Language entries introduce the main language; they do not describe every language spoken in the country. ## Put the country on your mental map. Find Japan off the eastern coast of Asia. Its four main islands are Hokkaido, Honshu, Shikoku and Kyushu. Reading the islands from north to south is a useful first step toward understanding the country’s regions. Tokyo sits in the Kanto region on Honshu. A capital-city study can start there, then branch into another region to see how much variety exists within one country. Japan’s national tourism organization provides a useful [Tokyo and region guide](https://www.japan.travel/en/destinations/kanto/tokyo/). Look beyond the label ### Islands and regions How does an island setting help me understand Japan’s regions? ## A flag you can describe from memory. ![Flag of Japan](https://www.smartworldmap.com/assets/flags/countries/jp.svg) Flag of Japan Japan’s flag has a red disc on a white field.

A shared shape can lead you to three different countries.

Kyoto is another well-known city with a different historical and cultural story. Keeping their names distinct helps you place both in your mental map. When you study a country, separate the city’s role from its familiarity. Make a pair on your notes: the country name on one side, its capital on the other. Test it before opening the answer in [the capital practice guide](https://www.smartworldmap.com/learn/countries-and-capitals/). ## Make this country part of your next five minutes. Locate Tokyo, find Honshu, and then look for the other three main islands. Write the capital and currency from memory before checking the essentials again.
