B League
In short
The B League is the second-tier professional basketball league in Japan.
In plain words
It is a competitive league for basketball teams across the country. It sits just below the top-level B.League Division 1. Teams compete to win promotion and trophies.
A simple example
A team playing in Division 2 works hard throughout the season to earn enough points to move up to Division 1 next year.
Why it matters
It provides a pathway for smaller cities to host professional sports. It also helps grow the popularity of basketball throughout Japan.
Easy to mix up
Do not confuse it with the NBA or other international basketball leagues.
