FallSuperfly

In contrast to the song that quietly portrays a growing yearning for a man, this track, “Fall,” is very provocative.
It lures a man into an affair and mocks him with lines like “You’re not even serious.” It may seem cruel, but love and hate are two sides of the same coin.
Perhaps it’s precisely because she loves him that she says, “Go to hell.” This song was used as the theme for the drama “Anata ni wa Kaeru Ie ga Aru” (You Have a Home to Return To).
I want to be loved.Mioyamazaki

A song whose vanishingly fragile, heartrending vocals tighten your chest.
Even knowing it’s almost impossible to stay together, the woman’s feelings—her wish to see the future she envisions come true—are depicted in delicate words.
The fact that she truly wants to be together but can’t express it honestly reflects her awareness that she’s hurting someone and that the relationship shouldn’t continue any further.
It’s a song that makes you think deeply about whether happiness can await a love that comes together while hurting many people.
So it wasn’t me, huh.riria.

This song, Riria.’s “It Wasn’t Me, Was It.”, pierces the heart with the feelings of the so-called ‘second woman’ seen from a woman’s perspective.
When you’re having an affair or a love you can’t tell anyone about, you probably end up bottling up a lot of emotions inside, don’t you? In this song too, there are lyrics about keeping quiet and enduring—wanting to continue the relationship—even though she sensed his actions and attitude and kind of knew what was going on.
I’m sure many people will relate.
You can also feel that, even knowing the truth, she just couldn’t help loving him so much.
Love SpiritsChatmonchy

Chatmonchy’s “Renai Spirits” is their second single, released in 2006.
Although it’s an early work, it isn’t a straightforward love song or a sad breakup song; it portrays someone who shows one-sided affection, trying to steal away a person who’s already in a relationship.
In the real world, that kind of thing can lead to drama later, so I think many people, no matter how much they like someone, give up once they realize that person already has a partner.
But the protagonist of this song has a darker side, seeming to continually spill over with a kind of madness, wanting the person to look only at her.
Crossing Amagi PassIshikawa Sayuri

“Amagi-goe” is a song released by Sayuri Ishikawa in 1986, which won the Gold Prize at the 28th Japan Record Awards.
Its theme—two people somehow managing to cross the difficult Amagi Pass—can be interpreted as a positive, strong song about an extramarital affair.
Beyond being an affair-themed song, it is also renowned as a classic enka piece and is beloved in karaoke.
The Amagi route is said to be located on the Izu Peninsula.
I didn’t want to know, if it meant losing it.atarayo

A song where aching sadness and faint hope intersect.
Carried by Atarayo’s vocals, it gently portrays the feelings of those tormented by unrequited love.
Even after learning the truth of a lie, the growing fear of losing the one you love is striking.
Released in January 2022 as an advance single from the album “In the Polar Night, the Moon Remains Silent,” this piece was born from a collaboration with the “Junwaidan” project, drawing on an episode selected from over 10,000 submissions.
It’s a song that stands beside anyone who wants to look forward while carrying the pain of heartbreak—recommended for moments when you want to face the complex emotions deep within your heart.
AitaiKato Miria

When it comes to timeless songs you want to listen to when you’re going through heartbreak, you can’t leave out “Aitai.” It’s a track from Miliyah Kato’s 2009 album “Ring,” and it was used as an insert song in the 2010 film “Akunin” (Villain).
Many women have likely been moved to tears by the lyrics, which earnestly express a woman’s single-minded devotion.
“Even if you’re not kind to me, even if you have someone else, I still love you…”—that kind of sorrow tightens your chest.
It’s a highly recommended song for those times when you want to cry your heart out because you can’t see the person you love.
