Below are some other legal ages worthy of note (in Korea):

1) Age of criminal responsibility: 14

2) Age of civil/tort responsibility: 14-15 (according to case law)

3) Age of (sexual) consent: (most of the time) 16

4) Legal drinking age: 20*

5) Minimum driving age: 18

6) Marriageable age: 18

7) Legal working age: 18

8) Minimum (mandatory) enlistment age: 18

9) Voting age: 18

10) Age of candidacy: 25 (lawmaker); 40 (President)
*19 if the year in which you turn 20 has already commenced.
