Songs with satisfying key changes: classic J-POP and Japanese tracks where the mood and impression shift naturally
There’s a technique called “modulation” that’s used when you want to dramatically change a song’s scene or mood partway through.
If we were to explain modulation in depth, it would be enough to fill an entire music theory book, so I’ll skip the details here.
The most common pattern is raising the key for the final chorus to heighten the excitement.
There are also songs that, for example, modulate only in the pre-chorus to catch the listener off guard, as well as songs that skillfully modulate repeatedly while still sounding natural, using subtle modulation techniques.
This time, I’ve picked out a few songs where the modulations feel particularly pleasing or are especially well crafted.

Songs with satisfying key changes: Iconic J-pop and Japanese tracks where the mood and impression shift naturally (31–40)
YesterdayOfisharu Higedan Dism
Released in September 2019, this Official HIGE DANDism track was also chosen as the theme song for the film HELLO WORLD.
Official HIGE DANDism often creates songs with very stylish arrangements, and in this piece, they achieve a refined sense of “sophistication” by modulating in the B section from F-sharp major to F minor—a parallel-key modulation.
The shift is so smooth that some listeners might not even notice it.
While this might deviate slightly from the main focus of this article, I chose this song to illustrate that modulation isn’t only about sudden, striking changes.
This kind of modulation is fascinating, too.
Brilliant RainKing Gnu
King Gnu’s “Ame Sansan” makes effective use of modulation to the parallel key.
The song starts in G minor and, in a simple structure, modulates to the parallel key of B-flat major for the chorus, giving you that exhilarating feeling as the scenery shifts from a mysterious intro to a suddenly clear, refreshing sky.
The melody is also cleverly crafted, featuring quite large intervallic leaps.
If you plan to sing it at karaoke, it might be best to practice by hitting each note accurately one by one before the actual performance.
Romantic Flightkome kome CLUB
It was released in 1990 as Kome Kome Club’s 10th single.
The song was used as the commercial image song for JAL’s Okinawa travel “JAL STORY Summer Rikyu Campaign,” reached No.
1 on the Oricon Weekly Singles Chart, and became a million seller.
It is one of Kome Kome Club’s signature songs.
I want to hug you.Mr.Children
This is the second single by Mr.Children, a monster band known for their overwhelming scale, and a quintessential love song that represents the 1990s.
Although sales were modest at the time of its release, it gained popularity after the band’s breakthrough and became widely recognized—even being featured in the Reiwa era.
Its simple, highly relatable lyrics resonate straight to the heart.
The structure moves from the intro into a key change for the vocals, uses B-flat in the chorus, and modulates to C in the final chorus, delivering that uniquely reassuring, soaring Mr.Children melody.
The climactic lift in the last chorus—almost a textbook move—is excellent, and the natural modulations that enhance the song’s appeal are truly captivating.
My RevolutionWatanabe Misato
A signature song by Misato Watanabe, released in 1986.
That sparkling intro grabs you right away.
The lyrics sing of living strongly and true to yourself.
With a key change that actually drops from the high pre-chorus into the chorus to make it easier to sing, and an uncommon structure for the time that weaves in three downward key changes in the chorus, it left listeners with a fresh impact.
Some say the birth of this song sparked the rise of frequent key changes in J-pop.
Beyond the charm of those modulations, Omura’s superb arrangement is another highlight.
With its beautiful tones and Misato’s soaring vocals, it’s a classic that leaves a bittersweet yet radiant impression.

me me sheRADWIMPS
A heartbreaking ballad where emotions and “dear” memories intertwine.
Included on RADWIMPS’s album RADWIMPS 4: Okazu no Gohan, it was released in December 2006.
The first half moves quietly with a steady 8-beat, but towards the latter half the arrangement swells like surging emotion, as if a cry from the heart is spilling out.
The lyrics have resonated strongly—garnering over two million views on lyric sites—and the band’s expressive power is astonishing: even without flashy key changes, they radically transform the song’s impression using dynamics alone.
If you just can’t sever your lingering feelings for a former lover, it might be good to immerse yourself in this song and have a good cry.
maybeYOASOBI
This is the fourth digital single by YOASOBI, a duo that turns novels into music.
Released in July 2020, it was also included on their first EP, THE BOOK.
The song was selected as the theme for a film based on the original novel.
Its comfortable mid-tempo feel and chord progressions that change character from scene to scene draw listeners in.
The quiet of a morning after a breakup and ikura’s transparent vocals merge to express a tender, wavering emotion.
The arrangement, which incorporates everyday sounds, and the lyrics—blending resignation with lingering attachment—wrap the entire track in a pleasing atmosphere.
The delicate shifts in sound serve as elements that change the impression as if the key had modulated.
With each listen, you can sink deeper into the protagonist’s feelings—please savor that lingering afterglow.
It also makes a great soundtrack for time spent alone.
