Continuing Wandering Palaceside around Palaceside Building — back to Eiichi Shibusawa, who founded many Meiji-era firms.
Alongside Dai-Ichi National Bank, a major Shibusawa project was the stock exchange — predecessor of today's Tokyo Stock Exchange in Kabutocho, three stops on the Tokyo Metro Tozai Line from Takebashi at Kayabacho.
The Meiji government issued bonds for nation-building; group trading began near Ningyocho. As joint-stock companies spread, stock trading grew and an exchange was needed. In May 1878 the Stock Exchange Act passed; Shibusawa, Mitsui & Co. head Takatoshi Mitsui, and others applied; Finance Minister Shigenobu Okuma licensed them. Tokyo Stock Exchange opened June 1. Shibusawa's residence faced the exchange.
Wartime merger into Japan Securities Exchange, trading halt, GHQ dissolution, then revival as Tokyo Stock Exchange in 1949.
Kabutocho became Japan's capitalist hub — brokers, Mitsui, and major firms clustered around the exchange.
Today's TSE main building (photo) completed 1988; the market hall opened late 1984. After Black Monday (October 1987) stocks surged into the bubble — the building looked very bubble-era indeed.
