Look at the following lists...

Metros by GDP 2008

Metros by GDP 2020
http://www.citymayors.com/statistics/richest-cities-2020.html

And theres many more... don't you think it's weird Nagoya is not on any of them but Fukuoka is? Nagoya is the third largest metro in Japan and has one of the highest GDP per capita.. according to this
http://www.i-bac.jp/economy/index.html

Nagoya's metro GDP isn't that far behind Osaka's...

So my question is why is Nagoya missing in all the international data/rankings of cities?? It should be in the top 20 to 30 at least.

Interesting, and good question. Of course, you can always email the website and provide the data and sources, as well as contribute to the wikipedia entry.

According to the city of Nagoya, its GDP accounts for 1% of the global economy, and another website claims the GDP of the Nagoya Metro area is greater than the nation of Switzerland.

Thanks for the replies! Unfortunately the data in your links is from 2004...I wish I could find some data for 2008/2009. I would like to update many statistics..

According to your link Nagoya was 10.7% of Japan's GDP in 2004 and it's GDP was 459 billion. In 2010 Japans GDP is $5.273 trillion, assuming Nagoya is still 10.7% of Japan's GDP Nagoya's 2010 GDP is 564 billion. Assuming it dropped to 10% then Nagoya's GDP is 527.3 billion.

That would put Nagoya as the 8th or 9th largest metro GDP in the world and a GDP per capita of (assuming the GDP is 564 billion) at $62,667. If the GDP in 2010 is 527.3 instead of 564 the GDP per capita is $58,556 which is the highest per capita GDP of all (large) metros in Japan.

Brisavoine in the international section calculated GDP of cities in 2009 and it seems accurate to me (he didn't include Mie prefecture in the Nagoya metro).

GDP in 2009 at market exchange rates:
1. Tokyo metro area: 1,605 billion US dollars
2. New York metro area: 1,427
3. Los Angeles metro area: 853
4. Paris metro area: 779
5. London metro area: 712
6. Osaka-Kobe-Kyoto metro area: 671
7. Washington-Baltimore metro area: 533
8. Chicago metro area: 521
9. San Francisco Bay Area: 489
10. Rhine-Ruhr metro area: 487
11. Nagoya metro area: 430
12. Houston metro area: 408
13. Randstad metro area: 394
14. Dallas-Fort Worth metro area: 388
15. Seoul-Incheon metro area: 367
16. Moscow metro area: 349

Nagoya is #11 so I really can't understand why all the rankings don't even have Nagoya in them.
