Similar to Love the World, the Perfume song 575 was featured in a cell phone commercial, this time for the iida Lightpool in 2010. The version of the song used in the CM sounds the same, only shorter to fit the runtime.
This collaboration seemed uneventful until 2021 when a vinyl appeared on Yahoo japan auctions (page no longer exists) that contained the "575 light pool mix". Many fans suspected this could be an alternate version of 575.
The vinyl was bought and has not since surfaced on the internet, meaning it is unlikely that we will find out whether this was a new remix or just a short edit of the song.
