Korean vs Japanese vs Chinese: Which Should You Learn First?
Korean is the fastest to start: Hangul is a 24-letter phonetic alphabet you can read in a weekend, while Japanese and Chinese both require years of character memorization before basic literacy. Grammatically, Korean and Japanese are near-twins — same word order, same particle logic — while Chinese sits closer to English, minus conjugation but plus four tones that change a word's entire meaning.
Every "easiest language" ranking treats Korean, Japanese, and Chinese like three flavors of the same difficulty. They are not. They fail you in different places, at different speeds, for different reasons — and the one that wrecks a Chinese learner (tones) barely exists for a Korean learner, while the one that wrecks a Japanese learner (kanji) is a non-issue in Korean.
Here's the actual breakdown, not the vibes-based one, plus the question that matters more than any of it: which one do you already want to be good at.
The writing system is the real fork in the road
This is where the three languages split hardest, and it's not close. Hangul is a true alphabet — 24 letters, invented in 1443 specifically to be learnable fast, no memorization of thousands of symbols required. Japanese runs two phonetic scripts (hiragana and katakana, about two weeks each) on top of roughly 2,000 daily-use kanji borrowed from Chinese. Chinese skips the phonetic step entirely — Mandarin has no alphabet at all, just thousands of characters you learn one at a time.
| Language | Writing system | Realistic time to basic literacy |
|---|---|---|
| Korean | Hangul — 24-letter phonetic alphabet | A weekend to read, a few months to read fast |
| Japanese | Hiragana + katakana (phonetic) plus ~2,000 jōyō kanji | Kana in 2 weeks; kanji takes 2–3 years of steady study |
| Chinese (Mandarin) | Hanzi only — no phonetic alphabet | ~2,500 characters, roughly 2–3 years for comfortable reading |
Grammar: Korean and Japanese are basically cousins
If you've studied Japanese, Korean grammar will feel like déjà vu, and vice versa. Both are SOV (subject-object-verb), both are verb-final, and both use particles glued onto nouns instead of fixed word order to show who's doing what. Korean sentence structure and Japanese sentence structure are close enough that the particle logic transfers almost line for line — 은/는 and は, 이/가 and が, 을/를 and を are doing the same job.
저는 학교에 가요.
jeo-neun hak-gyo-e ga-yo.
I go to school. (literally: I-topic school-to go)
Verb-final, particle-marked — nearly a 1:1 structural match with Japanese.
밥 먹었어요?
bap meo-geo-sseo-yo?
Did you eat? (literally: rice ate?)
Subject and object both dropped — normal in Korean and Japanese, jarring if you're coming from English or Chinese.
Chinese grammar, meanwhile, is the odd one out in a way that actually helps English speakers: Mandarin is SVO like English, has no verb conjugation, no grammatical gender, and no honorific verb swaps to memorize. What it charges you instead is tone. Mandarin has four of them, and they're not decoration — 妈 (mā, mom), 麻 (má, hemp), 马 (mǎ, horse), and 骂 (mà, scold) are four completely different words that happen to share a syllable. Korean and Japanese have no lexical tone at all.
Forget the difficulty ranking — pick by what you can't stop consuming
Here's my actual opinion, and it's the one thing every ranking article skips: difficulty rankings are close to useless for predicting who finishes. The person who picks "easiest" and doesn't care about the content quits at month three, right when the material gets boring. The person who picks the "hardest" one but is obsessed with the shows, music, or people who speak it keeps going through the boring month because they want the next episode, the next lyric, the next conversation.
Which one you learn first quietly discounts the other two
This part rarely makes the rankings, but it's the most practical fact in this whole comparison: your first language changes the cost of the second and third. Learn Korean first and Japanese gets noticeably cheaper — the grammar transfers directly, and Sino-Korean vocabulary (roughly 60% of the language) shares roots with Sino-Japanese words, so words like 약속 (yak-sok, promise) show up sounding almost identical in Japanese. Learn Chinese first and you get less grammar transfer into Korean or Japanese, but you get a massive head start reading kanji and Hanja, since both borrowed their characters from Chinese in the first place.
요즘 일본어도 공부한다고 들었어요.

Heard you've been studying Japanese too, these days.
네, 근데 한국어 덕분에 훨씬 쉬워요.
ne, geun-de han-gu-geo deok-bun-e hwol-ssin swi-wo-yo.
Yeah, but it's way easier thanks to Korean.
한자어 때문이죠? 약속 같은 단어는 일본어랑 거의 똑같아요.
han-ja-eo ttae-mun-i-jyo? yak-sok ga-teun dan-eo-neun il-bon-eo-rang geo-ui ttok-ga-ta-yo.
It's the Sino-Korean words, right? Words like 'yaksok' (promise) are almost identical in Japanese.

Total cheat code.
그러니까 순서가 중요한 거예요. 먼저 배운 언어가 다음 걸 더 쉽게 만들어줘요.
geu-reo-ni-kka sun-seo-ga jung-yo-han geo-ye-yo. meon-jeo bae-un eon-eo-ga da-eum geol deo swip-ge man-deu-reo-jwo-yo.
That's why the order matters. The language you learn first makes the next one easier.
None of that is a reason to study all three at once — most people who try end up mixing particles, borrowing the wrong honorific, or stalling on all three instead of finishing one. Pick the language you actually want to read, watch, and talk in first. If that's Korean, that's the entire premise behind Seoli's story-driven method: you learn 약속 because you want to know if Eden keeps the promise, not because a flashcard app told you to.
Frequently asked questions
Is Korean easier than Japanese?
To start, yes — Hangul reads in a weekend, while Japanese needs kana plus roughly 2,000 kanji for adult literacy. Past the alphabet stage, they're close in overall difficulty, since Korean and Japanese grammar transfer almost directly into each other.
Which language is hardest: Korean, Japanese, or Chinese?
It depends which skill you're weighing. For reading, Japanese usually ranks hardest because it juggles three scripts at once. For grammar, Chinese is friendliest to English speakers structurally, but its four tones make speaking and listening genuinely difficult in a way Korean and Japanese simply aren't.
Does learning Korean help with Japanese or Chinese later?
Yes, unevenly. Korean's SOV grammar and particle system transfer almost directly to Japanese. Its large Sino-Korean vocabulary also helps you recognize Chinese-character-based words in Japanese kanji and, to a smaller degree, Mandarin hanzi — even though everyday Korean no longer writes in Hanja.
Should I learn Korean, Japanese, and Chinese at the same time?
Most people shouldn't. The vocabulary overlap between Korean and Japanese is a gift early on and a source of mix-ups later — you'll swap particles or reach for the wrong word. Get one to a comfortable intermediate level first, then layer in the second.
Is Chinese grammar really easier than Korean grammar?
In some ways, yes — Mandarin has no verb conjugation, no particles, and word order close to English's. What it trades away is tone: mix up 妈 (mā) and 骂 (mà) and you've said "mom" instead of "scold." Korean has zero tones but a real conjugation and particle system to learn instead.
