Highways of Japan
Japan
has a nationwide system of
national highways
(
一般?道
,
Ippan Kokud?
)
distinct from the
expressways
. The
Ministry of Land, Infrastructure, Transport and Tourism
and other government agencies administer the national highways. Beginning in 1952, Japan classified these as Class 1 or Class 2. Class 1 highways had one- or two-digit numbers, while Class 2 highways had three-digit numbers. For example, routes
1
and
57
were Class 1 highways while
507
(the one with the highest number) was a Class 2 highway.
A 1964 amendment to the governing law resulted in a unification of the classes, which took effect in April of the following year. Highways numbered since that time have had three-digit numbers, so the numbers 58?100, which had so far been unused, remained unused. However, when
Okinawa Prefecture
reverted to Japanese control in 1972, Route 58, with its southern endpoint in Okinawa's capital city of
Naha
, was established. The numbers from 59 to 100 remain unused. Some other numbers have been vacated by the joining or changing of routes: 109 (joined with 108), 110 (renumbered as 48), 111 (renumbered as 45), 214?216 (joined to form 57).
