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
In 2005, one half of Japan's energy was produced from petroleum, a fifth from coal, and 14% from natural gas. Nuclear power in Japan made a quarter of electricity production but due to the Fukushima Daiichi nuclear disaster there has been a large desire to end Japan's nuclear power program. In September 2013, Japan closed its last 50 nuclear power plants nationwide, causing the nation to be nuclear free.
