Aimer Popular Song Rankings [2026]

Believe Be:leaveAimer64rank/position

Aimer 『Believe Be:leave』

The song “Believe Be:leave,” included on the 3rd album DAWN, was used as the ending theme for the music program ONCHIKA.

Its airy, transparent ensemble really lingers in the ears.

Although the key is a bit high, the restrained vocal delivery makes pitch control easier, and the melody has relatively gentle dynamics, so it should be manageable even for those who aren’t confident singers.

It’s a soft pop tune that will draw everyone in when sung at karaoke.

Deep downAimer65rank/position

Aimer “Deep down” MUSIC VIDEO (TV Anime “Chainsaw Man” Ending Theme)

Set against a heavy soundscape that captures the sensation of sinking into darkness, this track was featured as the ending theme for Episode 9 of Chainsaw Man.

Its deep introspection, which seems to symbolize the story’s serious turn, is especially compelling.

The lyrics were written by Aimer herself under the name aimerrhythm, with composition by Kazuma Nagasawa and arrangement by Kenji Tamai and Rui Momota.

Released in December 2022 as the title track of the mini-album Deep down, it blends a dreamy arrangement of strings and synthesizers with her husky, resonant vocals that truly strike a chord.

It’s a song that speaks to the depths of your emotions—one to listen to when you want to confront life and death, and the conflicts within.

March of TimeAimer66rank/position

Aimer 『March of Time』

It was featured in a JAL commercial.

It’s a perfect song for a commercial that portrays the bittersweet love story of a boy and girl who become separated after graduation.

It’s a “sakura song” that stays close to the heart of someone taking a new step forward, giving them strength and a gentle push.

Aimer「Ref:rain -3 nuits ver.-」Music Video

Aimer is a female singer-songwriter loved by a wide range of generations, and she’s certainly a popular artist among teenage girls as well.

Among her works, the one I especially recommend is “Ref:rain -3 nuits ver.-.” This piece is arranged as a gentle ballad, so there aren’t any abrupt jumps in pitch, making the overall vocal line easy to sing.

While it does feature many high notes, they aren’t extremely high, so be sure to give it a listen.

Someone, the sea.Aimer70rank/position

Aimer 'Someone, the Sea.' MUSIC VIDEO (FULL ver.)

This song, Dareka, Umi o (Someone, the Sea), was used as the ending theme for the anime Terror in Resonance.

The anime tells the story of boys whose future was unjustly taken from them as they strike back at society, and from this track you can feel the protagonists’ emotions depicted in the show—anger, despair, and resignation.

More than the lyrics themselves, I especially recommend the atmosphere of the song, which seems to accept your sinking feelings just as they are.

It’s sung by Aimer, a popular singer known for her distinctive voice.
