Consequently, densely populated areas have shorter area codes, while less populated areas have longer area codes. For example: 6 xxxx xxxx (Osaka) 75 xxx xxxx (Kyoto) 742 xx xxxx (Nara) 4992 x xxxx (Niijima island, Tokyo pref.) 82486 xxxx (Takano, Hiroshima pref.) 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
