The two-building property at 9740 Irvine Blvd. employs about 800. The main Irvine office had housed some employees of Toshiba Corp.'s medical systems operating unit, which makes diagnostic imaging systems and was recently sold to Canon Inc. in a $5.9 billion deal. Toshiba executives said they're looking for a new location for existing operations, preferably close to the current campus. The campus is projected to fetch a sales price of $80 million to $100 million, according to real estate sources familiar with the property. Longtime company veteran Satoshi Tsunakawa this month was nominated for the top post at Toshiba Corp. following an accounting scandal that prompted the resignation of the former chief executive, chairman and eight board members, leaving the conglomerate financially battered, facing record losses, deep job cuts and other potential divestitures.
