Japanese Hesitation: Using ええと, あの, and なんか to Express Uncertainty
Learn to hesitate naturally in Japanese with fillers like ええと, あの, and なんか. Practice softening statements and expressing uncertainty in conversation.

In Japanese conversation, hesitation is not a sign of weakness; it is a key tool for maintaining politeness and natural flow. Unlike direct expressions of doubt or certainty, hesitation markers like ええと (eeto), あの (ano), and なんか (nanka) allow you to pause, think, or soften your statement without committing to a clear position. This lesson focuses on these fillers and phrases such as よくわからない (yoku wakaranai) and 場合による (baai ni yoru) to help you sound more natural and considerate when you are unsure. You will learn when to use each expression and how they differ from outright doubt or certainty.
By the end, you can…
- use common Japanese hesitation markers like ええと and あの to pause naturally.
- express uncertainty with phrases such as よくわからない and 場合による.
- soften statements using なんか and ちょっと to avoid sounding abrupt.

Useful pattern
Hesitation markers in Japanese often come at the beginning of a sentence. For example, ええと、場合によるかもしれません (ēto, baai ni yoru kamoshiremasen) means 'Well, it might depend.' Adding かもしれません (kamoshiremasen) makes it more tentative. Similarly, なんか、よくわからない (nanka, yoku wakaranai) means 'I'm kind of not sure.' These patterns allow you to express uncertainty without being vague or impolite.
When to use it
Use ええと when you need time to think, especially in formal situations. あの is more casual and can be used to get someone's attention or when you are hesitant to speak. なんか is very casual and often used among friends to soften statements. Avoid using なんか in formal writing or speeches. For uncertainty, よくわからない is direct but can be softened with ちょっと, as in ちょっとよくわからない (chotto yoku wakaranai), meaning 'I'm not quite sure.'
Listen to each line, then take one part and reply out loud.
ええと、この問題は場合によると思います。
Well, I think this problem depends on the situation.Ēto, kono mondai wa baai ni yoru to omoimasu.あの、ちょっとよくわからないんですが、もう一度説明してもらえますか。
Um, I'm not quite sure, could you explain again?Ano, chotto yoku wakaranai n desu ga, mō ichido setsumei shite moraemasu ka.なんか、難しいですよね。私もよくわからないです。
It's kind of difficult, isn't it? I'm not sure either.Nanka, muzukashii desu ne. Watashi mo yoku wakaranai desu.そうですね。ええと、先生に聞いてみましょうか。
That's right. Well, shall we try asking the teacher?Sō desu ne. Ēto, sensei ni kiite mimashō ka.A little context goes a long way
In Japanese, hesitation markers are not just fillers; they signal that you are considering the other person's feelings and avoiding imposition. Using ええと or あの can make you sound more thoughtful and polite. However, overusing them may make you seem indecisive. In formal contexts, it's better to use ええと rather than なんか, which is casual. Also, direct expressions like よくわからない can be softened with ちょっと to maintain harmony.
One thing to watch for
Using なんか in formal situations, such as in a business meeting, because it is casual and can sound unprofessional.
Try this instead: In formal contexts, use ええと or あの instead. For example, say ええと、よくわからないのですが (Ēto, yoku wakaranai no desu ga) rather than なんか、よくわからない (Nanka, yoku wakaranai).
