Translation guide
The concept of loyalty in Japanese is expressed through words emphasizing devotion, faithfulness, and duty. The most common term is 忠誠 (chuusei), but other words like 忠義 (chuugi) and 誠実 (seijitsu) carry different nuances. Loyalty is often shown through actions and commitment rather than just words.

忠誠 (chuusei) is the general term for loyalty, suitable for most contexts. 忠義 (chuugi) implies a deeper, almost feudal sense of duty and honor, and can sound archaic. 誠実 (seijitsu) focuses on sincerity and faithfulness in personal character, often overlapping with loyalty in relationships.
Directly translating 'loyalty' as 忠誠 in casual conversation may sound overly formal. In everyday situations, describing actions (e.g., いつも味方する 'always take someone's side') is more natural.
She is devoted (loyal) to her family.
