President Katsuji Ebisawa was aware of everything."

On Jan. 29, 2001 -- the day before the program was to be aired -- senior NHK officials met with Shinzo Abe, who was then deputy chief Cabinet secretary, and LDP lawmaker Shoichi Nakagawa, Nagai said, quoting his superiors.

Nakagawa, the current trade minister, was then head of a Diet group that was discussing what to do about history textbooks that were beginning to mention wartime atrocities committed by Japan during its aggression in Asia.

Nagai said he was told at the time by a senior NHK broadcasting bureau official, who had just met with Abe and Nakagawa, to immediately alter the program. The LDP pair had reportedly learned about the program's contents before its scheduled broadcast, he added.
