MiracleGReeeeN

GReeeeN – Kiseki

Speaking of summer, youth comes to mind, and this song—now a staple at the Summer Koshien—is my recommendation.

Thanks to the drama ROOKIES, it’s often associated with baseball, but the music video is the very essence of youth.

It reminds you of the warmth of your family and the people around you—things that can be hard to see when you’re a student.

It’s the perfect song for your last summer as a student.

A Little Love SongMONGOL800

MONGOL800 / A Small Love Song

This song is a summertime staple and a classic love song as well.

It captures the carefree vibe of summer and the joy of meeting someone special, while amplifying the longing to see them.

It gives you a gentle push to express your feelings and to take action.

Summer SongYUI

YUI　『Summer Song-short ver.-』

This song by singer-songwriter YUI straightforwardly voices episodes about summer and the emotions that come with them.

Positioned as a sequel to the single “Laugh away,” released the same year, it contrasts with its predecessor—which is told from a boy’s perspective—by being written from a girl’s point of view.

The sound is characterized by acoustic guitar at its core, leaving a strong impression with a freshness like a summer blue sky, tinged with a hint of wistfulness.

It portrays the moment when, with a summer full of events on the horizon, the narrator resolves to express her feelings, conveying the bittersweet flavor of youth.

Ayumi Hamasaki / Greatful days

This is a classic summer song included on Ayumi Hamasaki’s 29th single “&,” by the Heisei-era diva who dominated Japan’s music scene from the 1990s through the 2000s.

The lyrics express the joy of the long-awaited season’s arrival and gratitude for the everyday moments that are most precious, capturing the fleeting sparkle of summer with evocative imagery.

Its arrangement—light beats intertwined with bright synths—conjures vivid summer scenes.

Released in July 2003, the track was used as the theme song for Fuji TV’s music program “ayu ready?” and became widely loved as a summer youth anthem.

It’s a perfect blend of freshness and bittersweet emotion, ideal for drives or time spent by the sea.

Dragon Ash｢Summer Tribe｣

This song, which radiates summer energy, was released as a single in July 2000.

As the eighth single from the nu-metal/mixture rock band Dragon Ash, it features powerful beats and an airy, floating track.

With tightly woven rhymes that paint vivid summer scenes, it’s a party tune perfectly suited for a midsummer afternoon.

The Story You Don’t Knowsupercell

The Story You Don’t Know – supercell

Covered countless times by various idol groups like Idol Renaissance and ClariS, this is the kind of song that makes you think there are probably fewer people who haven’t sung it than have: “Kimi no Shiranai Monogatari.” Recently, Kana Hanazawa—now hugely popular for Demon Slayer—also released a cover.

From the no-intro start, to the spoken-monologue-style lyrics, the structure, the way the chorus soars—every element is flawless, a true monument of Japanese pop.

The nostalgia-soaked lyrics are exquisite too, making you want to gaze up at the night sky.

It’s a song that brings back so many memories—perfect for summer.
