Please, MuscleSakura Hibiki (CV: Fairuzu Ai) & Machio Naruzou (CV: Ishikawa Kaito)
I bet there are still people who work out to this song.
The smash hit “Onegai Muscle,” the theme song of the popular series How Heavy Are the Dumbbells You Lift?, which was adapted into a TV anime in 2019, features Ai Fairouz and Kaito Ishikawa—who played the characters—on vocals.
Its upbeat, high-energy sound and insanely catchy melody that sticks in your head after a single listen made it a hot topic.
It’s truly one of the best anime songs to sing at karaoke.
Ai’s commanding vocal performance is so confident it’s hard to believe this was her first lead role and first character song, and Ishikawa’s light, perfectly timed call-and-response interjections are simply top-tier.
For karaoke, it might be fun to have one person handle the main melody while everyone else jumps in with the call-and-response parts!
Innovative☆Metamorpho~sis!Doma Umaru (CV: Tanaka Aimi)
Kakushinteki Metamorufoze!, the opening theme for the anime Himouto! Umaru-chan, was released in 2015 by Aimi Tanaka, who voiced the series’ protagonist, Umaru Doma.
It’s an uptempo track featuring a captivating series of ever-evolving synth sounds.
The lyrics, which depict the mischievous everyday life of little rascal Umaru-chan, are super cute, and many listeners will find Aimi Tanaka’s anime-style voice soothing.
It’s fun to have everyone sing the phrase at the end of the chorus or try adding some backing vocals.

Hyadain’s Kakakata☆Kataomoi-CHyadain
Hyadain is a music producer who now frequently appears on terrestrial TV music programs.
He provides songs for a wide range of artists, from idols to rock bands, but the song I’m introducing, “Hyadain no Kakakaka Kataomoi-C,” is actually Hyadain’s first single.
Its relentless melodic lines and the bright, poppy chorus hint at denpa-song vibes, don’t they? It really heats up at karaoke if you sing it as a duet! By the way, the original track’s female part is sung by Hyadain himself using a voice changer.
If you’re attacked by a grizzly ♡Kamiyado
When it comes to cute, girly denpa songs, “If a Grizzly Attacks You♡” tops the list.
It was released in 2019 by KAMIYADO, an idol group known for mastering a wide range of genres.
The dazzling electro sounds etched over a danceable beat are striking.
The heart-fluttering, girlish lyrics are addictively charming, and their conversational singing style is soothing, too.
Be sure to try it at karaoke with your friends and channel your inner idol.

How about cranking up the hype with a denpa song? This track by TrySail—the voice actor unit of Momo Asakura, Sora Amamiya, and Shiina Natsukawa—was released in April 2023.
It was used as the opening theme for the anime “My One-Hit Kill Sister: My One-Hit Kill Sister: Starting My Life in Another World With My Older Sister.” The fast-paced, totally unpredictable composition is insanely fun.
It flips between chiptune, a bass solo, and even a hard rock vibe—you never get bored.

Innovative☆Metamorpho~se!Doma Umaru (CV: Tanaka Aimi)
It’s a song sung by Aimi Tanaka that captured the hearts of many fans as the opening theme for the anime Himouto! Umaru-chan.
The protagonist’s true feelings—caught between her perfect public persona and her lazy at-home lifestyle—burst forth atop rapid shifts in tempo and an energetic sound.
Thanks to the deft vocal switching, the pure, elegant “beautiful younger sister” parts and the mischievous “himouto” parts flip back and forth so playfully that you can’t help but grin.
