Yumenanodeareba

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

Have you ever realized, while you were asleep, “Oh, I’m dreaming right now”? This song is exactly about that situation.

The protagonist realizes he’s dreaming about the girl he likes and thinks, “If this is a dream, then…”—this and that.

A cute daydream song about a boy in love.

Birthday

When it comes to back number’s birthday songs, most people think of “HAPPY BIRTHDAY,” but this track, “Birthday,” is a different song.

It’s the B-side of their eighth single, “Takane no Hanako-san,” released in 2013.

Among fans, it’s a highly popular number considered a masterpiece.

Like “HAPPY BIRTHDAY,” it initially seems like a birthday song, but it actually isn’t; its lyrics feel like they celebrate discovering a new self, striking a deep chord in the heart.

Mr. Perfectback number93rank/position

Mr. Perfect

Back Number’s classic “Mr.

Perfect” is striking for its nostalgic vibe.

Although it was released in 2019, the melody evokes the band’s early years.

The song as a whole is arranged with a somewhat relaxed rhythm.

Naturally, the vocal line also keeps a laid-back tempo, so there aren’t any drastic jumps in pitch.

The vocal range isn’t particularly wide for a back number song either, so even those who struggle with high notes should be able to sing it to some extent.

Consider adding it to your repertoire.

Bokuga Ima Dekirukotoo

Back number’s classic “Boku ga Ima Dekiru Koto wo” is striking for its acoustic first half.

It’s a gem where back number’s delicate lyrics and melody shine, and it’s especially popular among fans.

The song unfolds at a very slow tempo throughout.

While it does feature relatively many long notes, there aren’t any abrupt pitch jumps, so even those who aren’t confident singers should find it easy to sing.

Although songs centered on long notes are easier if you can do vibrato, the original performance doesn’t use vibrato either, so you don’t need to worry about that too much.

back number – “My Name” Music Video

I really like the way the lyrics are expressed.

Although the lyrics are from a male perspective, they don’t make women feel uncomfortable at all—in fact, it’s a song that makes you feel warm and fuzzy.

I especially liked the line “I’m yours.” I think it’s a song that soothes you no matter how many times you listen to it.

Translucent personback number96rank/position

Translucent Human / back number (cover)

This is a song included on the second single “Hanataba,” released in 2011, as well as on their major-label debut album “Superstar.” It sings of lingering feelings for a former lover and memories that won’t fade.

We all have times when we can’t forget past happiness.

That sentiment is captured in the title word, “Translucent.” If you’ve recently gone through a breakup, you might find its message especially relatable.

Liarback number97rank/position

Liar

It’s the tenth track on their 14th album, Chandelier, released on December 9, 2015, and it’s a song themed around human relationships.

It conveys a dilemma: telling lies to make life more comfortable, and wondering whether friends will reach out when it really matters.

one roomback number98rank/position

One Room

The back number classic “one room,” with its strikingly orthodox J-pop rock melody, leaves a strong impression.

Since it was released early in their career, the youthful quality of vocalist Iyori Shimizu’s voice also stands out.

The most singable aspect of this song is, above all, its chord progression.

Because it uses chords frequently heard in Japanese pop, every part makes it easy to find the pitch.

In addition, the vocal range is narrow, so even those who can’t hit high notes should be able to sing it without issue.

reunionback number99rank/position

Reunion

Released in December 2016, this song is a lavish collaboration.

Produced by Takeshi Kobayashi, it features Motohiro Hata and back number performing together, singing about emotions that sway in the city and the theme of “reunion” that arrives in fleeting moments.

The contrast between Iyori Shimizu’s and Motohiro Hata’s voices is wonderful, evoking warmth within the bittersweetness.

It was used as the CM song for Tokyo Metro’s “Find my Tokyo.” campaign starring Satomi Ishihara, so many listeners will likely recognize it.

In addition, the limited first edition B of the best album “Encore” includes a short film based on this work.

It’s a track you’ll want to listen to quietly when you wish to remember something important amid busy days.

golden hourback number100rank/position

Golden Hour

Despite its glittering title, this track stands out with a hefty rock sound and distorted guitars.

It embodies the band’s resolve to keep stepping onto the stage without settling for the status quo.

The song is included on their seventh album, “Humor,” released in January 2023.

While it doesn’t have a specific tie-in, it was written late in the album’s production and plays a key role in threading a backbone through the whole work.

Shimizu Iyori’s lyrics—confronting the struggles behind flashy success and calmly assessing where they stand now—are sure to strike listeners to the core.

It will powerfully push the backs of working adults fighting day by day and those trying to take on new challenges.

It’s a number with overwhelming intensity that makes you want to experience it live.
