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.
Economy of Japan
Japan has the highest ratio of public debt to GDP of any developed nation. However, the national debt is predominantly owned by Japanese nationals. The Japanese economy faces considerable challenges posed by a declining population. Statistics showed an official decline for the first time in 2015, while projections suggest that it will continue to fall from 127 million down to below 100 million by the middle of the 21st century.
