Nam-a Pictures Co., Ltd.

Background

Logo (July 17, 1981)
Visuals: On a background of waves crashing over rocks (which looks very similar to Toei's logo), the words 南亞振興株式會社 作品 (meaning "produced by Nam-a Pictures Co., Ltd.") fade in and then fade out after several seconds.

Technique: The name of the company fades in and out of view.

Audio: The sound of the waves breaking.

Availability: Can be seen preceding the company's 1981 film Suddenly in the Dark.
