was re-designated as Government Highway 1 during the civil administration of the island, but the US military's vehicles still took priority over the local Okinawan driving community, who were not allowed to pass US military convoys and vehicles. After the return of the Ryukyu Islands from the United States to Japan on 15 May 1972, the aforementioned highways were all re-designated as a part of National Route 58. It remains the only Japanese national highway to be given a two-digit number following the reclassification of the Primary and Secondary National Highways as the General National Highways in 1965.

After the 730 switch, Okinawa joined the rest of Japan in driving on the left in accordance to the Vienna Convention on Road Traffic.
