Economy of Japan
The Japanese agricultural sector accounts for about 1.4% of the total country's GDP. Only 12% of Japan's land is suitable for cultivation. Due to this lack of arable land, a system of terraces is used to farm in small areas. This results in one of the world's highest levels of crop yields per unit area, with an overall agricultural self-sufficiency rate of about 50% on fewer than 56,000 km² (14 million acres) cultivated.
Kansai region
The Kansai region is a cultural center and the historical heart of Japan, with 11% of the nation's land area and 22,757,897 residents as of 2010. The Osaka Plain with the cities of Osaka and Kyoto forms the core of the region, from there the Kansai area stretches west along the Seto Inland Sea towards Kobe and Himeji and east encompassing Lake Biwa, Japan's largest freshwater lake. In the north, the region is bordered by the Sea of Japan, to the south by the Kii Peninsula and the Pacific Ocean, and to the east by the Ibuki Mountains and Ise Bay. Four of Japan's national parks lie within its borders, in whole or in part. The area also contains six of the seven top prefectures in terms of national treasures. Other geographical features include Amanohashidate in Kyoto Prefecture and Awaji Island in Hyōgo.
