This is a song that captures a woman’s complex feelings: while she speaks of her current partner’s kindness, she can’t help but recall the comfort of the days spent with her ex.
It’s a track released in August 2018 by the pop band wacci, known for crafting music that sits close to everyday life, and it’s also included on the album “Gunjou Refrain.” The lyrics, written by vocalist Yohei Hashiguchi based on a female friend’s story, contrast the perfection of a new partner with lingering feelings for an ex, tightening the listener’s chest.
In June 2021, it surpassed 100 million streams, cementing its status as a long‑loved classic.
After a springtime parting, when forcing yourself to look ahead leaves your heart tired, this song might gently stay by your side.
If you laugh at the skywacci2rank/position
Let me introduce a motivational song packed with a powerful message: when you feel like crying, look up at the sky and smile.
This track by the five-member band wacci was released digitally in July 2018 and was later included on their album “Gunjo Refrain,” released in November of the same year.
While hard work doesn’t always lead directly to results, the warm perspective that the days you’ve built up are never wasted gently encourages listeners.
Starting in August 2019, it was also selected as the support song for the “Japan Tsunagaru Project” segment on the TV program Mezamashi TV, moving many people alongside the images of those doing their best.
It’s a perfect recommendation for graduation season—an uplifting song that stands by students retiring from club activities and anyone setting out on a new path.
It’s love, right?wacci3rank/position
I’ve been posting songs with the theme of “men with low voices,” and many of my students are “men with low voices” too! One of them has been practicing wacci’s “Koidaro.” In this song, the chorus jumps up in range to F#4, but the lowest note is a pretty low B2, which actually appears multiple times throughout.
How about first making sure you can firmly produce those easier low notes, and then try tackling the high notes with some momentum? Of course, it’s totally fine to start with falsetto instead of chest voice! If you keep singing, there will definitely be a point where it clicks, so I think it’s worth giving it a go even if it feels “a bit high.” Just don’t push yourself!
It’s okaywacci4rank/position
A warm, encouraging song that stands by you, who have thrown yourself wholeheartedly into your club activities every day.
Released as a single in August 2015, it was written as the theme song for the drama “37.5°C no Namida.” The down-to-earth words and melodies woven by vocalist Yohei Hashiguchi bring a sense of comfort to listeners.
Some of you may be feeling a bit anxious as you reach the major milestone of retirement and face the days ahead.
Listening to this song will help you recognize and appreciate the effort you’ve put in up to now.
Emotionwacci5rank/position
A heartwarming love song by wacci that delicately portrays the many emotions of romance.
It’s striking how everyday words like “good morning” and “good night,” exchanged in daily life, gradually take on a special meaning shared only by the two of them.
Included on the album “Kanjō Hyakkei,” it was released in August 2017.
The gentle melody and warm vocals together tenderly envelop the journey from the beginning of love to a deep bond.
It’s a song you’ll want to listen to when you and your partner, who sometimes clash, want to reflect on each other’s feelings.
By recalling how you felt at the very start of your relationship, it can be the spark you need to express yourself honestly.

This is a heartbreak song overflowing with poignancy, capturing the emotional turmoil of trying to sever lingering feelings for an ex.
Featured on wacci’s 2019 album Empathy, the track stands out for its lyrics written from a woman’s perspective.
Though she still has feelings, the protagonist’s struggle to choose a clean break in order to move forward is deeply affecting.
Positioned as a side story to “Betsu no Hito no Kanojo ni Natta yo,” a one-take recording was also released in 2020.
It’s a must-listen for anyone who’s gone from mutual love to one-sided, or who wants to move on but can’t quite bring themselves to do it.

Interestingly, it drew attention when Miho Takagi named it her “victory song” to listen to before competitions at the PyeongChang 2018 Winter Olympics, which also led to a live performance on the TV program “Sukkiri.” It’s a perfect song for those striving toward their dreams or for teammates pushing each other to improve, such as in school clubs.
