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.

Only YouMAZZEL

MAZZEL / Only You -Music Video-
Only YouMAZZEL

Released in November 2025, “Only You” was selected as the ending theme for the Nippon TV drama Therapy Game.

Member NAOYA appears in the drama, closely linking the work and the music.

It’s a mid-tempo ballad that carefully portrays the anxiety that grows when you can’t see the one you love, along with unwavering, single-hearted devotion.

The contrast between vocals that retain delicate breaths and the rich harmonies vividly expresses the ebb and flow of emotion.

It’s a song that will leave your chest tight with moving emotion when you listen.

I was totally shocked.ROF-MAO

Aired as one of NHK’s “Minna no Uta” songs for October–November 2025, this track is a bright, poppy number that’s quintessentially ROF-MAO.

It carries a message of laughing off everyday surprises and confusion in a positive way, with catchy wordplay and back-and-forth vocals that really stick in your head.

Written, composed, and arranged by Shingo Yamazaki, it features an uptempo sound and easy-to-hum phrases.

ROF-MAO is a powerhouse unit that won the Best New Artist Award at the Japan Record Awards in 2024 and topped the Oricon chart with their album “Overflow.” Two versions were produced—an NHK anime version and an artist MV—making it a work that reaches a broad audience.

Even if you’re not a VTuber fan, the upbeat pop vibe is easy to get into, and it’s sure to create a sense of unity if everyone sings it together at a year-end party!

The Never-Ending SongTHE BLUE HEARTS

One of the signature tracks from THE BLUE HEARTS’ debut album, THE BLUE HEARTS, which left a major mark on Japan’s punk rock scene.

It’s an anthem that delivers a powerful declaration to keep singing for oneself and for kindred spirits, set to a straightforward and catchy melody.

In 2002 it was used as an insert song in the Fuji TV drama ‘Hito ni Yasashiku’ (Be Nice to People), and in 2011 it was featured in a JRA commercial.

The repeated phrase in the chorus is structured to make you hum along naturally, creating a sense of unity that transcends generations.

It’s the perfect song for linking arms and getting fired up together at year-end or New Year parties.

Dear SantaKoresawa

Koresawa “Onegai Santa Claus” [Lyric Video]
Dear SantaKoresawa

This song, which poignantly captures the lonely feelings of reflecting by oneself on a winter night, is a beloved Christmas classic that Koresawa has been singing since her indie days.

It was released digitally in November 2023, fulfilling fans’ long-held wish for an official recording.

Set to a gentle band sound centered on piano and guitar, the lyrics—about finding the courage to let go of the past and the resolve to choose what truly matters—resonate deeply.

With its medium tempo and easy-to-sing melody, its warm tone feels like a quiet companion to the listener.

Perfect for those spending Christmas alone or for anyone who wants to sing softly while looking back on the year.

It also makes a great choice to play quietly toward the end of a year-end party.

No reply yet, Kana? 💦 An old-man-text style 😁❗️ / Amai (Raincoat)
No reply yet? Uncle-style text!Yoshimoto ojisan

It’s a call-and-response-style Vocaloid tune that turns any venue into a whirlwind of laughter in an instant! The runaway “old-man texting” syntax and the recipient’s cool comebacks unfold like a dialogue play, and the track’s uniquely breezy four-on-the-floor beat keeps the clapping nonstop.

The theme humorously transforms a slightly bothersome messaging culture, landing the wavering feelings between embarrassment and irritation squarely in laughter.

Yoshimoto Ojisan’s keen eye shines here.

The music video drops on May 31, 2025, featuring the voice of Amagasa.

It topped Billboard JAPAN’s “Niconico VOCALOID SONGS TOP20” for three consecutive weeks in June.

The karaoke version, complete with official footage on JOYSOUND, is also a hot topic.

For year-end parties, pair up, split the roles, and go all-in with the cue-timed hip-sway choreography—guaranteed to kill!

Only One StoryZEROBASEONE

[Official] Pokémon Anime “Rayquaza Rising” Opening Theme: “Only One Story”
Only One StoryZEROBASEONE

It’s the opening theme song for the TV anime Pokémon.

The performers are ZEROBASEONE, a group formed through an audition program.

The upbeat, powerful message in the lyrics seems to mirror the protagonists as they meet new companions and step into uncharted worlds, doesn’t it? It truly feels like the beginning of an adventure where they weave a story all their own—something that gets your heart racing.

It also ties in with the group’s journey of “starting from zero,” making it all the more stirring.

This track, released in October 2024, marks their first-ever anime tie-in.

It will also be included on their Japanese debut EP, “Prezent,” set for release in January 2025.

It’s a song with a comforting sound that feels like a push forward when you’re starting a new challenge.

Until the day I can no longer rememberback number

back number – Until the Day It Becomes Unrememberable (full)
Until the day I can no longer rememberback number

A poignant ballad by back number that quietly sings of lingering feelings and a sense of loss for a former lover.

Released in October 2011 as their third single, the song is also included on the album “Superstar,” which came out the same month.

The lyrics portray the emptiness of days that keep going even after losing the most important person in the world, and the deep bond in which the two formed halves of each other.

Fear of memories of the other fading intertwines with the resignation that they will eventually be forgotten, and the realization that the time spent with the person was part of oneself wells up with aching tenderness.

A song that offers comfort to anyone who has lost someone dear.
