Muzukashii Meaning: Difficult in Japanese, and the Polite No It Hides

The basic meaning: hard to do, hard to understand

Muzukashii covers most of what English means by difficult or hard. It describes tasks, tests, questions, books, kanji, decisions and people who are hard to please. It is an i-adjective, so it changes shape by itself: muzukashii desu is polite present, muzukashikatta desu is polite past, muzukashiku nai desu is the polite negative, and muzukashisō desu means it looks difficult. Before a noun it stays as it is: muzukashii shitsumon, a difficult question.

In casual speech, muzukashii often shrinks to muzui among younger speakers, which you will hear but should not use in polite settings.

Chotto muzukashii desu ne: the soft refusal

The most important thing to know about muzukashii is that it doubles as a polite no. Japanese conversation avoids flat refusals. Instead of dekimasen, I cannot, or dame desu, that is not allowed, people describe the request as difficult and let you draw the conclusion. Sore wa chotto muzukashii desu ne, that is a little difficult, almost always means it is not going to happen. The chotto softens it further, and the ne invites you to agree that it is, sadly, difficult.

Learners often miss this and offer to help with the difficulty, which forces the other person to refuse more directly. The natural response is sō desu ka, wakarimashita, I see, understood, followed by thanks and, if you need it, hoka ni hōhō wa arimasu ka, is there another way?

You can use the same move yourself. When a colleague asks for a favour you cannot do, or a friend suggests a plan you do not want, chotto muzukashii desu with an apologetic tone is far more natural than a direct no. Add a reason with node or kara if you want to soften it more, and offer something else if you can.

Muzukashii versus taihen, mendō, fukuzatsu and kibishii

English uses hard and difficult for several ideas that Japanese separates. Muzukashii is difficulty of skill or understanding: the thing resists your ability. Taihen is difficulty of effort or circumstance: the thing is demanding, tiring or serious. A ten-page report in Japanese is muzukashii if you cannot write it, and taihen if you can but it will take all weekend. Taihen also works as sympathy, taihen desu ne, and as an intensifier, taihen oishii, extremely delicious.

Mendō, often mendōkusai in casual speech, is about bother rather than difficulty: the task is tedious or annoying. Filling in the same form three times is mendō, not muzukashii. Fukuzatsu means complicated, with many interacting parts; fukuzatsu na kimochi is a mixed feeling. Kibishii means strict or severe: a strict teacher, a harsh winter, a tough schedule. Said about a deadline or a budget, kibishii means there is no room, which is another polite way of saying no.

Notice that the words for hard split by what is resisting you: your ability (muzukashii), your energy (taihen, kitsui), your patience (mendō), your understanding (fukuzatsu) or the rules (kibishii). Choosing the right one makes your Japanese sound precise rather than vague.

The opposites: yasashii and kantan

Japanese has two everyday opposites for muzukashii and they are not interchangeable. Kantan (簡単) means simple or straightforward and is the word you want for a task, a recipe, a test or an explanation: kantan na setsumei, a simple explanation. It is a na-adjective, so it takes na before a noun and desu after it.

Yasashii (易しい) means easy in the sense of gentle on the learner: a text written in easy Japanese is yasashii nihongo. The same sound, written 優しい, means kind or gentle about people, and most speakers feel the two as one word with a soft meaning. If you say kono hon wa yasashii, you mean the book is easy to read; if you say ano hito wa yasashii, you mean the person is kind. For the plain opposite of difficult in speech, kantan is safer, and muzukashiku nai is always available.

Muzukashii kao and other set phrases

Muzukashii also appears in a few fixed expressions. Muzukashii kao o suru, to make a difficult face, means to frown or look troubled, and it is what a Japanese person does while thinking about your request just before the soft refusal. Muzukashii hito is a difficult person, one who is hard to please or hard to read. Muzukashii tokoro is a tricky point, and muzukashii jiki is a difficult period, for a company or a family.

If a question is impossible to answer well, muzukashii shitsumon desu ne buys time while you think, much like 'good question' in English.

Answering 'Is Japanese difficult?'

Nihongo wa muzukashii desu ka is a question every learner is asked, often within a minute of meeting someone. It is friendly small talk, not a test. A flat hai, muzukashii desu ends the conversation; a flat iie, kantan desu can sound boastful. The winning shape is contrast: one thing that is hard and one thing you enjoy.

Good specific details are kanji, keigo, particles and listening speed. If you want to be modest, mada mada desu, I still have a long way to go, is the classic response to any compliment that follows.

• 漢字は難しいですが、話すのは楽しいです。Kanji wa muzukashii desu ga, hanasu no wa tanoshii desu. Kanji is hard, but speaking is fun.
• 敬語がまだ難しいです。Keigo ga mada muzukashii desu. Keigo is still difficult for me.
• 発音は難しくないですが、聞き取りが大変です。Hatsuon wa muzukashiku nai desu ga, kikitori ga taihen desu. Pronunciation isn't hard, but listening is tough.
• 難しいですが、毎日少しずつ勉強しています。Muzukashii desu ga, mainichi sukoshi zutsu benkyō shite imasu. It's hard, but I study a little every day.
• まだまだです。Mada mada desu. I still have a long way to go.

Notice the pattern: X wa muzukashii desu ga, Y wa tanoshii desu. Learn one version by heart and you will never be stuck when the question comes.

The kanji 難 and the words around it

The kanji 難 means difficulty, hardship or disaster. Its on reading is nan, and its kun readings include muzuka(shii) and kata(i), as in the suffix -gatai meaning hard to do: wasuregatai, hard to forget, and shinjigatai, hard to believe. Seeing the kanji in compounds will make several useful words stick.

Muzukashii itself is often written in kana in casual text messages, so do not be surprised to see むずかしい as well as 難しい.

The two hinan words sound the same and are easy to confuse in listening. Context nearly always separates them: one appears in news about scandals, the other on earthquake and typhoon announcements.

Common mistakes with muzukashii

The first mistake is taking a refusing muzukashii literally and pushing on. If you hear chotto muzukashii and reply with a plan to make it easier, you have missed the point. Accept it, thank them and move on or ask for alternatives.

The second is using muzukashii for effort. Kyō wa shigoto ga muzukashikatta sounds like your work required skills you lacked; for a long, exhausting day, say taihen datta. The third is the na versus i confusion: muzukashii is an i-adjective, so never say muzukashii na hito. The fourth is over-using muzukashii desu ne as a thoughtful filler; more than once in a conversation and it sounds like dodging.

Finally, remember that you can be gently direct in return. If you genuinely need a yes or no, ask muri desu ka, is it impossible, or dekinai to iu koto desu ka, do you mean it can't be done. Asked politely, these give the other person permission to say what they meant.
