Learners are often taught to admire the clean, filler-free sentences of a textbook — and then they open their mouths in Japan and freeze, because real speech is full of little sounds that no textbook models. These sounds, the 言いよどみ (iiyodomi, "hesitation words"), are not laziness or error. They are expected: they hold the floor while you think, they cushion a request, and they signal "I'm getting to it." Speech without them sounds clipped, cold, and unnaturally decisive. This page covers the four core fillers — あの(う), えっと/えーと, なんか, and まあ — and, crucially, teaches you to hear the two that moonlight as content words.
あの(う) / そのー: stalling and getting attention
あの(う) (also written あのー) does two jobs. It flags that you're about to speak — a soft "um, excuse me" that gets someone's attention — and it stalls while you assemble a delicate thought. It is the go-to pre-request softener: opening a favor with あのう gives the listener a half-second of warning and makes the ask gentler.
あのう、すみません。
anō, sumimasen
Um, excuse me…
あのう、ちょっとお願いがあるんですが…
anō, chotto o-negai ga aru n desu ga…
Um, I have a small favor to ask…
Its sibling そのー works when you're stalling mid-thought about something already introduced — "er, that thing, um…" — rather than opening fresh.
そのー、それはですね、ちょっと複雑で…
sonō, sore wa desu ne, chotto fukuzatsu de…
Er, well, that's… kind of complicated…
Both are register-flexible: あのう works in polite speech (unlike the buddy-only あのさ on the さ page).
えっと / えーと: searching for the word
えっと (or the drawn-out えーと) is pure word-search — the Japanese "uhh…" you emit while retrieving a name, a number, a fact. Unlike あのう, it isn't aimed at the listener at all; it's the sound of your own mental gears turning.
えっと、名前は…
etto, namae wa…
Uhh, your name is…?
えーと、どこまで話しましたっけ?
ēto, doko made hanashimashita kke?
Umm, where was I…?
Reaching for えーと instead of an English "uh" is one of the fastest ways to stop sounding foreign — the vowel quality alone gives you away otherwise.
なんか: the hedging "like, kinda"
なんか as a filler means "like, sort of, somehow" — it hedges a statement, softening a claim you're not fully committed to or can't quite pin down. It floats loosely, often right before an adjective or a whole clause.
なんか眠い。
nanka nemui
I'm kinda sleepy.
なんか、この店、雰囲気変じゃない?
nanka, kono mise, fun'iki hen ja nai?
Like, this place has kind of a weird vibe, don't you think?
なんか違うんだよね。
nanka chigau n da yo ne
It's somehow just… off, y'know?
Filler なんか vs content 何か "something"
Here is the double life you must learn to hear. The same string なんか is also the indefinite pronoun 何か "something" (see だれか / なにか / どこか). Content 何か is an argument of the verb — a thing you eat, want, or drink — and is usually written in kanji, read nanika:
何か食べたい。
nanika tabetai
I want to eat something.
何か飲みますか。
nanika nomimasu ka
Would you like something to drink?
Compare filler なんか, which is not an argument — it modifies the mood of the whole utterance and can be lifted out without leaving a gap:
なんか食べたい。
nanka tabetai
I kinda want to eat / I feel like eating.
なんか食べたい can mean either "I want to eat something" (content, = 何か) or "I kinda want to eat" (filler) — and only position, intonation, and context disambiguate. Rule of thumb: if you can delete the なんか and the sentence still names everything it needs, it was the filler; if deleting it leaves the verb missing its object, it was the pronoun 何か.
まあ: "well…" and "more or less"
まあ softens and concedes — the spoken shrug that precedes a lukewarm agreement or a "well, if you put it that way…"
まあ、そうだね。
mā, sō da ne
Well… yeah, I guess so.
まあ、いいか。
mā, ii ka
Well, whatever — it's fine, I suppose.
It has a second, related use: estimation, "roughly, more or less," softening a figure or prediction.
まあ、十人ぐらいかな。
mā, jū-nin gurai ka na
Well, ten people or so, I'd say.
Both senses share the core "don't hold me to this exactly" flavor — まあ hedges a judgment just as it hedges a number.
Common mistakes
Falling back on English "uh / um." English filler sounds instantly mark you as foreign, even when your grammar is perfect.
❌ Uh… 名前は… um…
The English fillers break the sound of the sentence. Swap in えーと and あのう and the same hesitation reads as native.
✅ えーと、名前は、あのう…
ēto, namae wa, anō…
Umm, the name is, uh…
Reading filler なんか as "something." Mishearing the hedge as the pronoun garbles the meaning.
❌ なんか違う。(=Something is different.)
Misparsed — here なんか is the hedging filler 'somehow/kinda,' so the sentence means 'it's kinda off,' not 'something is different.' The pronoun reading would need 何か as the subject.
✅ なんか違う。
nanka chigau
It's somehow / kinda off. (filler なんか — 'kinda,' not the pronoun 'something')
Stripping all fillers to sound "correct." Filler-free speech sounds curt and oddly blunt, like you're reading a list at the listener.
❌ すみません。お願いがあります。手伝ってください。
Grammatically fine but clipped and abrupt — with no softening filler it lands like a series of commands.
✅ あのう、すみません、ちょっとお願いがあるんですが…
anō, sumimasen, chotto o-negai ga aru n desu ga…
Um, excuse me — I have a small favor to ask…
Turning なんか into a verbal tic. A hedge in every sentence reads as vague and unsure, the young-speaker stereotype.
❌ なんか、なんか疲れて、なんか帰りたい、なんか。
Over-hedged — piling なんか on every phrase sounds vague and immature, like English 'like, like, like.'
✅ なんか疲れちゃって、もう帰りたいな。
nanka tsukarechatte, mō kaeritai na
I'm kind of worn out — I just want to go home.
Key takeaways
- Fillers are expected, not sloppy: they hold the floor, soften requests, and keep speech from sounding clipped and cold.
- あの(う) stalls and gets attention (a great pre-request softener); そのー stalls mid-thought; えっと/えーと is pure word-search.
- なんか leads a double life: hedging filler "like, kinda, somehow" vs. the indefinite pronoun 何か "something" — tell them apart by whether deleting it leaves a hole.
- まあ spans "well…" (concession) and "roughly" (estimation), both hedging a judgment.
- Use real Japanese fillers, not English "uh/um" — but don't let なんか become a tic.

- さ: Casual Emphasis & RhythmN3 — The casual particle さ leads a double life — mid-sentence it is a floor-holding filler that chops speech into chunks and signals 'wait, I'm not done,' while sentence-finally it lands a breezy, matter-of-fact assertion that is cooler and more offhand than よ.
- 相槌: BackchannelingN4 — This is the token inventory of 相槌 — the うん / はい / ええ / そうですね / なるほど / へえ / たしかに that Japanese listeners emit every few seconds to signal 'I'm following' — with a hard warning that listenership-はい means 'I hear you,' not 'yes, I agree.'
- Connective Openers: じゃあ / では, ところで, そういえば, ちなみにN3 — The little words that open a turn — じゃあ/では, ところで, そういえば, ちなみに, plus the reactive でも / だって / それで / で / ていうか — are discourse signposts that tell the listener how what you're about to say relates to what just came before: pivot, aside, recollection, footnote, objection, or continuation.
