== The Japanese drama series == 

 I'm confused about the actors for the Japanese drama series. 
 This page conflicts with IMDb, listing a different set of actors for the main roles. 

 Keisuke Tachibana - Kippei Shiina OR Koichi Yamadera 

 Yusuke Ono - Naohito Fujiki OR Hozumi Goda 

 Eiji Kanda - Hideaki Takizawa OR Tomokazu Seki 

 Chikage Kobayakawa - ??? OR Kazuhiko Inoue  

 Who is right?  Were there two live-action series?
