That's the same uploader for 2kki, .flow and Nisshi.
The japanese RTP has been posted at least twice in the 2kki thread, and there's a 2kki download in /media/ that has both english and japanese RTP. Also you have no idea of how many different english RTPs are around >_>
Finally, no, it won't mess up anything. Applocale changes the locale of only the programs you choose, and YN is originally japanese too. I have the habit of opening RPGMaker in japanese locale so I can load the fangames' projects, and it's never messed up YN for me; it was actually nice, because the names of the maps in the RPGMaker project were readable and not a bunch of messed up characters. xD
Oh, also, if ANYTHING is zipped or rar'd, from the RTP to the game, open your WinRAR with applocale, as it will impede stuff from being extracted with the wrong name (or not extracted at all, like it does sometimes). Install the RTP with applocale too, because it normally stops at 44% if it's not run with japanese locale.
