so I know there are a couple japanese (NTSC J) Xbox 360 games, like Mushihimesama Futari and Max Anarchy, that play on US systems..

being as thats still just DVD format, I was wondering if anyone knew of any NTSC J playstation 2 games that are also region free?

I'd mod my ps2, but she's my 2002 fat and I don't want to risk it lol

I had my slim PS2 modded, it broke down a few years later, it still runs but the screen on the TV is black, wether that's because of the mod chip or not idk, luckily I still have my fat PS2, luckily PS2s are pretty cheap so if you don't mind getting a second hand one its not that big a deal to mod it and it breaks.

Use Swap Magic

you dont even need swap magic, as long as you have 007 Agent under Fire and can take apart your fat ps2. heres part one to a video that shows you how to do it:

You can get 007 for about 4-5$ on amazon: http://www.amazon.com/gp/offer-listing/B00005NUIZ/ref=dp_olp_used?ie=UTF8&condition=used&qid=1372661297&sr=8-1

If you have a ps3 theres a way to run ps2 isos: http://www.youtube.com/watch?v=W_Uco2Gxxwk

Why do you need to take PS2 apart? I did not. Swap Magic (or any exploit, 007 or whatever else) + Open PS2 Loader > profit. Not sure how that'd work on fat though and current status of compatibility. Anyway if TS is planning to import games and don't want bother with modding (soft or hard) -- Swap Magic is a solution.
