All three "Daimajin" movies were made at the same time but released a year apart.
Many of the women seen in the film have black teeth. This was a Japanese tradition known as Ohaguro, and was to signify a woman being married.
Many samurai characters have a top-knot. This hairstyle was known as chonmage. Initially intended to hold samurai helmets steady, over time it became a status symbol.
In terms of genre 'Daimajin' is each a jidaigeki (period drama), chanbara (sword fighting) and kaiju (strange beast) film.
The character referred to as a 'priestess' in the English subtitles, is in fact a miko. This term means 'shrine maiden' and more appropriately reflects her duties within the film.
