Exclusive economic zone of Japan
Japan has the eighth largest Exclusive Economic Zone (EEZ) in the world. The total area of Japan is about 377,973.89 km². Japan's EEZ area is vast and the territorial waters (including: the Seto Inland Sea) and EEZ together is about 4.48 million km².
Water supply and sanitation in Japan
Water use is about 83.5 km3, or 20% of water availability in an average year. However, there are large variations in the utilization rate between years and regions. For example, in the coastal part of the Kantō region that includes Tokyo the utilization rate is over 90% in a dry year. In the relatively dry north of Kyushu it is more than 50%. Of the total use 55.2 km3 was for agriculture, 16.2 km3 for domestic use and 12.1 km3 for industrial use. Despite the introduction of water-saving devices domestic per capita use declined only slightly from 322 liter per capita per day in 2000 to 314 in 2004. Per capita water use thus is slightly lower than in the United States (371 liter in 2005) and more than twice as high as in Germany (122 liter in 2007) or in England (145 liter in 2009).
