Aimer’s Most Popular Karaoke Songs Ranking [2025] (1–10)
Song of FlowersAimer1rank/position
This is Aimer’s 13th single overall, released on October 11, 2017.
By the way, it was released as a triple A-side together with “ONE” and “Rokutousei no Yoru Magic Blue ver.” It’s a dramatic number that lets you fully enjoy Aimer’s deeply resonant, captivating voice.
If you sing this at karaoke and can give the song the same kind of “depth” as the original, that might be a special privilege for low-voiced women.
The arrangement also makes lavish use of symphonic sounds, resulting in a very dramatic track.
If you end up mumbling, you’ll lose the song’s appeal, so try directing the sound toward your lower jaw inside your mouth, resonating firmly in the chest cavity, and mastering your chest voice as you sing.
I’m sure you’ll be able to deliver a rich, deep vocal!
Unrequited loveAimer2rank/position
“Kataomoi” has a distinctive rhythm and leans more toward “speaking” than “singing,” but this song was often sung by one of my voice-training students who wasn’t confident in singing and didn’t have a very wide range.
If you’re going to sing it, you’ll probably struggle with the rhythm first, so practice by listening to the song over and over.
Aside from the chorus, you don’t need to worry too much about pitch at the beginning.
If the rhythm doesn’t lock in first, it’ll feel off when you sing, so pay attention to where the phrases are cut and when each entry comes in, and maybe start with humming.
Humming will help you carry that same feeling into light singing, letting the sound resonate between your eyebrows without tension.
Once you’re used to it, keep that resonance in the brow area and shift into your singing voice.
If you can keep resonating in the same spot while you sing, you’ll capture a really nice vibe!
bow knotAimer3rank/position
A perfect song for weddings and receptions has arrived.
It’s a piece where Aimer’s vocals and RADWIMPS’ Yojiro Noda’s production blend beautifully.
Using the metaphor of a “butterfly knot,” it portrays love and human relationships, expressing the strength of the couple’s bond and the deepening of their affection.
Released in August 2016, the music video was directed by the renowned filmmaker Shunji Iwai.
It’s recommended for those who want to sing with heartfelt congratulations for the bride and groom.
With its warm lyrics and beautiful melody, it’s sure to lift the atmosphere of the venue.
Zankyo SankaAimer4rank/position
Released in January 2022 as Aimer’s 20th single, this song was selected as the opening theme for the popular anime Demon Slayer: Kimetsu no Yaiba – Entertainment District Arc.
It topped the Billboard Japan Hot 100 for nine consecutive weeks, surpassed 200 million streams, and received a Special Award at the Japan Record Awards.
Masahiro Tobinai’s bold arrangement features resplendent brass and strings that brilliantly capture both the opulence of the red-light district and the tension of battle.
The lyrics, imbued with a powerful resolve to overcome past pain and resound into the future, embody the very determination of characters who confront their fate.
Performed even in cheering scenes at Koshien, it’s a song cherished not only by anime fans but also by many listeners running through their youth.
lovesicknessAimer5rank/position
This song beautifully captures the bittersweetness of love.
Aimer’s rich, resonant voice conveys the pain and struggles of romance without leaving anything unsaid.
Included on the album “Sun Dance,” released in April 2019, it was also chosen as the theme song for an AbemaTV dating reality show.
It’s recommended for those who struggle with unspoken feelings or the sense of distance between themselves and someone special.
If you sing it at karaoke, it’s sure to strike a chord with the opposite sex.
They might even see you as someone who understands what it’s like to wrestle with love.
Black BirdAimer6rank/position
Released in 2018, it was also the theme song for the film Kasane.
I’ve been focusing on songs with relatively simple, easy-to-understand, and easy-to-remember melodies, but in that sense, this song might not quite fit the bill.
At first listen, it sounds like a song with a fairly complex melody, doesn’t it? Still, don’t be intimidated by that.
Some parts may seem difficult to sing because of Aimer’s distinctive vocal style, but the vocal range used isn’t that wide.
If you listen closely, learn the melody, and sing it, I believe it will be a song that many people find easy to perform.
On nights when I'm too lonely to sleepAimer7rank/position
The second single, “On Nights So Lonely I Can’t Sleep,” was released as a double A-side with “Re:pray” as a conceptual single.
The song, which secured multiple tie-ins including serving as the ending theme for the music program “MUJack,” is notable for its richly layered ensemble of piano and strings.
Its narrow vocal range and restrained delivery make it relatively easy to sing, but be careful with the leaps in pitch during the chorus—they can cause you to slip off the notes and make it hard to return to the original melody.
It’s a sentimental ballad number that you’ll want to sing while imagining the emotions conveyed by its heartrending lyrics.
