Jobs in Japan?

Trak asks: "I've always been fascinated by Japanese culture and would love to spend a few years living there. Making a long story, short: my wife just left and I've got some savings, so I'm considering the move. I have a some jobs here in The States that I could rely on for telecommuting work, but I'd rather find a job there in The Land of the Rising Sun. Any advice on where to look and what to pursue? Any horror stories? I've done it all from System Admin to Programming to CTO, so I'm open to just about anything that's available, I just don't know where to begin looking. Thanks."
