The first half of the 20th century

In 1943, as Japan was embroiled in WWII, the stock exchange in Tokyo was combined with ten other stock exchanges in major Japanese cities to form a single Japanese Stock Exchange, the Nippon Shōken Torihikisho (日本証券取引所). Shortly after the nuclear bombing of Nagasaki, this exchange was shut down and reorganized.

A few years after the end of the war, the Tokyo Stock Exchange reopened under its current name Tōkyō Shōken Torihikijo (東京証券取引所) on May 16, 1949. Japan now had a new Securities Exchange Act.

The second half of the 20th century

The 1980s was a period of extreme growth and capitalization for major Japanese companies. The TSE runup from 1983 to 1990 was astonishing, and by 1990 the TSE accounted for more than 60% of the world’s total stock market capitalization.

On April 30, 1999, the TSE trading floor was closed down to switch the exchange from manual to electronic trading for all transactions.
