If i were a wantrapeeneur id be seeing what app services tokyo specifically from and economic and cultural perspective as if you can monitize just fraction of tokyo businesses......
Tokyo is not a city. It's a metropolitan area and one of the 47 prefectures in Japan. It contains a bunch of special wards, towns and cities inside it with their local governments.
The special wards of Tokyo are even called cities in English by the wards themselves. One example is Shibuya City: http://www.city.shibuya.tokyo.jp
I don't think the point your parent is making hinges on the definition of city. The Tokyo metropolitan area is smaller and more populous than than all of California. One can refer to LA or New York as cities and mean to include their metropolitan areas. Washington, DC is a separate political jurisdiction which is usefully and colloquially referred to as a city as well.
So basically that one city has the population of caifornia.
