Translation guide
The English word "junction" refers to a point where things join or meet. In Japanese, the translation depends heavily on context: physical intersections (roads, railways), electrical connections, or abstract joining points. This guide covers the most common and useful Japanese expressions for each meaning.
A place where roads, highways, or railway lines meet or cross.
The most common word for a road intersection or crossing. Used for city streets and general road junctions.

That junction has many accidents.
Literally 'branching point'. Used for junctions where a road or railway splits, like a fork or turnout.
