J2
In short
J2 is the second tier of professional football in Japan, sitting directly below the J1 League.
In plain words
It is a competitive league where clubs compete for promotion to the top flight. Teams play each other in a round-robin format throughout the season. The top finishers move up to J1, while the bottom teams face relegation.
A simple example
If a club finishes in the top two positions of the J2 table, they earn a spot in the J1 League for the following season.
Why it matters
It serves as the vital bridge between regional football and the elite level of the sport in Japan. It provides a pathway for smaller clubs to achieve national prominence.
Easy to mix up
Do not confuse it with J3, which is the third tier of the Japanese football pyramid.
