A song themed around letters. A popular letter song.
Compared to the past, we write and receive letters far less often nowadays.
Still, letters have their own charm, and I think they’re a wonderful way to convey your feelings.
Precisely because of the times we live in, there may be many things that come across better in a letter.
This time, I’ll be introducing songs with the theme of “letters.”
There are many kinds of letters—thank-you notes, love letters, letters to your future self—so there are all sorts of “letter songs.”
Just hearing the word “letter” makes it feel like something filled with heartfelt emotions, doesn’t it?
Since there are letter songs for many different situations, I hope you’ll find a favorite.

From an intro that bursts with the sweet tang of youth and sets your heart dancing, this is the quintessential popular number by moon drop.

The track is included on their first full-length album, “Kono Tenohira ga Mada Kimi o Oboete Iru,” released in January 2022.
It was also used as a CM song for Honda Cars, broadcast across seven prefectures in the Chubu region, including Aichi and Mie, so plenty of people have likely heard its refreshing melody on TV.
This song sets indecisive feelings toward someone you love and a premonition of love’s end to an easygoing beat.
It’s perfect not only for students swaying with tender crushes, but also for anyone who wants to bask in bittersweet memories from the past.
Love letterShirahane Reiko
This work is a cover of a punk rock classic, rendered with a delicacy unique to a female vocalist.
Unlike the raw, unbridled passion of the original, the soft, translucent voice gently wraps around the earnest wishes entrusted to a letter.
Written in the first person as “I,” the words addressed to a lover who is no longer by one’s side blend overflowing lingering attachment with deep affection, tightening the chest with every listen.
Released as a single in February 2005, it also became familiar as the ending theme for the TV Asahi drama “Tokumei Kakarichō Tadano Hitoshi.” Reiko Shiraha’s vocals added a profound sense of wistfulness to the drama’s world.
When you’re carrying feelings that won’t reach their destination, or when you want to quietly shed tears alone at night, this song will gently stay by your heart.

The imagery—twilight at the station and scenes along the tracks—feels so vivid it tightens the listener’s chest with a poignant ache.
The song was included on the album UNDERWEAR, released in October 1996, and was later used as the theme for NTT East’s corporate commercial “Mother,” featuring Yui Aragaki.
This piece rekindles the unspoken kindness we couldn’t put into words and the bittersweet memories of youth.
It’s a song to savor, especially for those who’ve experienced a springtime parting or who carry unspoken feelings in their hearts.
Love letterHey! Say! JUMP
This is a ballad that captures the frustration of being unable to take that first step in love, alongside the pure feelings you hold for someone.
Its structure—passing the vocals along over delicate piano and strings—seems to carefully trace the subtle shifts of a wavering heart.
Many listeners will likely feel a tightening in their chest at the image of someone entrusting their overflowing feelings to a letter, lacking the courage to speak directly.
It’s the coupling track included on the standard edition of the single “encore,” released in May 2025.
While the title track drew attention as a TV drama theme, this song quietly won fans over as a hidden gem.
It’s a piece that stays close on nights when you want to keep thinking of someone in silence.
For anyone experiencing a one-sided love and finding it hard to be honest, this is a work you should definitely hear.

It’s included on their first album, Parade, released in March 2024, and it moved audiences when performed on their solo tour.
It’s a track that gently stays by your side not only when you want to express your honest feelings to a partner, but also on nights when you want to be kind to yourself.
That feeling of lightness in your heart after the song ends is truly wonderful, isn’t it?
