Classic songs sung by Kasane Teto. Recommended popular UTAU tracks

Created in 2008 as one of the April Fools’ pranks on the internet forum 2channel and later actually turned into a UTAU voicebank by volunteers, “Kasane Teto.”

This time, we’ll introduce popular and classic songs sung by Kasane Teto, who has such an unusual origin story.

The voice model was Namine Momoyo Koyama, who was a junior high school student at the time, yet her singing voice carries a somewhat mature vibe.

When it comes to UTAU, these are exactly the wonderful songs you’ll want to introduce first!

A masterpiece sung by Kasane Teto. Recommended popular UTAU songs (1–10)

nth dimensionNEW!Satsuki

This is a Kasane Teto SV song by Satsuki, released to coincide with “Teto Day” in October 2025.

Beginning with the question, “If words could live on for decades, what could I say here?”, it brings themes like time, the meaning of words, and the uncertainty of existence to the surface.

It features a heavy sound and dynamic pacing throughout, and Teto’s firm, focused vocals really shine.

Satsuki’s signature odd meters and bold arrangements are, of course, alive and well.

Highly recommended for those interested in expressions that break through conventional boundaries!

The debut work from the music circle Sebura-bu, which begins with an emotional guitar performance.

It was apparently created based on an original novel written by member Shun Narita.

The softly rendered illustrations, combined with the story, create an outstanding atmosphere.

Even though different vocals are coming from the left and right, the sense of unity as a song never falters… it’s a captivating piece.

It’s a track by the Vocaloid producer Frokuro, who creates from unique and epoch-making ideas, released in 2020.

The standout charm of this song is, above all, the vocal work.

With simultaneous left-right singing that rhymes and even kicks off a word-chain game, it delves deeply into playful wordcraft.

Despite such an artistic approach, it remains musically catchy—perhaps because it spotlights the rhythms of Japanese.

Or rather, it’s a Kasane Teto song so compelling that it’s hard to express its appeal in words.

Letter Addressed to the Blacked-Out WorldFrokuro

Letter to the Blacked-Out World Frokuro

How do people come up with ideas like this…? This song is by the Vocaloid producer Frokuro, also known for works like “Kotoba no Obake ga Miteiru” and “Tada Sentaku ga Atta,” and it was released in 2022.

The “blacking out” referenced in the title is rendered in the vocals as a so-called beep sound, resulting in a track that makes you obsess over its true meaning.

What exactly is that sound? What words are hidden under the redacted lyrics? Frokuro’s works are always filled with mechanisms that make you suddenly catch your breath once you notice them, so I encourage you to dive in and theorize.

Even if you tell me everyone feels that way sometimes, I can’t believe it when they all go around living with big smiles on their faces.Lightly Salted Index

I think it works best when you’re in a “I’m sick of everything” kind of mood! It’s a piece by Vocaloid producer Usushio Shisuu, released in 2015.

This song unfolds with a very catchy band sound, and its biggest feature is the lyrics filled with unadorned words.

The message makes you nod along, as if it’s voicing the honest feelings you want to say in everyday life but can’t.

This straightforward music might just save your heart.

How about letting emotional guitar rock tear at your heart? This track by Vocaloid producer 4ma15 was released in 2017.

Precisely because it’s a simply structured band sound, every single word hits home.

The lyrics feel like they reflect emotions rising straight up from the depths of the chest, and that’s what makes them so good.

“Being in a bright mood isn’t always the right thing to do.” It makes me feel like I can forgive myself—and it saves me.

Perfect for those nights when loneliness creeps in.

This work is striking for its vocals swaying over a near-futuristic electric sound.

It’s a track by the Vocaloid producer Miriko, also known as the creator of “Don’t Kill Mary Sue,” released in 2017.

Teto’s fragile singing voice matches the steady, understated melody line, making your chest tighten.

Listening to it feels like your whole body is being wrapped in sound.

The sorrowful message in the lyrics, directed at someone dearly important, also hits home—an outstanding Teto song.
