One very undetailed topless scene.

EXTREME graphic violence throughout the entire film. This film has incredibly realistic and truly graphic violence and the film's violence includes body parts expanding, organs being expelled, showers of gore raining all over the place, and many more.

The main character Kenshiro is incredibly violent and relentlessly brutal. He fights enemies by poking their pressure points and the foes can be seen expanding to ridiculous proportions and then exploding into a thousand pieces like if they were balloons, and even if the most graphic parts are generally censored, all of these instances are clearly visible nonetheless and they're very, VERY gory. This is clearly nothing compared to the anime series, and it's very realistic and disturbing.

The second one flies into the air and hits some rubble head-first.

All of the description listed here occurs in the first act. There are numerous other moments of graphic violence in the film, and they're as gruesome and disturbingly violent as what happens before.

(In order to provide parents with the information they need to decide which kids should watch a film, consider -- instead of describing the complete sequence of events -- just providing a summary of the amount and type of violence that occurs. Previous contents here have been moved to the spoilers section.)

Large amounts of gore and blood. Heads are constantly exploding (sometimes entire bodies explode), men are sliced up, and blood splatters all over. The footage often gets blurry and psychedelic during very graphic moments in the US release, but what happens is still very visible, and is super-violent and gruesome.

The very beginning of the movie portrays the effects of a nuclear explosion with people's skin melting and their eyeballs falling out.

Sh*t is used a few times, little else (in the japanese version), however.

None.

While I wouldn't consider this frightening, it is very violent and intense. Many people are killed in extremely graphic fashion even though some of it is covered with a filter, but the scenes are still visible.
