The scene where the machine is being demonstrated on the elderly invalid man show him naked- his genitals are however blanked out.

The nurse Haruko has unwelcome advances made towards her by the elderly computer hacker.

There is a scene of a young couple in bed together following a night out.

Infrequent profanity. A few uses of "s**t", "a**hole", and one use of "f**k" near the beginning.

A group of people (Haruko's friends/colleagues) go to a kareoke bar and are seen drinking.

Some mild and (mostly) comedic peril, but nothing frightening or intense.
