The Jade Passage - this site is in beta right now, but has some info. on it that not even I could dig up(that's not saying a lot...) seriously, check this guy's site out
Final Fantasy 2j Page - an old, incomplete website on FF2j. It was last updated in 1999, so I guess this was the only victim of Y2K. I dunno.
***If you find a FF2j site, or have one, then e-mail me the link.
