The 57 year-old from Kinokawa in southern Japan, is reckoned to have been viewing 10,000 pages a day, or 20 every minute when his frensied wibbling was at its most vigorous.
Kinokawa official Tomiko Waki told journalists the porn king's surfing habits had gone unnoticed since the he was seated away from other staff who could not see what was on his screen.
They put his strange noises down to personal peccadillos, it seems.
The lightning surfer was found out after he picked up a computer virus and technical support examined his browser's history. He was subsequently demoted and suffered a pay cut.
It is not clear whether the man will now have his desk anywhere near less distracted workers. ยต
