Thirty-eight-year-old Yuji Iiyama is planning to retire after the season.
Iiyama hurt his left biceps femoris before opening day and started the season at Ni-gun. He made it to Ichi-gun on August 9, but when the team was eliminated from a first place finish, the Nippon Ham Fighters started giving younger players more playing time. Iiyama has been at Ni-gun ever since he was taken off the active roster on September 1.

The Fighters held a press conference for Iiyama at their office in Toyohira-ku, Sapporo.
[UPDATE 10/3 @ 11:20pm]
Iiyama played in his retirement game on October 3 against Orix at Sapporo Dome. He entered the game as a defensive replacement at short in the eighth inning and helped turn a double play. During his at bat in the bottom-half of the inning, he flied out to left.
After the game, teammates tossed Iiyama into the air seven times.
