It seems Ryotao Sakai was given a stern warning and docked 50% of his pay for the game (about 24,000 yen). The other umps were also given warnings.
Tomoaki Kanemoto skied a ball in the 2nd inning that apparently hit a section of the Kyocera Dome ceiling called the super ring. The rules for the stadium state that balls that hit the super ring are considered in play, but rookie first base ump Ryotaro Sakai (first Ichi-gun game of his career) immediately ruled the ball foul.
The umps ended up convening in the middle of the diamond to discuss the call after there was some question as to whether or not balls that hit the ceiling were indeed foul. After a few minutes the lead up walked over to the microphone and announced that the ball should have been considered in-play but that since play stopped due to the original call, it would be considered a foul ball.
Akinobu Mayumi apparently wasn't happy with that call and rushed out of the dugout to complain.
In the end, the foul call actually helped Kanemoto out since he ended up hitting a home run in that same at bat. Had the play been called properly, Kanemoto maybe gets a double or a triple out of it.
It should also be noted that it was after that Kanemoto's homer that Tony Barnette seemed to fall out of rhythm (he did get out of the inning without any further damage, but fell apart in the 3rd inning). Again, had the play been called properly, the umps and Mayumi don't spent 5-10 minutes talking about the call.
