None.

Severe violence, but nothing exceeding a PG-13 or R rating or what would typically be found in an average violent superhero film.

Godzilla's defeats of some of the other monsters are violent (one monster gets impaled, one gets blown up, one stabbed, etc.)

This movies has the second most swearing in a Godzilla movie. The first one being Godzilla King of the Monsters (2019).

Mild language here and there, including 3 or 4 uses of "s**t",And 1 Word Of B**ch

A Man Is Drinking Some Wine

But None thing Else.

Both of Gigan's versions in this movie, especially his later chainsaw version, may be very frightening to younger viewers.
