This last decade has marked the darkest period in Japan basketball history, with the sport divided between two rival men's leagues.

What's more, the Japan Basketball Association was suspended by FIBA, the sport's world governing body, for its lack of governance, between December 2014 and August 2015.

Some people call the period in which there were two men's two circuits — the old-guard NBL (formerly called the JBL) and the upstart bj-league — "Ten lost years."
