Consequently, densely populated areas have shorter area codes, while less populated areas have longer area codes. For example: 06 xxxx xxxx (Osaka) 075 xxx xxxx (Kyoto) 0742 xx xxxx (Nara) 04992 x xxxx (Niijima island, Tokyo pref.) 082486 xxxx (Takano, Hiroshima pref.) Area codes increase from north to south; Sapporo in Hokkaido (the northernmost prefecture) has 011, and Setouchi-cho's '''09973''' is far to the south in Kagoshima. When the telephone system was devised, Okinawa was still under US Occupation , so when it was returned to Japan in 1972, its telephone numbers were squeezed between Miyazaki (098x) and Kagoshima (099x), and begin with 0988, 0989, and 0980. During the 1990s, when plans were being drawn up to amalgamate mid-sized cities and towns into larger municipalities, telephone numbering systems were merged in advance. For example, 07442 x xxxx Kashihara (Nara prefecture) 07444 x xxxx Sakurai 074452 xxxx Takatori 074454 xxxx Asuka etc. became: 0744 2x xxxx Kashihara 0744 4x xxxx Sakurai 0744 52 xxxx Takatori 0744 54 xxxx Asuka etc. Many of these towns have in fact refused to merge, leaving callers with more digits to dial when making local calls. This is partially balanced by not having to dial an area code for the neighboring city. SEE ALSO
