Songs with titles starting with 'O' [Great for karaoke and shiritori!]

Songs with titles starting with “O” often feature unique names—like those using characters meaning “dance” or “gold,” as well as Osaka-themed songs.

They also tend to be great for getting everyone fired up when singing! I can’t think of many off the top of my head, so I want to look some up…

This is a list that might come in handy at such times: songs with titles that start with “O.” Use it when you’re wondering, “What songs start with ‘O’?” and also as a prompt for shiritori or when choosing tracks at karaoke.

Phantom C—an idol group produced by Ado—lures listeners into a mysterious storyworld that fuses a retro texture with horror elements.

Released as their 1st single in June 2024, this track was written and composed by Koharu of Charan-Po-Rantan.

Beneath its cute-sounding surface, it depicts a swirl of uneasy feelings like paranoia and surveillance.

Also included on the album “Memories of Girlhood,” it was performed again in January 2026 when they appeared with Ado for THE FIRST TAKE.

It’s a recommended song for those seeking a slightly edgy, thrilling musical experience that’s more than just “cute.”

Released in January 1999 as Every Little Thing’s 11th single, it also drew attention as the ending theme for the TV drama “Border: Criminal Psychology Investigation File.” It ranked high on the Oricon charts and has been beloved for many years.

Its medium tempo and easy-to-remember melody make it a pleasure to sing at karaoke without straining.

It’s a quintessential winter song that we especially hope people in their 40s—who spent their youth with this track—will sing!

This is a single released in January 2026 by singer-songwriter Mahato Funatsu.

The song depicts how two people who initially felt a bit out of sync gradually come to share similar catchphrases and values as time goes by.

Funatsu’s straightforward vocals resonate gently in the cold winter air.

It’s a number we especially hope happy couples will listen to—those who can laugh together as they discover the ways they’ve begun to resemble each other.
