Written as the theme song for the film “How,” this piece is an impressionistic number distinguished by a gentle, piano-centered ensemble and a melody line that resonates with the heart.
Its lyrics, which sing of bonds with an irreplaceable presence—someone with whom, even after a petty quarrel, you can laugh together again the next day—are sure to kindle a warm light in the listener’s heart.
Released in August 2022 and later included on the album “Rockin’ Beats,” the song also intriguingly ties in with the film’s world, as seen in the music video’s use of dog photos collected from across the country.
Graduation Song ~Let Me Say Thank You Over and Over~GReeeeN

I wish I could stay like this forever, but I have to set off…
This is a message song that sings of the bittersweet feelings and gratitude right before graduation.
Created by GReeeeN, it’s the coupling track to the single “Aisubeki Ashita, Isshun to Isshō o,” released in March 2014, and it’s also included on the best-of album “C, D desu to!?”.
It was featured in an AOKI commercial, cheering on the first steps into a new chapter of life.
Carried by a refreshing, warm melody, the straightforward lyrics make you want to say “thank you” over and over again, striking straight to the heart.
The harmony woven by the four voices is moving, making it a perfect song for a slideshow of memories with friends or an Instagram story to express your gratitude.
Sky of TearsGReeeeN

A song that teaches us, in this season of farewells and new beginnings, that the tears we shed can transform into strength for the future.
Its moving message—about overcoming the conflicts and worries of youth to discover hope—resonates deeply.
The structure, shifting from a pure melody to an emotionally charged key change at the climax, further enriches the lyrical world.
Released in January 2008 as a double A-side single with “BE FREE,” this track was later included on the acclaimed album “Ah, Hello There, Long Time No See.” It just might gently warm the hearts of those who feel anxious about taking a new step forward.
