The sixth single released in February 2015 by chay, who is active as both a model and a singer-songwriter, became popular as the theme song for the Monday 9 p.m.
drama “Date—What Is Love Like?” starring Anne.
The song is packed with the pure feelings of a protagonist who’s clumsy in love.
Its retro, pop sound reminiscent of the ’60s, complemented by lush strings, perfectly captures the giddy excitement of the moment a romance begins.
The lyrics portray that magical, empowering feeling that makes you think you can do anything just because there’s someone you like—something many listeners can relate to.
It’s a bright, pop number you’ll want to play to lift your spirits, like right before meeting someone special.
Because it’s so warm♪kumamushi

A song by the comedy duo Kumamushi, born from the unique premise of “being reborn as a girl and making an idol debut.” It originally started as part of a manzai routine, but its catchy melody and phrases quickly became a hot topic.
Like serving a special dish to someone dear, this work delivers straightforward kindness and affection, touching many hearts.
Shunsuke Hasegawa’s sweet, translucent vocals further enhance the song’s warm atmosphere.
Released as a single in February 2015, it was also featured in commercials and drew major attention, including becoming the first entry by a comedian in about three years to reach the Oricon Weekly Top 10.
It’s a track brimming with charm—one that gently spreads warmth when you listen to it on a slightly chilly day.
It’s not me unless it’s meGesu no Kiwami Otome.

This is a celebrated song whose philosophical lyrics, affirming one’s unique self, resonated with many.
Released in April 2015 as Gesu no Kiwami Otome’s second single, it became widely known through a Coca-Cola commercial.

Performed at the 66th NHK Kohaku Uta Gassen, this track is one that gently gives you a push when you’ve lost confidence or feel down from comparing yourself to others.
New Treasure IslandSakanakushon

From the very first bars, it’s a retro-yet-fresh dance number that sets your heart racing! Released in September 2015 as Sakanaction’s 11th single, this track—by a band that masterfully fuses rock and dance music—was chosen as the theme song for the film “Bakuman.” The nostalgic synth tones and irresistibly buoyant beat are simply addictive.
The piece reflects the figure of a creator who, like a manga artist racing their pen across the page, persistently sketches out the future.
Even while carrying anxiety and inner conflict, the careful pursuit of ideals feels like an anthem cheering on everyone striving to create something.
It’s the perfect song for lifting your spirits and stepping forward with a positive mindset.
User ManualNishino Kana

Kana Nishino’s 27th single, written as the theme song for the film “No Longer Heroine.” The lyrics, which depict the delicate feelings of women—perhaps a bit hard for men to fully grasp—through the unique lens of an “instruction manual,” resonated widely.
Opening with words of gratitude, the song rides a bright country-pop melody to express a wish to be accepted fully, moodiness and all.
Released in September 2015, it was also included on the acclaimed album “Just LOVE,” and went on to win both the Excellence Award and the Grand Prize at the 57th Japan Record Awards the same year.
Beloved as a wedding staple, it’s a perfect number to help convey your feelings to someone special.
