ドキドキ, ワクワク, イライラ — Expressing Feelings with Mimetic Words

Nervous? ドキドキ. Excited? ワクワク. Irritated? イライラ. Master these emotion words and your Japanese feelings vocabulary levels up instantly.

In the introductory article, we mentioned 擬情語 (gijou-go) — mimetic words specifically for describing inner feelings. Japanese is incredibly rich when it comes to expressing emotions: there are multiple words just for "nervous," "happy," or "angry," each with distinctly different nuances. This article groups the most useful emotion words by feeling so you can learn them all in one go.

Nervousness & Excitement

WordReadingMeaningNuance
ドキドキどきどきHeart poundingNervous, excited, or having a crush — works for all
ワクワクわくわくEager anticipationPurely positive excitement, like a kid waiting for Christmas
ハラハラはらはらOn the edge of your seatWorrying about someone else; common when watching sports
ソワソワそわそわRestless, fidgetyCan't sit still; anxiously waiting

ドキドキ is the most versatile one — it works for nervousness, crushes, and fear. Context makes it clear:

試験の前はドキドキする。 → I get nervous before exams.

好きな人に会うとドキドキする。 → My heart pounds when I see the person I like.

ワクワク is always positive anticipation — never used for fear:

旅行の前日はワクワクして眠れなかった。 → I was so excited the night before the trip that I couldn't sleep.

ハラハラ is for watching someone else and worrying on their behalf:

子供が木に登るのをハラハラしながら見ていた。 → I watched my kid climb a tree with my heart in my throat.

ソワソワ leans toward a "can't sit still" feeling, like waiting for important news:

結果が気になってソワソワしている。 → I'm restless because I can't stop thinking about the results.

Anger & Frustration

WordReadingMeaningNuance
イライラいらいらIrritated, frustratedThe most common word for "annoyed"
ムカムカむかむかNauseous / furiousPhysical nausea or psychological anger
カリカリかりかりCranky, snappyGetting upset over little things
プンプンぷんぷんFuming (mildly)Lighter anger, slightly cute-sounding

イライラ is the go-to word for everyday annoyance:

電車が遅れてイライラする。 → The train is late and it's so annoying.

ムカムカ has a dual meaning — it can be physical nausea or psychological fury:

食べすぎてムカムカする。 → I ate too much and feel nauseous.

あの態度にムカムカした。 → That attitude made me furious.

カリカリ describes the state of snapping at every little thing:

上司は朝からカリカリしている。 → The boss has been cranky since morning.

プンプン is lighter in tone and often used to describe children or women pouting:

彼女はプンプン怒っている。 → She's fuming (in a huffy sort of way).

Happiness & Joy

WordReadingMeaningNuance
ニコニコにこにこSmiling warmlyA warm, friendly smile
ウキウキうきうきIn high spiritsCheerful, feeling like humming a tune
ルンルンるんるんWalking on airSo happy your steps feel light
ホッほっRelievedA sigh of relief after worry passes

The difference between ニコニコ and ウキウキ: ニコニコ focuses on facial expression, while ウキウキ focuses on mood:

プレゼントをもらってニコニコしている。 → Got a present and is all smiles.

デートの日はウキウキする。 → I'm in such high spirits on date days.

ルンルン is a step beyond ウキウキ — you can picture someone practically skipping:

合格の知らせを聞いてルンルンで帰った。 → Heard I passed and went home practically skipping with joy.

ホッ is not a repeating type — it's a single relieved sigh:

無事に終わってホッとした。 → It ended safely and I breathed a sigh of relief.

Sadness & Dejection

WordReadingMeaningNuance
シクシクしくしくSobbing quietlyCrying softly, tears flowing silently
メソメソめそめそCrying weaklyWhimpering, with a hint of "stop crying already"
しょんぼりしょんぼりDejected, crestfallenNot necessarily crying, just visibly down

シクシク is quiet, gentle crying:

子供がシクシク泣いている。 → The child is crying quietly.

メソメソ carries a slightly negative judgment, implying "toughen up":

メソメソしないで、元気を出して。 → Stop whimpering — cheer up!

しょんぼり is the only one written in hiragana (not a repeating type), expressing visible dejection:

テストに落ちてしょんぼりしている。 → Failed the test and is looking dejected.

Grammar Patterns: Three Key Usages

Emotion mimetic words most commonly appear in three patterns:

Practice Quiz

Show Answer
  • ドキドキ → Heart pounding — can be nervousness, fear, a crush, or excitement (both positive and negative)
  • ワクワク → Eager anticipation — only for positive excitement (looking forward to a trip, a gift, etc.)

Quick rule: if it's "scared-nervous," use ドキドキ; if it's "can't-wait-happy," use ワクワク.

Q2. Translate this into Japanese: "That attitude really annoyed me."

Show Answer

あの態度にイライラする。 or あの態度にムカムカした。

イライラ leans toward ongoing frustration, while ムカムカ leans toward a sudden flash of anger. Both work.

Show Answer
  • しょんぼり → Dejected, crestfallen — not necessarily crying, just visibly down

しょんぼり is a state of low spirits; メソメソ is active (weak) crying that others find tiresome.
