So many cool looking apps, will it run on my PalmOS?

I'm always excited when I find new sites full of PalmOS software. And tonight I found one while blindly clicking links. This site shows so many screenshots of the software looking all colorful and cool.

Will this software run on my PDA if it is not a japanese model or do I need the japanese PALMOS installed, for some items you wouldnt need to know what it says for those who can not read japanese because well games are games and they are easy enough to figure out ;)
