Fanuc Corp. and Yamanashi Prefecture

Yamanashi Prefecture: Outsiders are rarely allowed at its complex in Yamanashi Prefecture on the slopes of Mount Fuji, where an army of yellow robots work 24/7 making more robots in windowless yellow factories, according to The Japan Times. Email is mostly banned and Fanuc Corp., one of Japan s most reclusive companies, has spent decades building a wall of secrecy around its ultra-profitable industrial-robotics business. Business is often done by fax to keep computer viruses out and technology in. (news.financializer.com). As reported in the news.
