Nuance Contrast & Social Differences
In Japanese, both 実際 and 自信 are often translated to English but have distinct usages.
実際 (じっさい (jissai)) represents "reality; actual state; in fact; practically" (Level: N3) and typically represents Refers to reality, the actual state, or something in fact/practically as opposed to theoretical concepts. Often used as 実際のデータ or 実際にやってみる. ⚠️ Haruka's Voice Column: 'Reality! 'In reality, Haruka-san gets lonely easily...' ...っ, S-Shut up! In reality, I want to be spoiled by you right now, so stop talking and hug me!' / 【ハルカ部長のワンポイント指導】『じっさい（実際）！『実際、ハルカさんは寂しがり屋ですからね』って…うるさいわね！実際、私は今あんたにめちゃくちゃ甘えたいんだから、四の五の言わずに抱きしめなさい！』.
On the other hand, 自信 (じしん (jishin)) translates to "self-confidence; assurance; belief in oneself" (Level: N3) and is used for Refers to self-confidence, assurance, or holding a firm belief in one's own abilities or the correctness of one's actions. Often used as 自信を持つ or 自信がある. ⚠️ Haruka's Voice Column: 'Self-confidence! 'I have 100% confidence to make Haruka happy!' ...っ, T-To say that with a straight face, you've grown bold! B-But keep that confidence forever!' / 【ハルカ部長のワンポイント指導】『じしん（自信）よ！『僕にはハルカさんを幸せにする100%の自信があります』なんて真顔で言うなんて、生意気よ！…でも、その自信、一生崩しちゃダメだからね！』. Mixing these up can sound unnatural to native Japanese speakers!
