What Senka Said (1984)

A small girl's dress is wet so she walks around in her underwear for a few scenes. Her chest is exposed.

A small boy's bottom is briefly shown as he is washing up.

A small girl falls into the river and begins to drown. She flails and screams for help. A small boy tries to rescue her but isn't strong enough. The scene is intense as it seems the girl will die. She is then saved by a person passing through. The girl cries afterwards from the ordeal.
