Shikoku (四国), Japan

Ritsurin Garden in Takamatsu, Kagawa Prefecture


Shikoku is one of the four main islands of Japan. It covers 18,000 sq km (7,260 sq mi). In terms of size, Shikoku is the smallest of the four main islands. It has a population of 4.1 million people, making it the least populous main island, even less than that of Singapore (which is only 712 sq km/274.2 sq mi). Shikoku measures about 225 km (139.8 mi) from end to end. Its width is between 50 km to 150 km.

The island is subdivided into four prefectures namely Ehime, Kagawa, Kochi and Tokushima. These were created out of the former provinces of Awa, Iyo, Sanuki and Tosa during the Meiji Restoration of the 19th century.

Shikoku is separated from Honshu by the Inland Sea. Across the Inland Sea are the prefectures of Wakayama, Osaka, Hyogo, Okayama, Hiroshima and Yamaguchi. To the west of Shikoku is the island of Kyushu.

Shikoku is quite mountainous. As a result, most of the population of the island is concentrated along the coast facing the Inland Sea, and in selected areas facing the Pacific Ocean. The tallest peak in Shikoku is Mount Ishizuchi (), which is 1,982 m (6,503 ft) tall. The longest river is Yoshino River (吉野川), which is 196 km (121.8 mi) long. The river ranks as the top whitewater ranking destination in Japan.

Planning your trip to Shikoku

Getting to Shikoku is now most convenient by road, as the island is connected to mainland Honshu by a number of expressways linked by massive bridges. The Kobe-Awaji-Naruto Expressway connects eastern Shikoku to Honshu, the Seto-Chuo Expressway connects Central Shikoku to Honshu, while the Nishiseto Expressway connects Western Shikoku to Honshu.

The Kobe-Awaji-Naruto Expressway crosses the Akashi Strait from Hyogo Prefecture in Honshu to Tokushima Prefecture in Shikoku, connected by the Akashi-Kaikyo Bridge and Onaruto Bridge. The Great Seto Bridge, which is in fact a series of bridges, takes the Seto-Chuo Expressway across the Inland Sea, connecting Okayama Prefecture to Kagawa Prefecture. A series of nine bridges take the Nishiseto Expressway across the Inland Sea from Hiroshima Prefecture to Ehime Prefecture.

About this website

Hello and thanks for reading this page. My name is Timothy and my hobby is in describing places so that I can share the information with the general public. My website has become the go to site for a lot of people including students, teachers, journalists, etc. whenever they seek information on places, particularly those in Malaysia and Singapore. I have been doing this since 5 January 2003, for over twenty years already. You can read about me at Discover Timothy. By now I have compiled information on thousands of places, mostly in Peninsular Malaysia and Singapore, and I continue to add more almost every day. My goal is to describe every street in every town in Malaysia and Singapore.
