Japan

Japan is made up of over 3000 islands, a total landmass almost as large as the state of California. The four main islands are Honshu , the largest, followed by Hokkaido, the most northern and also the least populated, then Kyushu, the southernmost, and Shikoku. Stretching 3000km from north to south, the northernmost regions of Japan are subarctic, while the extreme south is subtropical.

Four-fifths of the land surface is mountainous and rural; most of the 127 million people who live on the four main islands are packed into the coastal plains. This has led to the development of so-called ‘urban corridors’, the longest of which, and perhaps the most densely inhabited in the world, is the Tokaido belt between Tokyo and Osaka.

Apart from Hokkaido all the main islands in Japan are divided into prefectures 県 (ken); there are 47 in all. However, Tokyo is known as Tokyo-to (metropolitan prefecture), and both Osaka and Kyoto as -fu (urban prefectures).

  • the kanji for the prefecture
  • the abbreviation used in Japan by Rail for the general area: CH (Central Honshu), Kan (Kansai), WH (Western Honshu), Toh (Tohoku), Hok (Hokkaido), Kyu (Kyushu), Shi (Shikoku)
  • the region the prefecture is part of
  • where relevant the prefecture’s capital city (‘Pref cap’).
