                      Tokyo Stock Exchange or TSE, located in Tokyo, 
                      Japan, is the second largest stock exchange 
                      market in the world by market value, second only to the 
                      New York Stock Exchange.
  It 
                      currently lists 2,271 domestic companies and 31 foreign 
                      companies, with a total market capitalization of over 5 
                      trillion USD. [1] The 
                      Tokyo Stock Exchange was established on May 15, 1878, as 
                      the Tokyo Kabushiki Torihikijo under the direction 
                      of then-Finance Minister Okuma Shigenobu and capitalist 
                      advocate Shibusawa Eiichi. Trading began on June 1, 1878. |  |  |

                incorporated as a kabushiki kaisha with nine directors, four auditors 
                and eight executive officers. Its headquarters are located at 
                2-1 Nihombashi Kabutocho, Tokyo, Japan. Its operating hours are 
                from 9:00 to 11:00 am, and from 12:30 to 3:00 pm. From April 24, 
                2006, the afternoon trading session started at its usual time 
                of 12:30 p.m. Stocks listed 
                on the TSE are separated into the First Section (for large companies), 
                the Second Section (for mid-sized companies), and the "Mothers" 
                section (for high-growth startup companies). As of March 2006, 
                there are 1,721 First Section companies, 489 Second Section companies 
                and 156 Mothers companies. The main indices 
                tracking the TSE are the Nikkei 225 index of companies selected 
                by the Nihon Keizai Shimbun (Japan's largest business newspaper), 
                the TOPIX index based on the share prices of First Section companies, 
                and the J30 index of large industrial companies maintained by 
                Japan's major broadsheet newspapers. 89 domestic 
                and 19 foreign securities companies participate in TSE trading.

                The exchange's 
                  press club, called the Kabuto Club, which meets on the third 
                  floor of the TSE building. Most Kabuto Club members are affiliated 
                  with the Nihon Keizai Shimbun, Kyodo News, Jiji Press, or business 
                  television broadcasters such as Bloomberg LP and CNBC. The Kabuto 
                  Club is generally busiest during April and May, when public 
                  companies release their annual accounts.  On 15th June 
                2007, the TSE paid $303 million to acquire a 4.99% stake in Singapore 
                Exchange Ltd. [2] History  
                 
                   
                    
                    The Stock 
                    Exchange occupies a narrow site in Tokyo's securities district  Prewar 
                history The Tokyo 
                Stock Exchange was established on May 15, 1878, as the Tokyo 
                Kabushiki Torihikijo under the direction of then-Finance Minister 
                Okuma Shigenobu and capitalist advocate Shibusawa Eiichi. Trading 
                began on June 1, 1878. In 1943, the 
                exchange was combined with ten other stock exchanges in major 
                Japanese cities to form a single Japanese Stock Exchange. The 
                combined exchange was shut down and reorganized shortly after 
                the bombing of Nagasaki. Postwar 
                history The Tokyo 
                Stock Exchange reopened under its current Japanese name on May 
                16, 1949, pursuant to the new Securities Exchange Act. The TSE runup 
                from 1983 to 1990 was unprecedented, in 1990 it accounted for 
                over 60% of the world's stock market capitalization (by far the 
                world's largest) before falling precipitously in value and rankings 
                today, but still remains one of the 3 largest exchanges in the 
                world by market capitalization of listed shares. The trading 
                floor of the TSE was closed on April 30, 1999, and the exchange 
                switched to electronic trading for all transactions. A new facility, 
                called TSE Arrows opened on May 9, 2000. In 2001, the 
                TSE restructured itself as a stock company: before this time, 
                it was structured as an incorporated association with its members 
                as shareholders. The exchange 
                was only able to operate for 90 minutes on November 1, 2005, due 
                to bugs with a newly installed transactions system, developed 
                by Fujitsu, which was supposed to help cope with higher trading 
                volumes. The interruption in trading was the worst in the history 
                of the exchange. [3] Trading was suspended for four-and-a-half hours. During the 
                initial public offering of J-Com on December 8, 2005, an employee 
                at Mizuho Securities Co., Ltd. mistakenly typed an order to sell 
                610,000 shares at 1 yen, instead of an order to sell 1 share at 
                610,000 yen. Mizuho failed to catch the error; the Tokyo Stock 
                Exchange initially blocked attempts to cancel the order, resulting 
                in a net loss of 347 million US dollars to be shared between the 
                exchange and Mizuho. Both companies are now trying to deal with 
                their troubles: lack of error checking, lack of safeguards, lack 
                of reliability, lack of transparency, lack of testing, loss of 
                confidence, and loss of profits. On 11 December, the TSE acknowledged 
                that its system was at fault in the Mizuho trade. On 21 December, 
                Takuo Tsurushima, chief executive of the TSE, and two other senior 
                executives resigned over the Mizuho affair. [4] [5] [6] [7] [8] [9] [10] [11] On January 
                17, 2006, the Nikkei 225 fell 2.8%, its fastest drop in nine months, 
                as investors sold stocks across the board in the wake of a raid 
                by prosecutors on internet company livedoor. The Tokyo Stock Exchange 
                closed early on January 18 due to the trade volume threatening 
                to exceed the exchange's computer system's capacity of 4.5 million 
                trades per day. This was called the "livedoor shock." The exchange 
                quickly increased its order capacity to five million trades a 
                day. [12]  Alliances London Stock Exchange and Tokyo Stock Exchange 
                are developing jointly traded products and share technology, marking 
                the latest cross-border deal among bourses as international competition 
                heats up. Tokyo Stock exchange is also looking for some partners 
                in Asia, and more specifically with Singapore Exchange, which 
                is considered as becoming a leading financial hub in Asia-Pacific. 
                Recently, some rumors close to the deal are telling that Tokyo 
                Stock Exchange is preparing for the first semester of 2008 a takeover 
                the Singapore Exchange, or at least take a major stake. In June 
                2007, Tokyo Stock Exchange already purchased a 5% of SGX, and 
                it is only the beginning of a bigger participation. References |
