Japan is an insular country covered by forest or mountains on 73% of its surface. As a result, the mainly habitable regions have a high density of population.
The country is divided into 8 regions: Hokkaido, Tohoku, Kanto, Chubu, Kansai, Chugoku, Shikoku, Kyushu (incl. Okinawa).
LANGUAGE: The official language is Japanese. In the biggest cities (Tokyo, Osaka, Kyoto…) some persons speak English, but out of these regions is very difficult to communicate in English.
But don’t worry the Japanese will always find a way to communicate.
ELECTRICITY: Electricity in Japan is 100V (50Hz in Tokyo, Tohoku y Hokkaido) and (60Hz in Kyoto, Osaka,…). The plug is type A/B.
If you use 110 V in your country you will be able to use your electric appliances. If your country uses 220V-240V (Spain, France, Germany, UK, Australia…) you will need a converter.
