 | | 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. |
 | | Other numbers are 11 digits long, such as mobile numbers, which have either the 090 or 080 prefixes followed by eight digits. |
 | | Especially during the 1990s, as plans were being drawn up to amalgamate mid-sized cities and towns into larger municipalities, telephone numbering systems were merged in advance. |
