Former IWGP Heavyweight champ Okada appeared inside of the the Lucha Underground Temple Saturday ... but not to wrestle, he was only there to watch.

The Rainmaker posed for a pic with Rey Mysterio and the show's EP Eric Van Wagenen posted it on Twitter with the caption, "Look who stopped by the tapings today..."

No word on whether Kazuchika was there to talk business or not, but our Lucha sources tell us the wrestler caught up with friends in the locker room after the show.

Now excuse us while we sit and dream of a potential match between Okada and Pentagon Jr.

Wrestling Gods, please make it happen one day.
