Yamaguchi Prefecture is located in the westernmost part of Honshu, and is surrounded on three sides by the sea. With the Chugoku mountain range running from East to West, Yamaguchi Prefecture can be broadly divided up into three regions: the Seto Inland Sea area, the inland mountain area, and the Japan Sea coast area.
The population is approximately 1.41 million people (according to a year 2015 census), and the area is approximately 6,100 km2. The prefectural government capital is located in Yamaguchi City.
Yamaguchi Prefecture boasts a mild climate and is largely spared from earthquake, flood and storm damage. It enjoys the reputation of being a very comfortable place to live.
Yamaguchi has approximately 1,500 km of coastline, including the calm Seto Inland Sea National Park dotted with many islands and the wild, rough coast of the Japan Sea at the Kita Nagato Kaigan National Park. There are around 240 islands scattered throughout the coastal and off-shore areas.
The green, mountainous plateau situated at the western edge of the Chugoku Mountain Range comprises the largest Karst plateau and limestone cave in Japan, which together make up the Akiyoshidai National Park. Our prefecture receives many visitors who come to see the changing seasons in the primeval forests and beautiful gorges that make up the Western Chugoku Mountain Range National Park.
