反省する (hansei suru) implies self-reflection with a forward-looking intention to improve, similar to 'repent'. 後悔する (kōkai suru) is simply feeling regret about the past, without necessarily changing behavior. Use 反省する when you want to convey a resolve to do better.
Directly translating 'repent' as 悔いる (kuiru) is possible but sounds archaic or literary. In modern conversation, use 反省する or 悔い改める depending on context.
Literally 'change one's heart', meaning to turn over a new leaf or reform oneself. Stronger than just regret.
