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.
Telephone numbers in Japan
Geographic numbers are nine digits long, including the area code, but not including the leading zero. Consequently, densely populated areas have shorter area codes, while less populated areas have longer area codes. For example:Area codes increase from north to south; Sapporo in Hokkaidō (the northernmost prefecture) has 11, and Setouchi's 99-73 is far to the south in Kagoshima. When the telephone system was devised, Okinawa was still under U.S. occupation, so when it was returned to Japan in 1972, its telephone numbers were squeezed between Miyazaki (98x) and Kagoshima (99x) and begin with 988, 989, and 980.
