How to Say What Are You Doing in Japanese: Natural Phrases

The most natural way to say “What are you doing?” in Japanese is 何してるの？ /nani ɕiteɾɯ no/ with friends, family, or someone you know well. For a polite situation, say 何をしていますか？ /nani o ɕite imasɯ ka/. The key is choosing the right speech level, because the same question can feel friendly, curious, demanding, or intrusive depending on your relationship and tone.

Japanese has about 123 million first-language speakers according to Ethnologue, and everyday conversation relies heavily on context. A short question such as 何してる？ /nani ɕiteɾɯ/ can be completely natural in a text from a close friend, but too direct when speaking to a manager or a new acquaintance.

Before asking someone what they are doing, make sure you know whether you are on casual terms. If you are still unsure, begin with a polite greeting from our guide to how to say hello in Japanese, then use the polite version below.

The essential Japanese phrases

何してるの？

何してるの？ /nani ɕiteɾɯ no/ is the best everyday choice for “What are you doing?” It sounds natural with friends, classmates, siblings, a partner, or colleagues you know well.

The phrase is a shortened form of 何をしているの？ /nani o ɕite iɾɯ no/. Japanese speakers routinely contract している /ɕite iɾɯ/, meaning “is doing,” to してる /ɕiteɾɯ/ in informal speech.

The final の /no/ is not required, but it adds a soft, question-like feeling. Without it, 何してる？ /nani ɕiteɾɯ/ is shorter and can sound more like a quick text message.

何してる？

Use 何してる？ /nani ɕiteɾɯ/ when you want a brief, casual check-in. It is especially common in chats, voice messages, and calls between people who already speak informally.

A message such as 今何してる？ /ima nani ɕiteɾɯ/ often means more than a factual question. It can imply “Are you free to talk?” or “Do you want to do something?” The answer tells the other person whether a conversation or invitation is welcome.

Do not use this clipped form with your professor, a customer, or a senior colleague unless they have explicitly invited casual speech. Japanese politeness is not only about word choice. It also depends on age, role, workplace hierarchy, and how the other person speaks to you.

今何してるの？

今何してるの？ /ima nani ɕiteɾɯ no/ means “What are you doing now?” The word 今 /ima/ means “now,” so it makes the timing explicit.

Use it when you are about to call, want to invite someone out, or are simply checking in during a chat. It is warmer than a bare question when paired with context.

In the example, 暇 /hima/ means “free” or “not busy.” This is a useful word for social planning, but be careful not to translate every English phrase word for word. Japanese speakers often state their availability indirectly.

何をしていますか？

何をしていますか？ /nani o ɕite imasɯ ka/ is the polite standard phrase. Use it with a teacher, supervisor, customer, older person, or someone you have just met.

It is grammatically complete: 何 /nani/ means “what,” を /o/ marks the object, and しています /ɕite imasɯ/ is the polite ongoing form of “do.” In real speech, the particle を /o/ is often audible but lightly pronounced.

This form can ask about the present moment, but it also works for habits when a time phrase is added. 週末は何をしていますか？ /ɕɯːmatsɯ wa nani o ɕite imasɯ ka/ asks what someone generally does on weekends.

Makino and Tsutsui’s A Dictionary of Basic Japanese Grammar explains why forms built with ている /te iɾɯ/ are central to describing ongoing actions and states. English learners often expect one Japanese form to map neatly onto one English tense, but context decides whether the meaning is “are doing,” “do regularly,” or “have been doing.”

Why a direct question can feel different in Japanese

In English, “What are you doing?” can be neutral. In Japanese, 何してるの？ /nani ɕiteɾɯ no/ can be neutral too, but the tone shifts quickly if it is sent repeatedly, asked with suspicion, or used toward someone who expects formal language.

The National Institute for Japanese Language and Linguistics studies naturally occurring Japanese interaction through conversation corpora. Those conversations show a key reality for learners: people rarely speak in isolated textbook sentences. They soften questions, give a reason for asking, and react to the answer.

For example, compare these messages:

• 何してる？ /nani ɕiteɾɯ/ : What are you doing?
• 今何してる？ ちょっと聞きたいことがあるんだけど。 /ima nani ɕiteɾɯ tɕotto kiki tai koto ga aɾɯ n da kedo/ : What are you doing now? I have something I want to ask you.
• 今、お時間大丈夫ですか？ /ima otɕikan daijɔːbɯ desɯ ka/ : Do you have time right now?

The last option does not literally ask what the person is doing. It asks whether they have time, which is often the more considerate question in a professional or formal setting.

Sachiko Ide’s work on Japanese politeness highlights the role of social expectations and appropriate positioning in interaction. That is why choosing 何をしていますか？ /nani o ɕite imasɯ ka/ over 何してる？ /nani ɕiteɾɯ/ is not merely a grammar exercise. It signals how you place yourself relative to the listener.

Better alternatives for real situations

Sometimes “What are you doing?” is not the best question. Choose an alternative based on what you actually need to know.

Asking whether someone is free

Say 今、暇？ /ima hima/ to a close friend. It means “Are you free now?” and is often more useful when you want to meet, call, or play a game.

For a polite version, say 今、お時間大丈夫ですか？ /ima otɕikan daijɔːbɯ desɯ ka/. Literally, it asks whether their time is okay, but naturally it means “Is now a good time?” or “Do you have a moment?”

Asking about work or study

Ask 何の仕事をしていますか？ /nan no ɕigoto o ɕite imasɯ ka/ for “What kind of work do you do?” This is appropriate in a polite getting-to-know-you conversation.

To ask “What are you studying?” say 何を勉強していますか？ /nani o beŋkʲoː ɕite imasɯ ka/. Do not use the short casual form unless the relationship is clearly casual.

Asking what someone is up to

どうしてる？ /doː ɕiteɾɯ/ is a casual “How have you been?” or “What have you been up to?” It is broader than 何してる？ /nani ɕiteɾɯ/ and does not necessarily ask about the current moment.

When reconnecting with someone after a while, this can sound more natural and less abrupt. Pair it with a greeting, especially if you have not talked recently.

Useful answers to “What are you doing?”

Being able to ask the question is only half the interaction. Here are natural short replies.

The sentence 特に何もしてない /tokɯ ni nani mo ɕitenai/ is particularly useful. It means “I’m not doing anything in particular,” and it can subtly show that you may be available.

If you are busy, a friendly answer can preserve the conversation: 今ちょっと忙しいけど、あとで連絡するね。 /ima tɕotto isoɡaɕiː kedo ato de ɾenɾakɯ sɯɾɯ ne/ means “I’m a little busy now, but I’ll contact you later.”

Pronunciation: make the rhythm sound natural

Japanese is mora-timed, which means each beat has a relatively even length. 何してるの /nani ɕiteɾɯ no/ has seven morae: na-ni-shi-te-ru-no. Avoid rushing the final るの /ɾɯ no/ into one vague sound.

The polite phrase 何をしていますか /nani o ɕite imasɯ ka/ also has clear beats. Do not swallow を /o/ or compress している /ɕite iɾɯ/ into an English-style stressed syllable pattern.

For a broader foundation in rhythm, sounds, and pitch patterns, see our Japanese pronunciation guide. Japanese pronunciation is usually predictable from spelling, but rhythm matters as much as individual consonants and vowels.

Learn the phrase through scenes, not isolated drills

This question appears constantly in Japanese dramas, anime, and everyday messaging scenes because it creates interaction quickly. Notice what happens after it: does the speaker want to make plans, tease a friend, check availability, or confront someone?

That context teaches you the social meaning that a literal translation misses. A character saying 何してるの？ /nani ɕiteɾɯ no/ to a close friend may sound playful, while the same line from an angry parent can sound like an accusation.

Build a small practice set around realistic exchanges:

1. Hear 今何してるの？ /ima nani ɕiteɾɯ no/.
2. Identify whether the scene is casual, affectionate, or tense.
3. Repeat the line with the speaker’s rhythm.
4. Answer aloud with one of the short replies above.
5. Change the context and choose the polite version when needed.

The phrase to remember is simple: 何してるの？ /nani ɕiteɾɯ no/ for people close to you, and 何をしていますか？ /nani o ɕite imasɯ ka/ when politeness matters. Learn both, then let the relationship and situation choose the one you say.
