* ColbertBump: Even though ''VideoGame/SuperSmashBros'' does this for a lot of obscure Nintendo series, a surprising amount of players got into the series because of a ''very'' well-received remix-medley for ''Trendsetters'' in ''[[VideoGame/SuperSmashBrosForNintendo3DSAndWiiU for Wii U]]''. ''VideoGame/SuperSmashBrosUltimate'' adding the song "Ring a Ding" from ''Styling Star'' also led to a boost in the series' exposure.
* CreatorCameo: The choreographer for ''Styling Star'', Mikiko of Elevenplay, appears near the end of the game as one of the player's clients.
* NoExportForYou:
** The boyfriend DLC in ''Trendsetters'' and many, many DLC featuring clothes inspired in RealLife Japanese brands didn't leave the West. There's exclusive DLC in Europe depending on the country, but it's much more lackluster.
** Games after ''Trendsetters'' have not been released in South Korea.
** Subverted in the case of ''Styling Star's'' release. It was only given a digital release on the Nintendo eShop in North America compared to the Japanese and European physical releases. This also means that ''Styling Star'' is [[KeepCirculatingTheTapes legally unavailable in North America]] as of August 2022, since the 3DS eShop disabled adding new funds.
** There are several manga and novel adaptations that have never left Japan.
* UrbanLegendOfZelda: There are a few persistent rumors that you can date and even get married if you perform certain "secret" actions in-game. While an update to ''Trendsetters'' did feature the ability to get a "Dream Boyfriend" among other things, this update [[NoExportForYou has yet to extend outside of Japan]].
