              Sony Corporation Announces New Management Structure

TOKYO, Japan, Mar. 7, 2005- Sony Corporation's current management team today
proposed the creation of a new management structure designed to expand upon its
core strengths as a global electronics, entertainment and technology company.
The proposal was approved at the Board of Directors' Meeting held today.
Effective June 22, subject to approval at Sony Corporation's Ordinary General
Shareholder's Meeting that day, the following new management team will lead the

1)  Sir Howard Stringer (currently Chairman & CEO Sony Corporation of
    America, Corporate Executive Officer, Vice Chairman and COO Sony 
    Entertainment Business Group) will assume the position of Chairman, Group 
    CEO and Representative Corporate Executive Officer, Sony Corporation.  Sir 
    Howard will run Sony's overall group business operations on a global basis 
    from headquarters in both New York and Tokyo.  In this new position, he will
    also continue in his role as the head of the Entertainment Business Group 
    and head of Sony Corporation of America.
2)  Dr. Ryoji Chubachi (currently Corporate Executive Officer, Executive
    Deputy President and COO of MSNC and EMCS) will assume the position of
    Representative Corporate Executive Officer, President of Sony Corporation 
    and CEO of the Electronics Business Group of the company.  In this new 
    position, Dr. Chubachi will have overall responsibility for Sony's 
    electronics businesses worldwide.
3)  Mr. Katsumi Ihara (currently Corporate Executive Officer, Executive
    Deputy President and Group CFO) will assume the role of Representative 
    Corporate Executive Officer, Executive Deputy President and Group CFO, Sony 
    Corporation.  Mr. Ihara will oversee financial matters and support Sir 
    Howard and Dr. Chubachi with respect to overall corporate strategy and 
    resource allocation.

The current management team led by Mr. Nobuyuki Idei, Representative Corporate
Executive Officer, Chairman and Group CEO has implemented an effective
reallocation of group-wide resources and promotion of cross-border alliances
within the Sony Group. This has resulted in the significant strengthening of the
entertainment content businesses, the solidifying of the mobile phone business,
the development of the next generation semiconductor chip, and the integration
and expansion of the financial services business.  As a result, Sony is now
poised to move forward with its global entertainment, electronics and technology

This is a pivotal year for Sony Corporation, and this new structure will enable
the company to streamline its operation, and provide a more cohesive focus for
operating its businesses around the world in a proactive and strategic manner.

In addition the Nominating Committee agreed to submit the nomination of the
following officers as Board member candidates to be formally appointed at the
meeting of Sony Corporation's Ordinary General Shareholders' Meeting on June 22,
2005 in Tokyo.

While formal appointments will be made on June 22, this management transition
will begin effective immediately.

Nobuyuki Idei, who has served as Director, Representative Corporate Executive
Officer, Chairman and Group CEO and Kunitake Ando, currently Director,
Representative Corporate Executive Officer and President will become Chief
Corporate Advisor and Advisor of Sony Corporation, respectively, as of June 22
and will continue to support the new management team from an overall Sony Group
management standpoint.

(Comments from Nobuyuki Idei) From June, the Sony Group will have a new
management team centering on Sir Howard Stringer and Dr. Ryoji Chubachi. Both
men have a deep understanding of Sony's great tradition and through their open
management style they will focus intensely on energizing the entire Sony Group.
Sir Howard is an executive admired both within the Sony Group and in the wider
business community. His global perspective allows him to bring Sony's
electronics and entertainment groups together and to integrate their resources
effectively. Naturally, Sir Howard fully understands Sony's longstanding spirit
of freedom and open-mindedness. Dr. Chubachi's deep experience with the
electronics business and profound understanding of technology issues have won
the respect of Sony's engineering community. The new management team of Sir
Howard and Dr. Chubachi joined by Mr. Ihara will work together to successfully
integrate Sony's abundant resources in electronics, entertainment and
technology. I have great confidence in their ability to lead Sony boldly and
flexibly into the future. It has been the greatest honor for me to lead Sony for
10 years as this global company has transitioned from analog to digital,
integrated its electronics and entertainment cultures and moved into the
broadband age. I have the highest expectations for Sony as it begins a new phase
under a new management team.

(Comments from Kunitake Ando)
Since I became President in 2000, there have been radical changes in the global
business environment. However, I firmly believe that the current management team
has laid the foundations for future growth. Our mobile phone business has been
revitalized through the establishment of Sony Ericsson Mobile Communications
(SEMC) and we have created a stronger and more efficient production, sales and
distribution platform. With this base secured, Mr. Idei and I concur that now is
the best time to make the transition to a new management team. Our designated
President Mr. Chubachi has a deep knowledge of the key devices that are
essential to success in the technology and electronics business. He also fully
understands the production processes that are at the heart of any manufacturing
company and I believe he is the right person to lead Sony's electronics business
into its next phase of development. I urge all Sony employees to give their full
support to the new management team as we move forward to a new era for Sony.

(Comments from Sir Howard Stringer)  I am delighted to be joining Dr. Chubachi,
Mr. Ihara and the extremely talented global management team to lead Sony
Corporation.  Sony has an unparalleled legacy of boldness, innovation and
leadership around the world.  Together we look forward to joining our twin
pillars of engineering and technology with our commanding presence in
entertainment and content creation to deliver the most advanced devices and
forms of entertainment to the consumer.  I am grateful to Mr. Idei and to Mr.
Ando for the confidence they have shown in me, and the Sony Board of Directors
for their support, and to the many talented executives throughout this
organization who have shown their desire to lead and to innovate.  We have
clearly demonstrated in our US operations that we can achieve significant
cross-company efficiencies, and at the same time deliver both extraordinary
quality and record returns.  I believe the entire global organization is hungry
to make this same transition, and all of us in senior management are committed
to achieving that goal.

(Comments from Ryoji Chubachi)  This is a pivotal time for Sony Corporation, and
I keenly feel my responsibilities.  My first priority is to revitalize our
electronics business in close coordination and cooperation with Sir Howard and
Ihara-san.  Building on Sony's legendary corporate culture of creativity and
speedy implementation, we will work to deepen communication and enhance our
entire group performance. I will give Sir Howard full support to achieve the
paramount goal of transforming Sony.

(Comments from Katsumi Ihara)  The next chapter in Sony's history will be its
most exciting.  We have already made tremendous strides to expand cross-company
initiatives and address business efficiencies. The solid growth of our US
operations and the continued brand strength there will help inspire many of our
future activities.   Since I joined Sony, I have experienced almost all areas of
the company's consumer electronics business. I also have had opportunities to
manage Sony's overseas affiliates. Together with Sir Howard and Chubachi-san I
look forward to the many opportunities before us.
