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 ¡ª the old-guard NBL (formerly called the JBL) and the upstart bj-league ¡ª ¡°Ten lost years.¡±
