Sponichi posted a friendly conversation between manager Koji Yamamoto and general pitching coach Osamu Higashio.  Of particular interest, is the staring line-up Yamamoto mentioned.

CF - Hisayoshi Chono
2B - Takashi Toritani (Kazuo Matsui)
SS - Hayato Sakamoto
C - Shinnosuke Abe
LF - Seiichi Uchikawa
RF - Yoshio Itoi
3B - Nobuhiro Matsuda
1B - Atsunori Inaba
DH - Sho Nakata

With regards to the offense, Yamamoto and Higashio are quoted as saying the following:

Yamamoto: In terms of the line-up, there is no need to rely on individual strengths.  There is no top or bottom  [of the order].  There is no easy out, every hitter should be able to hit.  It should be a group effort to score one run. ...

Higashio: It should go back-and-forth between left-handed and right-handed hitters.  That will make it difficult for opponents when they go to the bullpen.

Yamamoto: Exactly.  During international tournaments, there are many cases where the bottom of the order will create scoring opportunities for the top of the line-up.  In that sense, the lead-off hitter could become the clean-up hitter and the number three hitter could become the lead-off hitter.

Higashio: Hitters that are willing to do anything can become a pain for pitchers.

Yamamoto: Abe can bunt.  If we need a run and we have runners on first and second and no out, I will turn to the bunt play.  I am sure even he will be thinking like that.  We will definitely do bunt practices during mini-camp in Miyazaki.  And we have a hitter with experience in Uchikawa batting fifth.

The two also briefly spoke about the pitching staff and possible effects of not having any MLB players on the roster.
