As a Canadian, I noticed that we were relatively overrepresented her in Japan compared to our American neighbours. While the US’s population is about nine times of ours, their population in Japan was only five times ours. This got me curious, and so I did some number crunching, dividing the number of foreign residents in Japan by country by the population of their country of origin, and then multiplying the result by one million to get something easily comparable.

Not surprisingly, Korea was the most represented in relative terms, in large part owing to Japan’s wartime legacy. Other asian countries ranked high, as did South American countries such as Peru and Brazil, which boast large ethnic Japanese populations.

The surprising outlier was New Zealand. With 3,672 residents of Japan but a relatively small population of 5 million, it boasts the proportionally highest number of residents among English speaking countries.
