ATTN: Japanese PSN Users (Yakuza demos)

[HellHammer]

I have recently become a huge Yakuza fan. And after tracking down the ones available in the US, I wanted more. I read about the release of Yakuza 4 and Ryū ga Gotoku Kenzan! both having demos on the Japanese PSN and quickly made a Japanese account.

HOWEVER! Sony apparently takes down some game demos after the game is released, and both the demos for 4 and Kenzan! are no longer available. (though strangely 3's demo is still active...?) I am sad.

HOWEVER AGAIN! I was told that if an account had already downloaded the demos, even if they've been deleted since, it could re-download them.

So I'm wondering, on the off chance that someone really likes me, if anyone who's downloaded either Yakuza 4 or Kenzan! would be willing to loan me their account info to download the demos myself? I promise I'm a cool dude and I'm not looking to swindle anyones account or anything.
I know it's a long shot, but I'm feeling lucky today.
