HEROMr.Children
This song, released in December 2002 by Mr.Children—the indispensable four-piece rock band in Japanese music history—is a moving work created right after Kazutoshi Sakurai’s return from a cerebellar infarction.
The lyrics, infused with the desire to be someone’s hero, are full of gentle resolve: not to be a dazzling presence, but to stand by someone important in everyday life.
Chosen as the theme song for the NTT DoCoMo Group’s 10th-anniversary commercial, it became a long-running hit, ranking 9th on the 2003 annual singles chart.
It’s a number to play when you want to reaffirm your feelings for someone important or when you need a nudge forward.
MelissaPorunogurafiti
Released in September 2003 as their 12th single, this is one of the signature songs by Porno Graffitti, the rock duo from Hiroshima Prefecture.
It was used as the opening theme for the TV anime Fullmetal Alchemist and is also known for winning Song of the Year at the 18th Japan Gold Disc Awards.
The lyrics, imbued with the will to reclaim what’s been lost and the resolve to move forward while healing a wounded heart, resonate deeply with listeners.
Beginning with a striking bass riff, the song’s high-velocity sound and powerful vocals fuse into an arrangement that’s guaranteed to fire up any karaoke session—a rock number you’ll want to belt out with friends.
sympathetic tearsHitoto Yo
The debut single by singer-songwriter Yo Hitoto, who has a Taiwanese father and a Japanese mother and continued making music in an a cappella club while attending Keio University.
Released in October 2002, the song reached No.
4 on the Oricon charts without a major tie-in and became a long-running hit, staying on the chart for 70 weeks.
The lyrics, which depict how a friend’s tears set off a chain reaction of emotions, are said to have been inspired by a heartbreak she experienced during her university years.
The striking chorus was crafted so that it can be sung universally using only vowels, creating a unique world where an Oriental, R&B-tinged arrangement and her resilient, powerful vocals blend exquisitely.
In 2003, the song earned her the Japan Record Award for Best New Artist and her first appearance on the NHK Kohaku Uta Gassen, making it the track that defined her career as an artist.
Greatful daysHamasaki Ayumi
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.
Two Red Starskinmokusei
Kinnmokusei’s biggest hit ran a razor-thin line with an exquisite mix-and-balance of Black soul and Japanese kayō pop.
It’s no exaggeration to say the song is structured with a perfectly crafted kishōtenketsu worthy of going down in history.
If it had tied up with Sapporo Lager Beer, it might have become an even bigger hit.
