Solution:

Try a ground-up approach. In a city of 1 million (Kyoto), how many people are of marriageable age? Let’s say 750,000. How many get married in a given year? Maybe 2 percent? That’s 15,000. Now, the population of Japan is about 150 million, so multiply 15,000 by 150 – and you get 2.25 million weddings every year. Divide that by 365 and you get 6,164 weddings per day (on the average, though clearly some days are more popular than others).

To summarize:

There are 1 million people in Kyoto.

750,000 are of marriageable age.

2 percent get married in the average year.

750,000 x 0.02 = 15,000 marriages every year in Kyoto.

There are 150 million people in Japan.

150 x 15,000 = 2.25 million weddings per year. 2,250,000/365 = 6,164 weddings per day.
