1961 MOTHRA

An expedition to an irradiated island brings civilization in contact with a primitive native culture. When one sensationalist entrepreneur tries to exploit the islanders, their ancient deity arises in retaliation. In waters off Infant Island, a presumed uninhabited site for Rolisican atomic tests, the Daini-Gen'you-Maru is caught and run aground in the turbulence of a typhoon. A rescue party following the storm finds four sailors alive and strangely unafflicted with radiation sickness, which they attribute to the juice provided them by island natives. The story is broken by tenacious reporter Zenichiro Fukuda and photographer Michi Hanamura, who infiltrate the hospital examining the survivors. The Rolisican Embassy responds by co-sponsoring a joint Japanese–Rolisican scientific expedition to Infant Island, led by opportunistic gangster Clark Nelson. Also on the expedition are radiation specialist Dr. Harada, linguist/anthropologist Shin'ichi Chūjō, and stowaway reporter Fukuda. Chūjō has studied the cultures of islands in the area and ascertained that one of the key hieroglyphs in their written language, a radiant cross-shaped star, translates as Mothra. There the team discover a vast jungle of mutated flora, a fleeting native tribe, and two young women only twelve inches tall, who save Chujo from being eaten by a vampire plant. The "Shobijin" (small beauties), as Fukuda dubs them, wish their island to be spared further atomic testing. Acknowledging this message, the team returns and conceals these events from the public. https://en.wikipedia.org/wiki/Mothra_(film)
