Logo (Startup; 1970-2001, Closedown; 1970-2006)
Visuals:
 * Startup: On a sky, we see the flag of Japan waving. It later fades into a satellite dish rotating. A few seconds later, we see the white text NHK zoom in. After the NHK text zooms in, the text "総合テレビジョン" ("General Television") in white appears under it.
 * Closedown: On a sky, we see the flag of Japan waving. It later fades into a live-action model of a globe rotating counterclockwise and zooming in. Once the globe centers on Japan, we see the white text NHK zoom in from Japan. After the NHK text zooms in, the text "総合テレビジョン" ("General Television") in white appears under it. A few seconds after the "General Television" text zooms out, the globe fades out.

Variants:
 * Starting in 1984, the video was re-recorded with videotape compared to film used in the 1970 variant, and the NHK and General Television text now has a black outline. The globe in the closing variant also does not fade out.
 * In 1995, the NHK logo was changed, with three eggs with the letters "NHK" flipping in. The General Television Text is also smaller.

Technique: Live-action.

Audio:
 * Startup: A patriotic fanfare starting with ascending chimes with some "ding-dong" sounds.
 * Closedown: The national anthem of Japan, Kimigayo.
