Industrial League managers Makoto Sasaki (Sega Sammy) and Hideichi Kaminaga (Nippon Express) announced their plans to retire.
The media found out about Sasaki's intention to retire after the current season on Saturday (his contract actually runs through to the end of the current season). Sasaki began his career with Sega Sammy as a batting coach in 2006. He was then made manager when Kenta Oshima stepped down in 2008.
Kaminaga told reporters that he was stepping down after his team lost to JR Kyushu on Sunday.
Said Kaminaga, "It would have been great if we could have won this tournament, but I'm grateful to have a team that has allowed me to get to the Inter-City Tournament 10 years in a row. I thought this would be a good time to take the uniform off. I just told the players in the locker room."
Kaminaga took over as manager of Nippon Express in 2000. During that time his team made it to the Inter-City Tournament 10 times and advanced as far as the final four twice (2001 and 2006). Kaminaga has also seen 10 players from his team move on to the NPB.
