If Tokyo were a country…Comparing the GDP of Japan’s 47 Prefectures to International GDPs

If the city of Tokyo were a country, its gross domestic product (GDP) of about $976 billion would place it between Spain’s ($1,042 billion) and the Netherlands ($914 billion).

In this article, we breakdown the prefectural and regional GDPs of the 47 prefectures and seven regional blocks of Japan (as defined by Japan’s Cabinet Office) to give our readers an idea of the relative size and contribution of the various regions of Japan to the overall economy and how they compare to various countries in the world.


Here are a few key points to know about the economy of Japan and the country’s key cities and regions:

  • Japan has the third largest economy in the world, with a 2018 GDP of $4,791 billion, ranking behind the United States and China.
  • Tokyo’s GDP of $976 billion (in 2016) comprises about 19% of Japan’s GDP.
  • The combined GDP of the Kanto region (which consists of the prefectures of Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Yamanashi, and Nagano) is about $2,097 billion, compared to Italy’s GDP of about $2,084 billion (2018).
  • The second biggest prefectural economy in Japan is Aichi ($368 billion), a major international automotive manufacturing hub and headquarters to Toyota.
  • Osaka ranks third in Japan, with a GDP of $364 billion.
  • There are major disparities between the urban centers and rural prefectures of Japan. In 2016, 35 prefectures in Japan had GDPs that were 10% or less of Tokyo’s.
  • Tottori has the smallest of Japan’s GDPs, at about $17.4 billion.
