These two beautiful posters were made for the film Zoku-zoku-Kindan no suna: Akai pantsu, which translates to something about “prohibited man’s sands” something or other, but which seems to be known in English as Woman Diver’s Beach: Red Pants. The movie is third in a series starring Kyoko Izumi, and as you might guess it deals with an ama—a female diver for clams, treasure, and other valuable submerged items. The plot is a bit convoluted, but basically a villager gets into a fight and accidentally kills a man only to have the man’s fiancée show up and, affected by the villager’s anguish over his deed, begin to feel sorry for him, then begin to feel affection him. There’s much more to the film—for example, both the villager and fiancée are the focus of unrequited love from other quarters, and this will lead to serious complications and even some gunplay, but what you get for the most part is a star-crossed love story. The “red pants” reference, by the way, is for the color of shorts the fiancée wears. We have a poster for a couple of the other films in this franchise and you’ll be seeing those soon. This one premiered in Japan today in 1959.
You can't have one without the other.
