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.

“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!

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.

17 minutesNogizaka 46

A song by the 5th generation members included on the 31st single “Koko ni wa Nai Mono,” released in December 2022.

It’s a sweet-and-sour youth pop tune that sings about the happiness of riding the same bus as the person you like for “just 17 minutes.” The contrast between the sparkling sound and the fresh vocals, together with the bittersweet story of a protagonist in love with someone whose name they don’t even know, makes your heart skip a beat.

The “clock dance” showcased in the music video and the staging where stalled time is set in motion by gears filled with their dreams perfectly embody these girls who carry the group’s future.

If you listen during everyday moments—on your way to school, for example—the world might just start to shine.

A rush of youthful pop with strikingly cool, emotional word choices.

Featured on the 39th single “Same numbers,” released in July 2025, this track is performed by Nogizaka46’s 6th generation.

Even as it repeats fundamental questions, it ultimately takes off with the attitude that “there’s no meaning anyway.” The lyrics vividly capture that unstoppable impulse unique to youth, powerfully shaking the listener’s heart.

Watching the members sprint across the field feels like a coming-of-age film come to life.

It’s a song that gives you an extra push when you’re going all out toward your goal.
