It is least likely that Japan will be experiencing population growth.
Explanation:
Japan is a country that has a very large population for a country of its size, over 120 million people. Japan though, faces huge demographic problems, which will be more and more serious as the years pass by. The problems now are not that the population is very large, but that the population is aging and will start to experience sharp decrease in the coming decades.
The total fertility rate (TFR) of the country is only 1.27, which is far from enough for simple replacement of the population, as for that a TFR of 2 is needed. Less and less children are born, which in turn provides smaller and smaller population for reproduction with each generation. On the other hand, Japan is a country that has one of the highest life expectancy in the world, and the old population is constantly on the rise.
Such situation brings in lot of economic problems, as very soon the number of old people will equal the number of people of working age, and that is almost impossible to be managed. The Japanese governments have been trying to persuade the young people to form a family and have more children, but the reality is the opposite, as more and more young people decide to be solitary, not form a family, and if they do, they tend to have one child, or maybe two.

The correct answer is - kilometers.
Very often, the map scale is showing distances in both miles and kilometers. The reason for this that the majority of the countries in the world use the metric system, thus the kilometers are a must, but also there countries that do not use this system, thus they include the miles. In this way, the map scale can be used by people that both use and not use the metric system in their daily lives.
The map scale is a very important element on the maps. Its purpose is to enable the reader of the map to be able to measure the distance from one place to another, thus to be aware of the real distance in the real space.
