TwinkleStartChou Tokimeki♡Sendenbu
Cho Tokimeki♡Sendenbu’s “Twinkle Start” is set for release in 2025, and it feels like a song that gently speaks of hope for the future.
Its relaxed tempo is striking, and it evokes an image of earnestly reaching out to each listener’s heart.
The lyrics, which depict how one wants to spend time with someone special, are also memorable, conveying a sense of savoring happiness.
The song is featured in a Pokecolo Twin commercial starring group members Hiyori Sakai and Aki Sugata.
It expresses the excitement of the moment when the two’s story begins.
Campus mode!!Hatsuboshi Gakuen
“Campus mode!!” is a full-group song from Hatsuboshi Academy, a sparkling cheer anthem with “youth” as its theme! The lyrics and tempo are super energetic, making it perfect for teenage girls! Since multiple people sing the track, it might be tricky to perform solo, but if you have friends who like Hatsuboshi Academy, splitting parts and singing together would definitely be a blast! The tempo is a bit fast, and for the A and B sections, try singing as if you’re having an excited conversation—you’ll naturally get a bright tone.
For the chorus, crank the energy even higher and project your voice as if you’re reaching far; it’ll carry better, feel more idol-like, and be even more fun to sing! For the fast lines, it’s fine to enunciate each word clearly.
The earnestness will become a charm of the performance, so try singing as if you’ve become an idol yourself!
That is a fairy.Boku ga mitakatta aozora
Debuting in 2023 and winning the Best New Artist Award at the Japan Record Awards in just one year, Boku ga Mitakatta Aozora are set to release their 7th single in December 2025.
The title track is a classic winter first-love song with lyrics by Yasushi Akimoto and music by Daisuke Shirai.
It tells a poignant story of a boy who is captivated by a girl he glimpses by chance on a train platform, and, seeing her as delicate like a fairy, keeps searching for her every morning.
Vivid scenes—winter uniforms, scarves, and crowded trains—tug at the heart, and it’s impossible not to empathize with the protagonist, who senses the love may never be fulfilled yet still engraves the feeling of “I truly fell in love.” The music video, featuring Ami Kanazawa in the center playing a transfer student, has drawn attention for its direction that shifts between reality and imagination.
Highly recommended for anyone who wants to revisit a softly bittersweet page of youth.
Getting hurt is what youth is about.STU48
STU48 is an idol group based in the seven prefectures of the Seto Inland Sea region.
Kizutsuku Koto ga Seishun da (Getting Hurt Is What Youth Is About) was released as their 12th single in August 2025.
Its message—that getting hurt is never meaningless and that people grow through pain—will likely resonate deeply not only with those in the midst of their youth but also with adults who have already gone through it.
The refreshing sound perfectly matches the lyrics, too.
With translucent vocals and a beautiful melody that lingers in your ears, it’s an emotional pop tune.
It’s the cutest ever!Chou Tokimeki♡Sendenbu
This work delivers a story of self-affirmation born from heartbreak, sung over a poppy sound that’s quintessentially Japanese idol music.
Written and composed by Koresawa, the song stands out for the protagonist’s uplifting declaration—after being dumped—of “I’ve become cuter.” Together with its catchy choreography, it surpassed 1.2 billion views on TikTok and took the top spot in DAM’s annual girls’ group karaoke ranking.
It’s a must-listen when you’re feeling down from a breakup or when you want to be reborn as a new you.
