No sex or nudity, save for a few passing references in dialogue: Characters speak about visiting a "whorehouse" a few times. A woman getting a fully clothed massage tells the masseur he's a pervert and not to touch her "there". This is very low key, but a character looks at a woman's leg and non-existent cleavage and gets and nosebleed (symbolizing he's horny). Characters ask each other if they've ever "been with a woman". A character is ambiguos in his sexual tastes and non-graphically talks about watching others have sex. Thugs talk about killing a man and having "fun" with his woman.

Several non-intense stylized sword-fights resulting in deaths, but no blood or cuts are shown, just people being hit with the sword and falling down. Lots of talk about "revenge killing" but also about why it is wrong.

not that I remember, except for references to "whorehouse's". There might be a few sh*ts or d*mns in there.

some characters smoke from long cigarette holders, characters drink sake.

The screen flashes red when someone gets sliced. a few characters are shown lying dead on the ground (no gore is shown).
