To help keep up with puroresu, here are a number of sites that can give more extensive information of the great sport in Japan:

Puro Love - Your one stop for all puroresu results
Strong Style Spirit - For more New Japan Information
Splash Mountain -
For Mike Campbell's Puroresu Reviews
Inside Pulse -
Weekly Puroresu Column by David Ditch
Death Valley Driver Message Board - The best message board for Puroresu, which I can say since it is moderated by Ditch and myself :)
The Great Hisa's Puroresu Dojo - Not updated frequently but good for older puroresu information
