- Allows Foreign Investors to Directly Assess TSE Systems via Ultra-low
Latency Global Connectivity -

TOKYO, April 11, 2013 /PRNewswire/ -- Tokyo Stock Exchange (TSE) partners with
NTT Communications Corporation to launch its arrownet-Global network service
in Hong Kong. Leveraging NTT Communications' Ethernet Leased Line service and
ultra-low latency cable systems, including the Asia Submarine Cable Express
(ASE), the new connectivity offering will enable global financial service
institutions in Hong Kong to directly access JPX Co-location (all), the new
co-location service of Japan Exchange (JPX), and TSE's systems for the first

arrownet is a highly reliable low latency network service offered by TSE since
2009 for financial service institutions to connect with its trading and
information systems and also co-location racks in Tokyo. With the availability
of arrownet-Global, overseas financial institutions can now directly connect
to JPX Co-location (all) and TSE's system, thereby strengthening the
exchange's value proposition while broadening its investor pool.

NTT Communications' long-term relationship with TSE, wide network
infrastructure and established track record are key reasons for its selection
by TSE as the exchange's first partner in launching arrownet-Global. In
addition, the availability of this service over the ultra-low latency ASE that
bypasses major seismic locations offers additional assurance in meeting the
demand for reliable services.

Mr Yoshinori Suzuki, Senior Managing Director of Tokyo Stock Exchange
commented, "arrownet-Global enables the global investors in Asia and across
the world to access the JPX market from outside of Japan more easily and
effectively by realizing a seamless connection with arrownet via NTT
Communications' wide global coverage. I hope that straightforward access to
the JPX market will strengthen the value of TSE's IT infrastructure and boost
the liquidity of the JPX market, so that JPX can achieve its corporate aim to
become 'the Most Preferred Exchange in the Asian Region'."

NTT Communications provides end-to-end network solution with its Ethernet
Leased Line service, which connects the clients' systems in Hong Kong all the
way through to JPX Co-location and TSE's system in Tokyo. Clients will be able
to enjoy one-stop services from ordering to network infrastructure design and
maintenance with NTT Communications as the single contact point.

The service will also ride on NTT Communications' new ASE cable system that
connects key financial hubs in Asia through the shortest possible route. This
ASE cable system boasts industry leading network latency of less than 43
milliseconds from Hong Kong to Tokyo and less than 65 milliseconds from
Singapore to Tokyo. Latency can be further optimized by co-locating the
clients' systems at NTT Communications' new Financial Data Centre (FDC(TM)) in
Hong Kong, where the ASE cable landing station and NTT Communications' global
network node are located.

"Our experience, solid track record and ability to exceed the stringent
expectations of our financial services industry clients are instrumental in
this partnership. Currently, we provide network connectivity to a wide range
of financial clients, and we pride ourselves in our ability to understand
their demands on latency and reliability. Our partnership with TSE and the
launch of arrownet-Global in Hong Kong cements our strong industry leadership
in networking and one-stop solution approach on global connectivity," said
Patrick Ng, Executive Vice President, Global Network Business Division, NTT
Com Asia.
