Tabe is constantly seen half-naked, only wearing his sumo outfit. Obviously because he's a sumo champion.

Chuck Norris can be seen topless in several occations.

This cartoon mini series has lots of mild cartoon action violence throughout. There are fightings, explosions, bad guys shooting with laser guns, etc.

None.

Besides from a visible smoking pipe in episode 1, there is nothing.

Some of the mild cartoon action violence can be intense for some very young kids.
