Which Countries are Most Similar to Japan? 2.0

Have you ever wondered how similar or different two countries are? The Country Similarity Index attempts to quantify how similar countries are to each other relative to other countries. The index is a statistically-based way to measure this. It weighs equally five major aspects of countries: their demographics, culture, politics, infrastructure, and geography. The methodology is exactly the same for each country. The research combines 1,000 different data points to arrive at the conclusions.

Similar to South Korea and Taiwan

Very few countries are similar to Japan. The closest two would be their neighbors, South Korea and Taiwan. They are well developed, democratic East Asian countries that border the North Pacific Ocean. Outside of the countries in Asia, Western European countries are the most similar, since they have a similar climate and infrastructure. Still, they have huge cultural differences with Japan, except that they are not particularly religious.

The least similar countries are all located in Africa, most specifically in the Sahel region. These countries are all quite poor and do not have well developed infrastructure. Furthermore, they are sparsely populated deserts with some of the highest temperatures in the world.

Top 10 Places Most Similar to Japan

  1. South Korea was annexed by Japan in 1910 and was part of Japan until the end of World War II. The demographics and geography of these countries are significantly similar.

  2. Taiwan was another protectorate of Japan until the end of World War II. Both countries are mountainous islands in the Pacific, with well developed shipping infrastructure. One difference is that Taiwan’s climate is more tropical. While Taiwan doesn’t drive on the left, it does use 3′-6″ railroad tracks and Type A B electrical outlets with 110 voltage, like Japan. Both countries also use Traditional Chinese characters in their writing. Like South Korea, it is another Asian country that is interested in baseball, although it is not as prolific in the Olympics.

Furthermore, China’s geography has much more variety. It has a large percentage of both subtropical and desert areas.

In addition, some aspects of their demographics are similar. The average age of their people is among the oldest in the world and their average income is similar as well. However, the personality of their people are opposites, as the Japanese tend to be more reserved than the outgoing Italians.
