Japanese or Korean: Which Is Easier, and Why the Ranking Says Neither

Written Aug 12, 2026Sources re-read Sep 24, 2026

The short answer

By the only published ranking, neither: the US Foreign Service Institute places Japanese and Korean in the same band, Category IV, described as "super-hard languages", at 88 weeks and 2,200 class hours for its own full-time students (read 24 September 2026). Anybody telling you one is clearly easier is working from personal experience rather than from a source.

What is true, and more useful, is that they put their difficulty in opposite places. Korean is harder at the start and Japanese is harder in the middle, which means the honest question is not which is easier overall but which kind of hard you would rather meet first.

What the ranking actually says

The FSI sorts languages by how long its own students take to reach a professional speaking and listening standard, and publishes four bands. Category I is 24 to 30 weeks and 552 to 690 class hours for languages close to English. Category II is about 36 weeks and 828 class hours. Category III is about 44 weeks and 1,012 class hours, described as hard languages. Category IV is 88 weeks and 2,200 class hours, and its list is Arabic, Cantonese, Mandarin, Japanese and Korean.

Two caveats, because this figure gets misused constantly. It describes full-time classroom training — the FSI's page describes a typical week as 23 hours per week in class and 17 hours of self-study — and it is aimed at a professional working standard rather than at reading a manga. It is a ratio, not a timetable, and the ratio here says the two languages are treated as equivalent.

Where Korean is harder

The first month. Korean's writing system is a genuinely small alphabet, learnable in days, and that is often quoted as proof it is the easier language — but what follows the alphabet is a sound system that is unkind to English ears.

Korean distinguishes consonants in ways English does not mark at all, and those distinctions change meaning. Sounds also change depending on what sits beside them, so a written syllable is not always pronounced as its letters suggest. A beginner can read Korean aloud within a week and be understood poorly for a long time after that.

Its politeness system is also front-loaded: speech levels are attached to verb endings from the first sentences you learn, so the social dimension arrives immediately rather than gradually.

Where Japanese is harder

The middle years, and the reason is entirely the writing system. Japanese mixes three scripts in ordinary sentences, and the third of them — kanji — carries characters with more than one reading, chosen by the word rather than by the character.

That is a cost that never arrives as a single wall. It arrives as thousands of small associations spread over years, which is why Japanese is described as long rather than steep. The jōyō list, notified by the Japanese Cabinet on 30 November 2010 as a guide for kanji use in writing modern Japanese in general social life, is the usual reference point — and it is a guide, so real text hands you characters outside it regularly.

Japanese pronunciation, by contrast, is comparatively forgiving: a small sound inventory, few sounds absent from English, and words written in kana pronounced as they are written.

More than most language pairs. Both put the verb at the end, both use particles to mark the role of a phrase rather than relying on word order, both encode social relationships in the grammar, and both share a large layer of vocabulary borrowed historically from Chinese.

That last point has a practical consequence: whichever you learn second is meaningfully easier than it would have been first, because the grammatical instincts transfer and a good deal of vocabulary rhymes. Nobody should choose based on this — you will not finish the first one in time for it to matter — but it is a real consolation.

The first month, side by side

If you want the comparison in the form that actually affects your decision:

Reading aloud on day seven. Korean, comfortably. Its alphabet is small and regular; Japanese needs two syllabaries and then keeps going.
Being understood on day thirty. Japanese, usually. Its sound inventory is friendlier to an English speaker's mouth.
Reading a shop sign in month three. Korean, because there is nothing else to learn about the script.
Reading a newspaper in year three. Korean again, for the same reason. Japanese's kanji cost does not stop.
Sounding polite without thinking. Neither, and both will embarrass you at some point.

So how should you actually choose

By what you want to consume or who you want to talk to, and by nothing else. Motivation is the only variable that reliably predicts whether somebody is still studying in two years, and both of these languages are long enough that motivation is the binding constraint rather than difficulty.

If you are genuinely torn, spend a fortnight on each writing system before deciding. Two weeks of hiragana costs almost nothing and tells you more about whether you will enjoy Japanese than any comparison article — including this one. The method for that fortnight is in which Japanese alphabet to learn first.

If you pick Japanese

The route is the same one this site maps: kana in a fortnight, katakana immediately after, grammar and kanji together from week three, listening as soon as there is a commute to fill, and speaking earlier than feels comfortable. The whole sequence, with what each tool actually covers, is in the best way to learn Japanese, square by square.

What matters most on the first day is not the choice between two languages. It is whether you can arrange to touch one of them most days for several years, which is the real difficulty rating and the one nobody publishes.

Choosing between them

Is Japanese or Korean harder to learn?

The Foreign Service Institute puts both in its hardest band, Category IV, at 88 weeks and 2,200 class hours for its own full-time students, so no published source separates them. The practical difference is where the difficulty sits: Korean is harder in the first months because of its sound system, Japanese is harder for years because of kanji.

Is Korean easier than Japanese because of the alphabet?

The alphabet is easier and the pronunciation is not. Korean's writing system can be learned in days, but its consonant distinctions and sound changes are difficult for English speakers and take much longer to master than reading the letters does. Japanese has the reverse profile: harder script, friendlier sounds.

Does learning Japanese help with Korean?

Yes, more than most language pairs. Both put the verb last, both use particles for grammatical roles, both encode politeness in the verb, and both share a large layer of vocabulary borrowed historically from Chinese. Whichever you learn second will be noticeably faster than the first.

Which should I learn first?

The one whose books, shows, music or people you actually want, because motivation decides this and difficulty does not separate them. If you cannot choose, spend two weeks learning hiragana — it is cheap, fast and tells you more about whether Japanese suits you than any article can.
