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:

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 in 1972, its telephone numbers were squeezed between Miyazaki (98x) and Kagoshima (99x) and begin with 988, 989, and 980.
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,

7442 x xxxx Kashihara (Nara prefecture)
7444 x xxxx Sakurai
74452 xxxx Takatori
74454 xxxx Asuka etc.
became:

744 2x xxxx Kashihara
744 4x xxxx Sakurai
744 52 xxxx Takatori
744 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.




Area code as local brand naming



After entering the 2010s, local products and events have begun using names which come from the area code.
0465net (Odawara, Kanagawa)
0428 T-shirt (Ome, Tokyo)
028 Market (Utsunomiya, Tochigi)
028 Machinaka (Inner-City) Wi-Fi (Utsunomiya, Tochigi)
Bar 053 (Hamamatsu, Shizuoka)
