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.

Understanding how songs are put together will surely open up a whole new way to enjoy music!

Songs with key changes that feel great: classic J‑POP and Japanese hits where the mood and impression shift naturally (71–80)
NEXT LEVELYU-KI
This is the second solo single by TRF’s lead vocalist YU-KI, released in March 2006.
It served as the opening theme for the TV Asahi tokusatsu drama Kamen Rider Kabuto.
The key change in this song modulates in the chorus from F minor to D minor, adding three flats (theoretically a modulation up a major sixth).
It clearly signals the modulation to listeners while causing little sense of incongruity, and it’s also a relatively straightforward modulation in terms of chord arrangement.
Silent majorityKeyakizaka46
It’s the debut single of Keyakizaka46, released in April 2016.
In the chorus, the song modulates from the key of G# minor to F minor, a “+#3 modulation.” While the key change itself feels natural, the B-melody phrase right before the chorus is deliberately crafted not to connect smoothly to the chorus.
This heightens the impact of the chorus and gives listeners the illusion that the song briefly moved to a different key just before it.
The use of such sophisticated arranging techniques may well be a hallmark of modern idol songs.
I think it’s a track with a very intriguing chord arrangement.
Just the two of usRADWIMPS
Released in May 2006, this is RADWIMPS’ third major-label single and sixth single overall.
In this song, the key changes starting from the first chorus (around 1:34), then returns to the original key from the second chorus—a modulation used to make the chorus stand out more.
While many hit songs up through the ’90s only modulated for the final chorus, since the 2000s there’s been a rise in songs that use these slightly more technical modulations, which really feels like an evolution in J-pop.
The arrangement that highlights the chorus without feeling unnatural is superb.
Tomorrow as wellSHISHAMO
With a cute singing voice that expresses down-to-earth worries and makes listeners feel, “I’ll do my best again tomorrow,” SHISHAMO’s girls’ band anthem “Ashita mo” does just that.
It’s a very simple, catchy, and easy-to-listen-to song, but if you look at it from the perspective of key changes, it’s actually doing something quite complex.
The chorus modulates, and in a way that’s rare in J‑POP: it goes up by six semitones.
Typically, to modulate you use chords common to both the original and new keys, but when you jump up six semitones, there are almost none.
So they deliberately switch up the vibe dramatically, giving listeners a strong impact!
DepartureGReeeeN
Released in 2008 as GReeeeN’s sixth single, this song reached No.
10 on the Oricon Weekly Singles Chart.
It vividly portrays his feelings as she sets off to pursue her dreams.
Though he feels lonely, he sends her off with a smile and cheers her on—making it a moving, tear-jerking track.
CAN YOU CELEBRATE?Amuro Namie
It was released in 1997 as Namie Amuro’s ninth single.
Chosen as the theme song for Fuji TV’s Monday 9 p.m.
drama “Virgin Road,” it topped the Oricon charts for two consecutive weeks and achieved double million-seller status.
With this song, she won the Grand Prize at the 39th Japan Record Awards, marking her second consecutive win.
cherry blossomKobukuro
It was released in 2005 as Kobukuro’s 12th single.
It was selected as the theme song for the Fuji TV drama “Ns’ Aoi” and became a long-running hit.
At the 47th Japan Record Awards, it won the Gold Award and became Kobukuro’s second best-selling single.
It’s a highly popular “sakura song.” The key change when it goes into the chorus feels so natural and satisfying, doesn’t it?
