Pre-release interest in Nickelodeon All-Star Brawl managed to stretch out into the Japanese Super Smash Bros. fandom, despite Nickelodeon series not being particularly popular in Japan and the channel being taken off the air in 2009. The initial popularity of the game would lead to an official Japanese release (with only in-game text being translated to Japanese) after work on the DLC was finished in 2022, something that no other Nickelodeon game by GameMill Entertainment has had, including the game's sequel. While the game's popularity would die down like it did elsewhere, steep sales and cheap discount prices would result in a regional competitive scene for the game reappearing and frequent appearances on the Nintendo Switch's sales charts. This would lead to it peaking at number #6 on Japan's Switch download charts for the entire year of 2024, beating out all of Nintendo's first-party titles on the hardware, including Super Smash Bros. Ultimate.
