   Sony Communication Network Corporation (hereinafter, the "SCN Group"), a
subsidiary the performance of which is linked to a tracking stock issued by
Sony Corporation, announced today its consolidated results for the second
quarter ended September 30, 2004 (the period from July 1, 2004 to September 30,
2004) and the six-month period ended September 30, 2004 (the period from April
1, 2004 to September 30, 2004). 
   These results are based on the generally accepted accounting standards of 
   Japan.

-    For the three months ended September 30, 2004, increased revenue and a 
     large increase in income compared to the year earlier period.
     During the quarter under review, sales increased 3.3%, compared with the 
     year earlier period, to 10,010 million yen.  This was a result of increases
     in the revenue of Internet-related services.  Furthermore, as a result of
     cost reduction in the area of Internet provider services and improvements 
     in profitability at subsidiaries, operating income of 780 million yen was 
     recorded, compared with an operating loss of 187 million yen in the year 
     earlier period.  Ordinary income of 720 million yen, compared with an 
     ordinary loss of 110 million yen, was recorded.  Net income increased 
     greatly to 2,367 million yen, compared with a net loss of 155 million yen 
     in the year earlier period.  Net income for the quarter under review 
     included extraordinary gain from an initial public stock offering by a 
     subsidiary and sale of subsidiary stock

-    So-net subscribers remain flat
     At the end of the quarter under review, the number of So-net subscribers 
     was about flat at 2.29 million.  The number of broadband subscribers 
     reached 580,000, an increase of 90,000 over the end of the year earlier 
     period.

-    Fiscal Year 2004 Forecast (revised)
     Regarding the Forecast of Consolidated Results for the year ending March 
     31, 2005, the forecast announced on September 8, 2004 has been revised.  
     Currently, the SCN Group expects sales of 40,000 million yen, operating 
     income of 2,500 million yen, ordinary income of 2,500 million yen, and net
     income of 3,300 million yen.

Summary of Consolidated Operations (July 1, 2004 to September 30, 2004)
----------------------------------
Regarding sales, during the quarter under review, sales increased 3.3% to 10,010
million yen, compared with 9,691 million yen in the year earlier period.
In the area of Internet provider services the market as a whole increased in
size, with the number of broadband users (including ADSL, FTTH(Optical Fiber),
and CATV) in Japan at the end of September having passed 17 million. (Data
according to the Ministry of Public Management, Home Affairs, Posts and
Telecommunications.)
For the SCN Group, in the area of Internet provider services, sales decreased.
Although the number of SCN Group broadband subscribers was 90,000 larger than
the year earlier period, totaling 580,000, the number of narrowband subscribers
decreased.
In the area of Internet-related services, sales increased. This was mainly a
result of an increase in viewer fees for CS broadcasting and an increase in
sales at subsidiaries. Also, there was an increase in the area of merchandise
sales.
Furthermore, the total number of So-net subscribers at the end of the period
under review was 2.29 million, roughly flat with the year earlier period.

Regarding operating income, there was an improvement. During the quarter under
review, an operating profit of 780 million yen was recorded, compared with an
operating loss of 187 million yen in the year earlier period.
The main factor in the improvement was a series of cost reductions. For example,
for the item cost of sales, there were cost reductions related to integration of
access points, including outsourcing work charge in network operation, for
network lines costs, and for leases charge of servers and such. Furthermore, for
the item selling, general and administrative expenses, there were reductions in
costs for outsourcing work stemming from more efficient use of call centers, and
improvements in advertising and marketing expenses as well as other fixed costs.
In addition, there were improvements in the profitability of subsidiaries.

Regarding ordinary income, during the quarter under review, ordinary income of
720 million yen was recorded, compared with an ordinary loss of 110 million yen
in the year earlier period.
Under the item of non-operating income, equity income of 4 million yen was
recorded. Under the item of non-operating expenses, there were one-time expenses
connected with a public stock offering of a subsidiary, and disposition of fixed
assets.

Regarding net income, during the quarter under review, net income of 2,367
million yen was recorded, a significant improvement over a net loss of 155
million yen recorded during the year earlier period.
This was largely the result of the public offering of shares in an SCN Group
subsidiary, So-net M3. Inc. Due to this offering, extraordinary gain was
recorded, including gains from issuance of subsidiary stock of 1,821 million yen
and gains from sale of subsidiary stock of 2,344 million yen. On the other hand,
concerning unlisted equity investment, loss on investments in other securities
of 878 million yen was recorded as a result of a decline in the fair value of
such stock resulting from a worsening of financial conditions of investee
companies. Also, an extraordinary loss of 295 million yen was recorded as a
result of impairment losses in subsidiaries' fixed assets. As a result of the
above, net income before income taxes was 3,604 million yen and taxes including
corporate tax totaled 1,226 million yen during the quarter under review.

Operating revenue
ISP services
In this category, the SCN Group has worked to expand its service area for ADSL
and FTTH by cooperating with telecom carriers and has worked to enrich its FTTH
offerings. The SCN Group has also worked to carry out promotional campaigns to
acquire new subscribers, and for narrowband subscribers, the SCN Group has
worked to solicit subscriber transitions to broadband services.
As a result, the number of broadband subscribers increased, but the number of
narrowband subscribers decreased. Overall, sales of ISP services for the quarter
under review were 7,290 million yen, a decrease of 6.7% compared with the year
earlier period. Such sales accounted for 72.8% of total sales.

Internet-related services
In this category, the SCN Group increased sales of services, such as systems for
online games and viewer fees for CS broadcasting "So-net Channel 749," which is
programming focused on popular Korean dramas such as "Truth" and "Shoes of
Glass." Also, at group subsidiary Skygate, Co., Ltd., there were increases in
commission revenue related to increased air ticket transactions, and at So-net
M3 Inc., which carried out a public stock offering in September, there were
revenue increases stemming from expansion of "MR-kun." As a result, sales in
this category during the quarter under review increased 47.5% to 2,463 million
yen. Sales in this category accounted for 24.6% total sales.

Merchandise sales
In this category, sales steadily increased at e-commerce sites, including the
theater-related site "e-oshibai.com", the animation site "Animax Online Shop",
and online fashion shopping mall "Select Square", which brings together a
variety of famous shops. As a result, sales in this category during the quarter
under review increased 24.2% to 258 million yen. Sales in this category
accounted for 2.6% of total sales.

Results of Consolidated Subsidiaries and of Affiliated Companies Accounted for
by the Equity Method

The SCN Group includes the following four consolidated subsidiaries: So-net
Sports.com Corp., So-net M3 Inc., So-net M3 U.S.A. Corp., and Skygate, Co., Ltd.
Affiliated companies accounted for by the equity method include Label Gate Co.,
Ltd. and DeNA Co., Ltd.
During the quarter under review, So-net M3 Inc. listed its shares on the Tokyo
Stock Exchange "Mothers" board on September 16, 2004. At this time, both new
stock was issued and existing stock was sold, so the shareholding ratio of
So-net M3 Inc. and its subsidiary So-net M3 U.S.A. Corp. held by the SCN Group
declined to 74.8%.
During the quarter under review, equity income of 4 million yen was recorded,
compared with 2 million yen during the year earlier period, due to the continued
strength at DeNA Co., Ltd.'s auctions site and other e-commerce sites.



Cash Flow (April 1, 2004 to September 30, 2004)

Cash and cash equivalents were 8,434 million yen at the end of the six-month
period ended September 30, 2004, an increase of 6,253 million yen from the end
of the prior fiscal year, and an increase of 6,880 million yen from the end of
the year earlier period. During the six-month period under review, the SCN Group
generated 1,812 million yen of cash in operating activities, generated 2,240
million yen of cash in investing activities, and generated 2,201 million yen of
cash in financing activities.

Cash flows from operating activities

During the six-month period ended September 30, 2004, regarding cash flows from
operating activities, the SCN Group generated 1,812 million yen, compared with
the six-month period ended September 30, 2003 when the SCN Group used 350
million yen. This was mainly due to net income before income taxes in the period
under review of 4,374 million yen, compared with a net loss before income taxes
of 441 million yen in the year earlier period. Also, included in the net income
before income taxes during the period under review was such non-cash expense as

million yen, and amortization of goodwill of 142 million yen, and such non-cash
income as gain on sales of subsidiary stock of 2,344 million yen and gain on

investing activities, the SCN Group generated 2,240 million yen, compared with
the six-month period ended September 30, 2003 when the SCN Group used 879
million yen. The main factor in the period under review was proceeds of 2,577
million yen from the sale of subsidiary stock, which was a result of the sale of
stock by the SCN Group when the Group's consolidated subsidiary So-net M3 Inc.
listed on the Tokyo Stock Exchange Mothers board. Also, outlays for acquisition
of intangible assets such as connection services, e-commerce related systems,
and homepage development were 338 million yen, compared with outlays of 366
million yen in the year earlier period.

Cash flows from financing activities

During the six-month period ended September 30, 2004, regarding cash flows from
financing activities, the SCN Group generated 2,201 million yen, while during
the six-month period ended September 30, 2003, the SCN Group used 600 million
yen. During the period under review, this reflected the issuance of subsidiary
stock at the time of the listing of the Group's consolidated subsidiary So-net
M3 Inc. on the Tokyo Stock Exchange Mothers board.

Consolidated Results Forecast (revised)

Regarding the forecast of the consolidated results for the fiscal year ending
March 31, 2005, the SCN Group has revised towards improved profitability the
forecast previously announced on September 8, 2004.
The reasons for the revisions are as follows:
     
1.   Regarding operating income, the main factor is a reduction in fixed costs 
     stemming from both cost reductions, in areas such as network usage related
     to the integration of access points, outsourcing, and leases, and 
     structural improvements.
2.   Regarding ordinary income, the main factor is the above expected 
     improvement in operating income.
3.   Regarding net income, in the quarter under review, a loss on revaluation
     of investments in other securities of 878 million yen and a loss on 
     impairment of long-lived assets, including lease assets at subsidiary, of 
     295 million yen were recorded. Furthermore, in the third quarter ending 
     December 31, 2004, it is expected that a gain of 533 million yen from the 
     sale of 740 shares in an over-allotment relating to the public offering of
     So-net M3 Inc. will be recorded. These factors, together with an increase 
     in the tax expenses related to the revision in ordinary income, and the 
     revision in ordinary income itself, are the main reasons for the revision 
     in forecast net income.

The SCN Group announces the following forecast for consolidated results as of
October 28, 2004:




                                                               (millions of yen)
