Kimiga Door O Shimeta Ato

The back number classic “Kimi ga Doa wo Shimeta Ato,” where emotive lyrics truly shine.

Sung from a male perspective about the feelings right after a breakup, it’s characterized by its deeply heartrending lyrics.

Interestingly, despite its emotional words, the song features a surprisingly plain and understated vocal line.

Because of that, it’s easy to sing for those who struggle with ballad-like delivery that demands dramatic dynamics.

The vocal range is narrow and there are few long sustained notes, so even singers with lower or huskier voices should definitely give it a try.

back number – ARTIST (full)

Included on buck number’s 17th single, “Mabataki,” released on December 20, 2017.

When you think of buck number, you might picture songs that express natural, honest emotions, but this track has a sharp, up-tempo edge.

Listening to buck number like this is really great, too.

Highly recommended.

Emeraldback number73rank/position

Emerald

It’s the ending theme song for TBS’s Sunday drama “Dangerous Venus,” available for streaming since October 2020.

As of the time of writing, no CD release schedule has been announced.

It’s a medium-tempo rock song with a slightly wistful melody, and Shimizu Iyori’s vocals—skillfully making extensive use of falsetto—are arranged to further highlight the song’s appeal.

The way falsetto (head voice) is used offers many points that male vocalists in bands can learn from, so be sure to pay attention to the switching and differentiation of vocal registers as you listen.

march

While back number has many unrequited-love and heartbreak songs, they do have some mutual-love tracks as well.

Among them, the one I particularly recommend for its ease of singing is March.

Its lyrics capture the various feelings that arise while looking at a lover sitting in the passenger seat, and the melody is striking—full of a driving sense of speed that evokes a road trip, yet tinged with a chill vibe.

The vocal line in this song is very understated, repeating similar phrases over and over, so the level of difficulty is quite low.

back number - Even if I someday forget

A three-piece rock band, back number, boasts immense popularity among the younger generation for their heartrending lyrics that vividly paint scenes and songs steeped in melancholy.

This track, included on their first album “Atonomatsuri” (Ato no Matsuri), is widely known among fans as a masterpiece despite never being released as a single and having no music video.

Its lyrical melody and chord progression set to a relaxed shuffle beat lend even greater poignancy to the heartbreak-themed lyrics.

It’s a hidden gem from back number, with an exceptional atmosphere that makes you feel the chill of winter’s wind.

back number – Siren (full)

While I found myself growing more at ease the more I fell in love and got to know my partner, she, in contrast, lost interest the more she got to know me.

This song focuses on the differences between men’s and women’s romantic feelings.

As my love deepened, it inversely cooled for her, leaving my feelings with nowhere to go.

Paradeback number77rank/position

Parade

Parade, a signature hit by back number, exudes an energetic vibe.

This piece features a chord progression similar to one of back number’s biggest hits, Watagashi, and unfolds with melodies and vocal lines that feel familiar to Japanese listeners.

Above all, its most singable point is undoubtedly the narrow vocal range.

Since the vocal line develops entirely within the mid-range, it doesn’t depend on the singer’s range, making it easy for anyone to sing without difficulty.

A song by back number that opens the album “Humor,” released in January 2023.

It gently portrays the hidden feelings of two people in love, accompanied by emotional tones.

The lyrics, where bittersweetness and tenderness intertwine, are moving, drawing you into back number’s characteristically delicate emotional expression.

The words crafted by Iyori Shimizu conjure vivid scenes as if from a movie.

It’s perfect not only for those newly in love, but also for moments when you want to look back on memories with someone dear.

A track that leaves you wrapped in a warm afterglow that seeps into the heart.

A Windy Dayback number79rank/position

A Windy Day

This is a spring tearjerker that makes you empathize so deeply you could cry—the chorus is so unbearably poignant, as it recalls past memories and everyday moments with a lover, and keeps blaming oneself for wallowing in sadness.

The ending feels like the path has already been set somewhere, and Back Number’s songs never fail to capture my heart.

MOTTOback number80rank/position

Motto

When it comes to back number, known for producing numerous love songs, it’s all about bittersweet unrequited love songs and breakup songs! In this track, the lyrics depict someone so desperate to be understood that their desire for the other person could be called obsessive love, to the point they can’t let go.

Such straightforward feelings can come off as heavy and, in some cases, might even get labeled as “mentally unstable.” Featured on the album “Love Story,” released in March 2014, this song might help clear your head when your partner’s behavior seems a little suspicious…

If you’ve experienced love, there are probably many parts you’ll relate to.
