Need to define consent here.

For example, this graphic seems to imply the age of consent in Japan is 13. While that is the age in certain specific situations, it is normally 18, which would make Japan blue, not red.

Likewise in New Zealand, the normal age of consent is 16, but a person under 16 may consent in some circumstances; contrarily, in some circumstances, the age is 18, not 16.

There is no single age of consent in these two countries (the two I am most familiar with), and I would wager this is the case for most countries.
