Kiyohara will be acting as an editor for a manga called Danjiri (だんじり). The manga will be about a weak high school baseball team that is trying to make it to the Summer Koshien; the manager of the team will also be loosely based on Kiyohara.
A popular business book written by Natsumi Iwasaki, titled "If a high school female supporter read Drucker's 'The Practice of Management'" (もし高校野球の女子マネージャーがドラッカーの『マネジメント』を読んだら), has been picked up by NHK to become an anime. The series will be 10 episodes long and will begin airing at 10:55pm on NHK sometime in March, 2011.
Note: translating the Japanese term マネージャー (read "manager") is a little difficult because it actually doesn't have the same meaning as the English term manager. While supporter may not be the ideal translation for マネージャー, it's the best that I can come up with for the time being. That said, I have also seen the title of this book translated as "If the Girl Manager of a High School Baseball Team Read Drucker's 'The Practice of Management'".
