- The lyrics for Owari-Hajimari, and Lullaby for You were changed from Japanese to English.
- Slash and Slash was renamed Slam Brothers in international versions. The song is titled Slash Brothers in the Japanese version of the game though, the soundtrack is the only one that titles it Slash and Slash.
- Rush Hour is an "unused" song that is not used in both versions of the game. The song is still purchasable from AMX or Towa Records in-game, but does not appear in any other game context.
- Both soundtracks would be eventually combined for the international version of The World Ends with You -Solo Remix- for mobile devices, and subsequently Final Remix on the Switch.
- Brainy Cat pin have changed slightly to remove religious symbolism.
- Japanese version had four pins (Polytan, Gemaga, Nindori-kun, and Famitsu) which were references to Japanese gaming magazines (Dengeki, Gemaga, Nintendo Dream, and Famitsu respectively). Their icons and descriptions were changed to Fuji Yama, Daruma, Sushi, Shinobi in the NA/EU version. The stats of the pins did not change.
- (Confirmed) Character or Noise attack/defense have changed slightly. Some enemies, mostly Boss Noise and Taboo Noise, do more damage in the Japanese version. Enemies such as Grizzlies also do more damage in the Japanese version.
- Mingle PP rewards have increased in the US/EU version.
- Espers from 20 to 50 MPP each
- Ordinary People (AKA Civvies) from 3 to 20 MPP each
- Aliens from 20 to 100 MPP each
- Many items' stats improved; below is just one example.
- Angel Feather: from ATK -24, HP +600 in the Japanese version to ATK +30, DEF +30, HP +2000 in the US/EU version
- Eden's Door evolved into 1 Yen in the Japanese version - a devastating punishment for evolving the Holy Field pins incorrectly. In the US/EU version it evolves back into One Jump from Eden.
- There's one more ESP'er Rank after "Demon," the "God" rank. In JP it was earned at exactly 65,535 ESP'er Points. This was reduced in NA/EU to 10,000, but was erroneously left as exactly 10,000 points instead of being changed to at least 10,000; the rank reverts to "Demon" at 10,001 and beyond.
