Is Japanese Hard to Learn? What's Hard, What's Easy, and How Long It Takes

Is Japanese hard to learn?

Yes, for English speakers Japanese is one of the harder languages to learn. The US Foreign Service Institute (FSI) puts it in its hardest group and estimates 88 weeks, or 2,200 class hours, to reach a high level of speaking and listening. But the first steps are gentler than that sounds: the sounds are fairly simple for English speakers, there are no genders, plurals or articles, and you can learn the kana in weeks.

How hard is Japanese? What the FSI says

The FSI trains US government staff, including diplomats, and sorts languages into categories by how long English speakers usually take to learn them. These figures are from its Foreign Language Training page, last modified on 21 January 2026.

The FSI calls category IV languages "exceptionally difficult for native English speakers". It lists five languages there and doesn't rank them against each other.

Four details change how to read the number:

• The target is high. It is an integrated speaking and listening score of 3 on the Interagency Language Roundtable scale, not "can order dinner".
• It is classroom time. A typical FSI week is 23 hours in class and 17 of self-study, which the 2,200 hours do not include.
• It is an average. Actual time varies with natural ability, earlier language learning and time in class.
• It is for full-time students. Most people learn part-time.

That is only a rough scale: it counts class hours, not the self-study the FSI adds, and it is for a very high target. Your own goal is probably smaller.

What is hard about Japanese

Kanji

Kanji are the Chinese characters Japanese uses alongside its two kana scripts, and for most learners they're the biggest single task. Japan's official list of everyday characters, the jōyō kanji, has 2,136 of them. Most kanji also have more than one reading: a character can have several readings borrowed from Chinese, and one or more native Japanese readings. The right reading depends on the word. See 漢字 (かんじ, kanji, “kanji”) in what is kanji.

Politeness

Japanese has a grammatical system for politeness and formality, with different verb forms and special vocabulary depending on who is speaking, who is listening and who is being talked about. 敬語 (けいご, keigo, “honorific”) is the word for it. Understanding a shop assistant or a boss means meeting more than one style.

Word order and particles

Japanese puts the verb at the end of the sentence, and small words called 助詞 (じょし, joshi, “particle”) mark each part's job. English does the opposite, so early sentences feel back to front. Counting uses special counter words too: see Japanese counters.

Listening

In a 2011 study of seven languages, speakers read the same texts aloud. Japanese came out at 7.84 syllables per second, about the same as Spanish at 7.82, and carried the least information in each syllable. So speech can sound fast to a beginner. The JLPT's own level descriptions show the gap: N5 listening is about short conversations "spoken slowly", while N3 is the first level at "near-natural speed".

Pitch and homophones

Japanese has a pitch accent: in standard (Tokyo) Japanese, はし can mean "chopsticks" or "bridge", and only the pitch differs. Some dialects use the reverse pattern.

What is easy about Japanese

• The sounds. Japanese has five vowels, each short or long, and relatively simple syllables.
• The kana. Hiragana and katakana each have 46 basic characters. How long they take depends on you; our own estimate is one to three weeks for each script, at 15 to 30 minutes a day. See how long it takes to learn hiragana and katakana.
• No genders, plurals or articles. Japanese nouns have no grammatical number or gender, and there are no articles.
• Verbs don't change for who does the action. The form doesn't depend on whether the subject is I, you or they.
• Very few irregular verbs. The two main ones are する (suru, “to do”) and 来る (くる, kuru, “to come (spatially or temporally)”).
• Loanwords. Japanese takes in many words from other languages, written in katakana, so some words will look familiar. See what is katakana.

How long does it take to learn Japanese? Realistic milestones

The FSI gives one target, a score of 3 on its scale. Smaller steps help more. The JLPT, Japan's main proficiency test, describes five levels, N5 to N1, which work as milestones. It publishes no study hours for the current test.

Here is what we can put times to:

• Kana: our own estimate is one to three weeks per script, at 15 to 30 minutes a day (details).
• N5: about 150 hours, the JLPT's own figure for the old Level 4 that N5 matches. That is roughly 11 to 21 weeks at one to two hours a day. Third-party estimates for full-time students in Japan are higher: 250 to 600 hours for N5 and 400 to 1,000 for N4 (how long to study for JLPT N5).
• N3 to N1: we found no published hours. The FSI's 2,200 class hours is the only official guide for a very high level.

Where to start

Start with the kana: they are the quickest visible progress you can make.

Questions about learning Japanese

How long does it actually take to learn Japanese?

It takes about 2,200 class hours, or 88 weeks of full-time study, to reach a score of 3 on the ILR scale for speaking and listening, according to the FSI. Simpler goals need far less: the kana take one to three weeks each, by our estimate, and JLPT N5 about 150 hours.

How long does it really take to learn Japanese?

It depends on your goal, your hours and how well you review. For N5, about 150 hours is the JLPT's own figure for the old Level 4. For a very high level, the FSI says 2,200 class hours.

Is Japanese the hardest language to learn?

No single language is the hardest, but Japanese is in the hardest FSI group for English speakers. The group also holds Arabic, Mandarin, Cantonese and Korean, and the FSI does not rank them within it. Difficulty also depends on the languages you know.

What is the top 3 hardest language to learn?

There is no official top three. The FSI's hardest category lists Arabic, Cantonese, Mandarin, Japanese and Korean, all at 88 weeks.

What is the #1 hardest language?

No source names one hardest language: the FSI's hardest category has five, with the same estimate.

Is Japanese harder than Mandarin?

By the FSI's estimate they are equally hard for English speakers: both are in category IV, at 88 weeks. The difficulties differ. Mandarin is a tone language, while Japanese has a pitch accent, three scripts and a system of politeness. Kanji are Chinese characters, so people who read Chinese may find them familiar.

What is the #1 easiest language to learn?

For English speakers, no one language is officially the easiest. The FSI's easiest group lists Danish, Dutch, Norwegian, Portuguese, Romanian, Swedish and Italian at 24 weeks each, with French and Spanish at 30.

What is the #1 most learned language?

English is the most studied language on Duolingo, then Spanish and French, according to its 2025 report. Japanese was fourth, ahead of German. That counts Duolingo users only.

What are 10 Japanese words?

Ten useful Japanese words to start with are こんにちは, ありがとう, はい, いいえ, 水, 猫, 先生, 友達, 学校 and 好き:

What is "I love you" in Japanese?

The strong way to say "I love you" in Japanese is 愛してる (aishiteru), from 愛 (あい, ai, “love”). In everyday life people more often say 好き (suki), "I like you" or "I'm fond of you", even for love. I love you in Japanese covers it in full.

What does "I suki you" mean?

"I suki you" isn't Japanese. It mixes the English "I" and "you" with 好き (suki), "liking", and people write it as a joke, or by mistake, for "I like you". A Japanese speaker would say 好き, or 好きです to be polite.

How do you say what the f*** in Japanese?

Japanese has crude phrases, but there is no single fixed translation, and it's not a good place to start. For a safe "seriously?", casual speakers say まじ (maji, “serious”) (まじ), meaning serious or not joking, or ask 本当？ ("really?"). Learn polite Japanese first.
