Tokyo, Japan — It is with great sadness that Sony Corporation today announced the loss of Norio Ohga, Senior Advisor and former President and Chairman, Sony Corporation. Mr. Ohga passed away at 9:14 AM on April 23, 2011 in Tokyo. The cause of death was multiple organ failure. He was 81 years old. A private wake will be held among family and close relatives, and a company service will take place at a later date.
When I worked at Sony Ohga was the man running the company and Morita was the visionary. Years before I joined, Ohga was the person who came up with the “Walkman” product that was the start of the personal music player which was a massive success for Sony.
