50 Japanese Interjections You Should Use: Part2

Yuka

I’ve been working on my aizuchi. What other interjections should I add to sound more natural in Japanese conversation?

Rei

Great progress! Part 2 covers emotion-based interjections — joy, disappointment, relief, and the ones you’ll use when things go wrong. These are essential for everyday conversation!

In Part 2 of our Japanese interjections series, we focus on emotional reactions — the sounds and words that express how you feel in the moment. These are the interjections that bring color and life to your Japanese.

At a Glance: Emotional Interjections

Expressing Joy and Relief

• やった！合格した！— Yes! I passed!
• よかった！無事だった。— Thank goodness! They were safe.
• 最高！— The best! / That’s amazing!
• 嬉しい！— I’m so happy!
• ラッキー！— Lucky! (borrowed from English)

Expressing Disappointment and Mistakes

• 残念！あと少しだったのに。— What a shame! We were so close.
• しまった！忘れてた！— Oh no! I forgot!
• あー、やってしまった。— Ugh, I did it again.
• しくじった。— I blew it / messed up. (casual)
• ついてない。— I’m having bad luck today.

しまった！sounds like a really useful natural reaction. Is it the same as やばい？

Rei

They overlap but have different tones! しまった is classic and formal enough for any situation — ‘I made a mistake.’ やばい is very casual and younger-sounding — ‘this is bad / crazy.’ Use しまった at work; やばい with friends!

Surprise and Shock

• びっくりした！— You scared me! / I was surprised!
• えっ、まじで？— What, seriously?
• 信じられない！— I can’t believe it!
• 本当に？— Really?
• うそでしょ！— No way! You’re joking!

Pain and Discomfort

• 痛い！— Ouch!
• 熱い！— That’s hot! (heat)
• 寒い！— It’s cold! / I’m cold!
• 疲れた〜。— I’m so tired~
• お腹すいた。— I’m hungry.
