Vocaloid songs that start with 'O'

If you’ve come here, chances are you like Vocaloid songs.

It’s been a long time since Hatsune Miku’s debut in 2007, and countless masterpieces have continued to be born.

In the meantime, the Vocaloid scene has seeped so deeply into the times and culture that we even have the term “Vocaloid-native generation.”

Now then, what I’m introducing this time is a selection of Vocaloid tracks whose titles start with the letter “O.”

Be sure to read to the end and find a new favorite track!

Vocaloid songs starting with 'O' (141–150)

Operation Wake-Upyukopi

Yukopi – Operation: Staying Awake (feat. Kaai Yuki)
Operation Wake-Upyukopi

Released in September 2024 by Vocaloid producer Yukopi, this work is a humor-filled pop number themed around a day–night reversed lifestyle.

It’s a collaboration track with Pmarusama.

Built on an electropop foundation with a brisk rhythm, it creates a fun world through its timbres alone.

The distinctive vocals of Kaai Yuki are another highlight.

It’s a cute, feel-good cheer song that makes you want to sway and hum along!

Childish Warreoru

I think the biggest selling point of this song is, above all, its up-tempo pace and distinctive sense of rhythm.

When it comes to actually singing it, capturing that unique feel might be a bit difficult, but if you can sing it cleanly from start to finish, it’ll sound really cool.

Princess Pactwari to ari

A song by Wari Toari, who began working as a Vocaloid producer in 2021.

It’s their second Vocaloid track, featuring loud, technical guitar, a bassline that gives the song a powerful swell, and a light, fast-paced drum beat—an irresistible number for rock fans.

The cute, catchy melody riding on the straightforward rock sound gives you energy.

I recommend listening to it when you just can’t get your motivation up.

OptimistImanishi

Imanishi “Optimist” feat. Hatsune Miku

A sad piano rock number that sings of giving up on oneself.

It’s producer Imanishi’s debut and breakout hit, released in 2021.

A highly addictive waltz that makes you want to call it a “bundle of pure style.” Both the melody and the lyrics give the impression that the protagonist’s thoughts are spilling out in an unending stream.

“I know it’s not right, but this is all I can do.” Haven’t many of us felt that way at some point?

Our Neighbor’s UniverseKarurosu Hakamada

Carlos Hakamada (SaizeP) feat. Seikai / Our Neighbor’s Universe – Carlos Hakamada (SaizeP) / Universe Next Door

Carlos Hakamada, a Vocaloid producer also known as “Saize-P.” “Otonari-san Chi no Universe” is a denpa-style track he created featuring the virtual singer Hoshikai.

While the song centers on rapid-fire verses, it deliberately shifts the rhythm and pitch here and there to create a more chaotic vibe—that’s the key.

Under the band name Dynamic Jienzu, Carlos Hakamada has produced many high-energy songs as well.
