In Japanese 恩返し (on gaeshi) - 'returning a favor' is close, but often implies more transactional. A more descriptive phrase is: 恩に報いる (on ni mukeru) - 'to repay a kindness' or 恩を返す (on o kaesu) - 'to return a favor'.
To repay a kindness, gratitude, or favor received from someone.
Example
"他决定报恩，帮助他的恩人。"
