Throughout the entire series there are many scenes of female nudity though most aren't in detail. But still, they are there and present through series.

Tons of suggestive dialogue throughout. Lupin himself is quite the flirt, thus there's a lot of flirtatious dialogue.

There's some brief nudity, mostly involving Fujiko. One episode has breast nudity, though its nipple-less.

One episode the male characters are wearing nothing but leaves to cover their genitalia.

The violence in this show is rather tame. There will occasionally be a scene with blood, but most episodes are bloodless.

Gun usage is quite frequent, but most of the time it is just Jigen using his gun on objects rather than people. Sometimes there will be gun fights, but not usually.

This show has a lot of harsh language. Frickin', crap, damn, hell, bastard, ass, and bitch are used frequently. Each episode usually contains most of these swears.
