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.
If this article sparks your interest in modulation, please explore further by searching online.
Understanding how songs are put together will surely open up a whole new way to enjoy music!

Songs with satisfying key changes. Classic J-POP and Japanese tracks where the mood and impression shift naturally (61–70)
Things that have formShibasaki Kou
In addition to her work as an actress, Ko Shibasaki began her career as a recording artist after playing a singer in the film “Yomigaeri.” You could say she’s one of the leading examples of an artist who found great success after starting out as an actress.
From her catalog, the song I recommend for its satisfying key change is “Katachi Aru Mono.” It modulates right before the chorus; because the key change happens just before the transition from the B-melody to the chorus, the flow is extremely smooth.

ClassicJUDY AND MARY
Released in October 1996 as JUDY AND MARY’s 10th single.
The song was originally written by guitarist TAKUYA for a solo project, but there’s an anecdote that it ended up being released by JUDY AND MARY because YUKI was determined to sing it.
It was used as the opening theme for TBS’s “Pop-file” and in a TV commercial for Nissin Foods’ “Vegetable Soup Noodles.” As for the modulation, the key change happens in the chorus after the interlude, where the key goes up.
As a setup for the modulation, the phrase right before the chorus is sung once in the original key and then a second time in the higher key, which clearly signals a scene change and allows the key to shift smoothly without feeling out of place.
There are also phrases and chord progressions—such as in the third measure of the A section—that make it feel as though the key changes, but it’s tricky to decide whether to treat these as actual key changes or simply as accidentals.
Since the track features only piano and vocals, listen closely to the piano and enjoy the richness of the chord progressions.
rainbowAqua Timez
Aqua Timez is a rock band that gained popularity with its straightforward lyrics and melodies.
Although the band disbanded in 2018, they reunited for one year starting in 2024, which created a lot of buzz.
Among Aqua Timez’s songs, one piece particularly notable for its key change is Niji (“Rainbow”).
It was a nationwide hit, so many of you have probably heard it.
In this track, the final chorus features a classic modulation that raises the key by a whole step.
Combined with the lyrics and overall tone, the key change creates a distinctly hopeful atmosphere.
Naughty SunORANGE RANGE
When the signs of summer start to show, this is the quintessential ORANGE RANGE killer tune you just can’t help but crave! The lyrics, which capture a scorching, smoldering love and an impulse that breaks past reason, deliver a rush that makes your body temperature rise just by listening.
Released in July 2007 as their 17th single, the track was also used as the opening theme for the hugely popular drama “Hanazakari no Kimitachi e ~ Ikemen Paradise ~.” The flow from the sultry mood of the first verse into the explosive sense of release in the chorus shifts the song’s feel so dramatically that it gives you a thrilling lift akin to a key change.
It’s no wonder it hit No.
3 on the Oricon weekly chart—an indispensable song for summer drives and karaoke.
SUNHoshino Gen
This is an exhilarating track that modernizes ’70s dance classics, the kind that makes your body start moving just by listening.
Its lyrics feel like rays of hope breaking through the darkness, paired with an open, life-affirming sound that’s truly captivating.
Released as a single by singer-songwriter Gen Hoshino in May 2015, it was used as the theme song for the drama “Kokoro ga Pokitto ne” (Crazy For Me).
Also included on the acclaimed album “YELLOW DANCER,” the song features meticulous arranging—from the analog synth in the intro to the soaring chorus—that naturally guides listeners toward a brighter state of mind.
It’s a perfect pick when you want to feel joyful for no particular reason or shake off everyday melancholy and dance your heart out.
Finishing Blow feat. Cory WongVaundy
Singer-songwriter Vaundy commands overwhelming support, especially among younger generations, with his originality-rich musicality.
While his early work was rooted in rock, the influence of Black music has become more pronounced as his career has progressed.
“Todome no Ichigeki feat.
Cory Wong” falls into the latter category, characterized by elements of neo-soul, disco, and funk.
Notably, the song features a major key change in the pre-chorus, yet despite the shift in mood, the transition feels seamless and natural.
Ponytail and ScrunchieAKB48
This is the 16th major single by the Japanese female idol group AKB48, released in May 2010.
Lyrics by Yasushi Akimoto, music by Shinya Oda.
Idol songs may have a reputation for being “simple and straightforward,” but the modulation techniques used in this track are quite intricate and very skillful.
It might be out of place to go into overly technical details here, so I’ll refrain, but within this song, rather than abrupt, scene-changing shifts, it achieves very smooth, natural-sounding modulations through the use of carefully crafted chord progressions.
