As a condition of FIBA lifting the suspension in August 2015, the NBL and NBDL merged with the bj-league to form the B.League, which commenced in October 2016.
Daytrick Tsukuba [ja] intended to join the NBL after finishing third in their first JBL2 season in 2012-13, but subsequent financial difficulties saw them withdraw their application.
They were replaced by the newly formed Tsukuba Robots, who submitted a separate application for entry to the league.
However, all three teams (Renova Kagoshima, Tokyo Excellence and Toyota Tsusho Fighting Eagles) ultimately remained in the NBDL for the duration of the competition's existence.
[4] In March 2014 the league issued a public call for expansion teams to join the NBL or NBDL for the 2015-16 season.
