How long does it take to learn Japanese?

Japanese sits in the current NFATC Category IV at 2,200 class hours to an integrated ILR 3 in speaking and listening, tied with the other four languages in that group. Model v2 adds no Japanese-only surcharge.

The usual two warnings, which matter more here than anywhere:

Those are classroom hours, not app minutes. The current NFATC page describes an intensive schedule of 23 class hours and 17 self-study hours in a typical week. Fifteen minutes of tapping is a different activity.

This is a high oral target, not conversational. The official endpoint is an integrated ILR 3 in speaking and listening. Treating it as roughly C1 is our planning assumption, not an official CEFR crosswalk.

The three writing systems

This is where Japanese earns its reputation, and it is worth being precise about why — the usual "it has 2,000 characters" undersells the actual problem.

Hiragana and katakana are two syllabaries of about 46 characters each. They are genuinely easy: a focused week gets you both. Everyone starts here and everyone finishes this part.

Kanji is the wall. Around 2,136 characters in the jōyō set, which newspapers assume. That alone is comparable to Chinese.

The part that makes it harder than Chinese: most kanji have multiple readings. A Chinese character has essentially one pronunciation. A Japanese kanji typically carries a native reading and one or more Chinese-derived readings, and which one applies depends on the compound it sits in. 生 has well over a dozen readings in common use.

So you are not learning 2,000 characters. You are learning 2,000 characters times the readings that matter for each, plus which reading fires in which word. That multiplication is the honest answer to "why is Japanese harder than Chinese".

Grammar: unfamiliar, not complicated

Japanese grammar is regularly called hard, and it is not — it is foreign, which feels the same from the inside but behaves differently.

What is genuinely simple: no grammatical gender, no plural agreement, no articles, and two irregular verbs in the entire language. Conjugation is remarkably regular once you see the pattern.

What is disorienting: the verb comes last, so you cannot begin translating until the sentence ends. Particles mark what each phrase is doing rather than word order. And the subject is dropped constantly — Japanese sentences routinely omit what English would consider essential.

The result is that you cannot get by translating from English. You have to build sentences the Japanese way, and that shift takes far longer than memorising rules.

Keigo, and where intermediate learners stall

Japanese encodes the relationship between speaker, listener, and subject in the grammar. The same thought takes different verb forms depending on relative status. This is keigo, and it is not optional politeness — it is structural.

Beginners can safely ignore it. It becomes unavoidable around B1, and it is a large part of the gap between a competent speaker and a comfortable one, especially at work. It is also nearly impossible to acquire from an app: nothing corrects you for using the wrong register with the wrong person.

What is actually easier than you expect

Pronunciation. A small sound inventory, almost all of it comfortable for English speakers. Japanese has pitch accent rather than tone — it distinguishes a handful of pairs like hashi (chopsticks / bridge) — but getting it wrong usually leaves you understood. Compare Mandarin, where a wrong tone is a different word entirely.

Loanwords. Katakana is full of English: コンピューター, レストラン, テーブル. Thousands of words arrive nearly free, and the meanings have drifted less often than people warn.

What each level actually costs

If you already speak Chinese

The shared characters create genuine orthographic overlap, and this model assigns an estimated discount for it. The current NFATC page does not publish a literacy sub-budget, so the model cannot claim what share of the 2,200-hour oral benchmark a Chinese reader has already completed.

The limits are worth stating. Readings do not transfer at all: knowing how to say a character in Mandarin tells you nothing about its Japanese readings. Meanings have drifted in plenty of cases. And Japanese grammar shares nothing with Chinese grammar — Chinese is analytic and SVO, Japanese is agglutinative and SOV. You get the writing system at a discount and pay full price for everything else.

If you already speak Korean

This model assigns its largest typological-transfer coefficient to this pair. The languages are unrelated by descent and look different on the page; the coefficient is an estimate rather than a measured hour saving.

What transfers is the machinery: nearly identical sentence structure, particles doing the same jobs, agglutinative verb endings, topic marking, and parallel honorific systems. A Korean speaker learning Japanese is not rebuilding their sense of how a sentence works. Both languages also carry a large shared layer of Chinese-derived vocabulary, so a great many words are recognisable.

You still pay in full for kanji — Korean stopped using Chinese characters in daily writing.

What actually works

• Kana first, in the first week. Everything else assumes them, and romaji becomes a crutch that gets expensive to remove.
• Kanji by component, not by rote. They are built from a few hundred repeating parts. Learners who see the system get through the second thousand far faster than the first.
• Learn readings inside words, not in isolation. A kanji's reading list is meaningless out of context; the compound is the unit worth memorising.
• Get keigo corrected by a person, and start before you feel ready. It is the clearest thing an app cannot teach you, and habits formed wrong are expensive to unlearn.
• Expect the intermediate plateau to be long. Between "textbook Japanese" and "native material" there is a wide gap, and the only way across is a lot of input slightly above your level.
