# Liste der Nationalstraßen in Japan

Dies ist eine Liste der japanischen Nationalstraßen (jap. 一般国道, ippan kokudō).

## Geschichte

Die Nationalstraßen wurden am 4. Dezember 1952 durch das Dōro-hō (道路法, „Straßengesetz“) eingeführt und sind Fernstraßen der Zentralregierung. Dabei wurden Nationalstraßen 1. Ordnung (一級国道, ikkyū kokudō) mit den Nr. 1 bis 40 festgelegt. Mit einem weiteren Gesetz vom 18. Mai 1953 erfolgte die Festlegung der Nationalstraßen 2. Ordnung (二級国道, nikyū kokudō). Diese gingen von 101 bis 244. Die Lücke erklärt sich dadurch, dass man die Nummern 41 bis 100 für weitere Nationalstraßen 1. Ordnung freihielt. Ab 1956 erfolgten erste Änderungen. Dabei wurden Straßen 2. Ordnung zu welcher 1. Ordnung (z. B. 155 in 41) umgenummert; sowie weitere Straßen 2. Ordnung festgelegt. Teilweise wurden die entstehenden Lücken erneut benutzt (z. B. Nationalstraße 155). Mit Revision des Gesetzes 1965 wurde diese Klassifizierung aufgehoben, wobei die Straßen jedoch ihre Nummern behielten. 1970 kamen Nr. 272–328 hinzu, 1972 Nr. 58 und Nr. 329–332, 1975 Nr. 333–390, 1982 Nr. 391–449 und 1993 Nr. 450–507. Mit Ausnahme von Nationalstraße 58 sind daher alle Nationalstraßen unter 100 frühere Nationalstraßen 1. Ordnung und bei Einführung neuer Nationalstraßen wurden die Nummern hochgezählt, so dass es keine Nationalstraßen 59 bis 100 gibt. Nationalstraße 58 bildet es Ausnahme, da diese nach der Rückgabe Okinawas an Japan aus dem durch die US-Verwaltung für Truppentransporte eingerichteten Highway No.1 gebildet wurde, der zur Hauptfernverkehrsstraße der Insel wurde.
