The directory should be posted on the league website, in English and Japanese, with contact information for all of the agents.
This would let current and prospective players know who are the individuals working on their behalf with the league's teams. And it would help provide much-needed transparency as well.
The well-documented problems the Aomori Wat's have had recently (http://www.japantimes.co.jp/sports/2014/09/10/basketball/bj-league/anatomy-scam-aomori-targeted-fake-agents/) should be a catalyst for the league to let the public know who are the agents, all of them.
Having all of agents' information in one place is a good starting point for the league to keep track of this important issue.
With nonstop growth for a decade now -- and counting -- what with the arrival of the teams in Nagasaki and Ishikawa Prefecture for 2015-16, and more than 80 foreign players, the more information that's posted, the better.
This would improve league operations and give players and coaches a better handle on how things develop, too.
