My database contains sixteen shrines located in Ginza in Chuo-ku in the heart of Tokyo. Of these sixteen, eleven are Inari Jinja meaning that there is one Inari Jinja for every 270 of Ginza’s resident population. I suspect that this  is the lowest such number in Japan, and by extension in the world. Of course the number for daytime population—people working in shops and offices, sightseers, shoppers etc—is much higher. I haven’t been able to find a figure for Ginza’s daytime population but for Chuo-ku as a whole the daytime/resident population ratio is 3.84: applying this to Ginza the number of Inari Jinja per head of daytime population rises from 270 to 1,038, still a very low number. 

​

These shrines are all very small and often quite difficult to find. Some are down alleyways and most of them are seemingly pressed into the side  of buildings. "Easy to photograph" is not a phrase which readily springs to mind when describing them.

The ones described on this site so far are: Asahi Inari Jinja, Azuma Inari Jinja, Enbujo Inari Daimyojin, Toyoiwa Inari inja, Saiwai Inari Jina.
