On the Nagano branch evening news program of NHK on February 15th, the announcer Matsuoka Tadayuki made a live report of a local figure factory. In the report, he was in the costume of Barnaby Brooks Jr. ("Tiger & Bunny"). Although the factory produces some figures of anime, the report had nothing to do with Tiger & Bunny. Matsuoka calls himself an Akihabara-type otaku on his official profile. He had once made a live report in Char Aznable's cosplay.

On the nationwide NHK morning program aired on February 4th, another announcer, Ono Fumie, wore a wig of Hatsune Miku when she reported about the worldwide movement of Vocaloid. NHK has uploaded an original song by Miku on Youtube.
