The climate of Japan is predominantly temperate, but varies greatly from north to south. Japan's geographical features divide it into six principal climatic zones: Hokkaido, Sea of Japan, Central Highland, Seto Inland Sea, Pacific Ocean, and Ryukyu Islands. The northernmost zone, Hokkaido, has a temperate climate with long, cold winters and cool summers.

More than 99 percent of the population speaks Japanese as their first language.[2] It is an agglutinative language distinguished by a system of honorifics reflecting the hierarchical nature of Japanese society, with verb forms and particular vocabulary indicating the relative status of speaker and listener.

The yen is the official national currency of Japan, and is denoted by JPY. The Meiji government introduced the yen to replace the previous complex system of the Edo Period, where there was no fixed exchange rate between the various coins used.
