[Adultery Songs] Forbidden Affair Tracks About Unattainable Love (61–70)
Manhattan KissTakeuchi Mariya

There are surprisingly many songs themed around forbidden love by singer-songwriter Mariya Takeuchi.
The subtle, uniquely female perspectives and emotions she portrays often feel very real and pierce the heart.
The song introduced here is Manhattan Kiss.
Released in 1992, it also served as the theme song for a film of the same name that premiered at the same time.
The lyrics read like the thoughts of a woman left alone in the hotel where she always meets her married lover.
It’s a track that makes you empathize with the protagonist’s inability to make a clean break and say goodbye.
Naniwa boatNakamori Akina

Released by Tokiko Kato in 1984, this song was covered and released in 1987 as Akina Nakamori’s 19th single, becoming a major hit.
It’s said that Tokiko Kato herself earnestly wished for Akina Nakamori to sing it, which led to the song being offered to her.
Cover versions were subsequently released by prominent artists such as Kaori Momoi, Tomomi Kahala, and Fuyumi Sakamoto, cementing its place as a classic of the Showa era.
My lover has left, and I’ve lost everything, yet the city remains unchanged.
Perhaps it’s important not to put on a brave face, and to allow ourselves to fully grieve a heartbreak.
MELROSE ~A Promise Not to Love~EXILE ATSUSHI

“MELROSE ~A Promise Not to Love~” was released in 2012 as EXILE ATSUSHI’s third single.
Chosen as the theme song for the ‘Reveur Moist & Gloss’ commercial, it tells the story of two people who promised not to fall in love yet end up drawn to each other—a song about a mature, adult romance.
A love I can tell no one abouterica

This love song is said to have been made for a fan with an unrequited crush.
Because it was based on real feelings, it has a super realistic vibe.
They fell in love, but the other person already has a partner, and there’s no one they can talk to.
The protagonist regrets having a forbidden love and sinks into terrible self-loathing.
Still, keeping quiet forever is too painful, so they decide to take a step forward.
No matter what kind of love it is, holding it all inside is hard, isn’t it?
The Last RainYasushi Nakanishi

It’s a song about an affair told from a man’s perspective.
The one featured here is Yasushi Nakanishi’s “Saigo no Ame,” released in 1992.
Even nearly 30 years after its release, it’s still a classic covered by many.
The protagonist is told goodbye by the person he loves, and his burning feelings for her really hit you in the chest.
Maybe the mistress is saying goodbye so she can return to her husband, or maybe the wife has chosen her lover and is seeking a divorce—there are many possible situations.
What’s common to all of them, though, is a passionate love so strong that he doesn’t want to let her go.
FortuneHY

Speaking of HY, their refreshing songs that evoke nature are popular, but their ballads that depict slightly complicated relationships are also compelling, aren’t they? Like in this song, even relationships where the two loved each other at the beginning can reach a point where, for various reasons, they can’t honestly say “I love you” anymore.
“Fortune,” included on HY’s 2014 release HY LOVERS BEST, expresses the feeling of pretending—of being unable to genuinely say you truly like the other person now, unlike how you felt before.
eternityZARD

ZARD’s 22nd single, Eien (Eternal).
It was used as the theme song for the drama Shitsurakuen (Lost Paradise), which deals with the subject of an extramarital affair.
I’m sure the lyrics, which seem to express feelings kept deep in one’s heart, will resonate with you.
Sakai’s gentle vocals, which somehow envelop the loneliness one must bear alone, are sure to be soothing.
In the sense of wanting to end it but being unable to, an affair is a love with no end.
Try listening to Eien while reflecting on such a love you can’t tell anyone about.
