to EPs (end themes), insert songs, and character tracks, these tunes shape how we feel about the story and its characters.
And the popularity isn’t limited to Japan anymore. Want proof? Search for popular Japanese anime songs on Spotify or YouTube and you’ll find playlists with millions of followers. Fans don’t just stream the music—they memorize it, remix it, and make it part of their daily routine.
A standout example is Ado’s New Genesis from One Piece Film: Red. Performed in-character as Uta, it captured complex emotions in one banger. Or how about RADWIMPS’ emotionally cinematic scores for Your Name and Suzume? These songs don’t just support the visuals—they elevate them into legendary moments. It’s why anime music is winning new fans across languages, borders, and generations.

Live Shows, Club Nights & Viral Fame: Anime Music Goes IRL
Anime music is no longer confined to your headphones. It’s filling arenas, fueling parties, and headlining festivals. From sold-out concerts at London’s O2 Arena to lowkey club nights hosted by collectives like Anime & Chill, these songs are now live experiences.
When you see 20,000 fans waving glowsticks and screaming lyrics in perfect sync—most of them under 30—you get it. These aren’t niche fandom moments. They’re communal, emotional explosions. And Gen Z? They’re all in.
Social media plays a massive part. Anime songs go viral on TikTok and YouTube, then loop back into the mainstream. Remix culture, cosplay performances, fan edits—it’s all part of the same vibe. Even Western artists are jumping in. Think Billie Eilish name-dropping anime characters, or indie rappers writing bars around One Piece.
Bottom line? Japanese anime songs are global now—and they’re just getting started.
