Is there a Japanese website that hosts guides for old/non-localized games?

I'm playing a game atm called Shadow Tower Abyss for the PS2. And I have came across a couple of guides in English, but I've heard people reference a Japanese website (either dead links or no links) that lists the drops of every enemy in the game, and item layouts + maps for every area, and in NG+ (items change in NG+).
