Chinese nationals (137). Economy Tokyo has the largest metropolitan economy in the world. According to a study conducted by PricewaterhouseCoopers, the Greater Tokyo Area (Tokyo–Yokohama, TYO) of 38 million people had a total GDP of $2 trillion in 2012 (at purchasing power parity), which topped that list. Tokyo is a major international finance center; it houses the headquarters of several of the world's largest investment banks and insurance companies, and serves as a hub for Japan's transportation, publishing, electronics and broadcasting industries. During the centralized growth of Japan's economy following World War II, many large firms moved their headquarters from cities such as Osaka (the historical commercial capital) to Tokyo, in an attempt to take advantage of better access to the government. This trend has begun to slow due to ongoing population growth in Tokyo and the high cost of living there. Tokyo was rated by the Economist Intelligence Unit as the most expensive (highest cost-of-living) city in the world for 14 years in a row ending in 2006, when it was replaced by Oslo, and later Paris. Tokyo emerged as a leading international financial center (IFC) in the 1960s and has been described as one of the three "command centers" for the world economy, along with New York City and London. In the 2020 Global Financial Centers Index, Tokyo was ranked as having the fourth most competitive financial center in the world (alongside cities such as New York City, London, Shanghai, Hong Kong, Singapore, Beijing, San Francisco, Shenzhen and Zurich in the top 10), and second most competitive in Asia (after Shanghai). The Japanese financial market opened up slowly in 1984 and accelerated its internationalization with the "Japanese Big Bang" in 1998. Despite the emergence of Singapore and Hong Kong as competing financial centers, the Tokyo IFC manages to keep a prominent position in Asia. The Tokyo Stock Exchange is Japan's largest stock exchange, and third largest in the world by market capitalization and fourth largest by share turnover. In 1990 at the end of the Japanese asset price bubble, it accounted for more than 60% of the world stock market value. Tokyo had 8,460 ha (20,900 acres) of agricultural land as of 2003, according to the Ministry of Agriculture, Forestry and Fisheries, placing it last among the nation's prefectures. The farmland is concentrated in Western Tokyo. Perishables such as vegetables, fruits, and flowers can be conveniently shipped to
