How to say "metropolis" in Japanese

Choosing the right word
  • 首都しゅとJLPT N3approx.Common
    nounFor 'metropolis' meaning a country's capital city. It denotes the chief city where a nation's government sits, so it suits talk of national capitals rather than big cities in general.
    東京とうきょうは日本にっぽんの首都しゅとです。↗
    Tokyo is the capital of Japan.
  • 大都市だいとしCommon
    nounFor 'metropolis' meaning simply a very large city. Use it for any big, major city, whether or not it is the capital; this is the word when size, not political status, is the point.
    このバスは2つの大都市だいとしをつないでいる。↗
    This bus connects the two large cities.

Use 首都 when 'metropolis' means a country's capital city, and 大都市 when it means simply a very large city, whether or not that city is the capital.
