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” (131–140)

Hatsune Miku - Warm and Cozy in the Bath (by FuwariP)
Warm and fluffy in the bath P

It’s a cute, heartwarming song that makes you feel all warm and cozy as you listen.

It was originally supposed to be unlisted, but the Vocaloid producer accidentally made it public, and without that, it probably wouldn’t be as well-known as it is now.

Also, a masculine voice comes in partway through, making it sound like a father and his young daughter singing together while taking a bath, so it’s perfect for Father’s Day.

The lyrics have a stylish feel, like a Western castle.

They’re snappy yet endlessly adorable, and the unique wordplay of weaving “nyan” into key words is charming as well.

It’s not a very famous song, but its cuteness is exactly the kind that deserves much more recognition.

Oh, glorious early summerMowamowa-P

It’s a refreshing waltz-style song, but… It’s a piece by Mowamowa-P, known for tracks like “Pollen Season,” released in 2009.

The extremely straightforward lyrics sparked a lot of discussion.

Describing those lyrics here is difficult for several reasons, so please take a look for yourself.

I’d like to live this honestly, too… That said, the tune itself is truly pleasant and will put you in a relaxed mood.

Perfect for a sunny day in May.

Operation Wake-UpYukopi

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

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!

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.

Please give this cutting-edge, Japanese-style Vocaloid track a listen! “Yomi,” a song by Vocaloid producer Atari, was released in October 2022.

It’s a bold fusion of EDM with traditional Japanese instruments, and it’s incredibly stylish.

There’s so much to enjoy—like the surging bassline, the glittering koto, and the flute swaying in the distance.

The rhythm hits hard, making you want to crank the volume way up.

The downbeat lyrics, which contrast with the energetic sound, are another big draw.
