Here is the link of the 2009 NPB schedule (of special events).
And
here is the link of a translated version of the page by Google.
(but it has several wrong translations. For example, "PERTH" is wrong and "Pacific league" is right. "Se" means "Central league".)
I hope these pages can help you to know the schedule or the climax series(playoffs).
By the way, well, actually I doubt you can get a ticket of the climax series. It will be hard to get one (especially Hanshin's one... -_-; )
So good luck!!
