A man stares at a woman in a tight bikini's boobs

No sex or nudity, but the space woman dresses herself in a bikini when she first comes to Earth, and then she wears an outfit with a really short skirt; there are times that her underwear is revealed at a distance when she turned really fast and the skirt lifted up.

Not that violent. As for gore: While underwater, Zigra used the top of his horn on the back of his head to cut Gamera across the hand and across his stomache in one scene and blood was flowing out.

In the Japanese version, the "D" word was used a few times by adults and the child actors.

No drug usage.

Zigra MIGHT seem a little scary for extremely young audiences. Seeing Gamera get severely cut by Zigra might be scary to very young audiences, also.
