Japan- all cities

Japan Info Guide

Japan covers a total area of approx. 378.000 sqkm with an approximate of 130 million citizens.
The biggest city is the capital of Tokyo, with approx. 9 million citizens (if you would count all suburbs, this number rockets up to almost 35 million).
Japan is a parliamentary monarchy with Shintoism and Buddhism being the dominant religious believes.

Japans international country code is +81.
Japan consists of approx. 6000 islands, with the 4 main- and biggest islands being the northern island of Hokkaido, the central island of Honshu and the southern islands of Shikoku and Kyushu in the south.
Almost 73% of the terrain is mountainous, with Mt. Fuji (3.800) as the highest hammock. Due to this fact, agriculture almost entirely is done in the form of terraces.

Japan Weather Guide

The climate in Japan is very diverse.
You will find a rather climate, with long snowy winters in Hokkaido and sub-tropical climate in Okinawa.
A “rule of thumb” would read like this:

  • Hokkaido: only a few breaks of heavy rain, winters long and cold.
  • Japanese Sea: partly heavy snowfall during the winter. In the summer, cooler than the Pacific regions with dry winds from time to time.
  • Central Plateau: mostly dry with stark contrast between summer- and winter temperatures. Also between day and night.
  • Seto Lake: the surrounding mountains block the wind and create a mild climate throughout the year.
  • Pacific Region: cold winters with little snow, hot and dry summers.
  • Ryukyu Islands: sub- tropical climate with mild to warm winters and hot summers. You will see a lot of high winds up to typhoon- force during the rainy season.

Japan's meteorologists clearly divide the year into 4 seasons:
Spring (March to Mai) with mild climate. This is the time of the cherry- and peach- blossoming, starting at the end of March in the south and ending at the end of April in the north.
Summer (June to August/ September) is equal to the rainy season. It is warm but also very humid, with some typhoons forming. August and September usually sees the highest typhoon- activity with lots of (sometimes heavy) rainfall.
Autumn (September to November) sees mostly mild temperatures.
Winter (December to February) shows a division between the cold and rather snowy west and cool but a lot dryer east of the country.
