Korean vs Japanese: Which Is Harder for English Speakers?
Same FSI difficulty rating — but what specifically differs?
By US FSI standards, both Korean and Japanese are Category IV (hardest) for English speakers — ~2,200 hours needed.
But Korean speakers learning Japanese (or vice versa) is completely different. Grammar/word order is nearly identical, making them arguably the easiest foreign languages for each other.
Writing System — Most Dramatic Difference
| Factor | Korean | Japanese |
|---|---|---|
| Script types | Hangul only (24 letters) | Hiragana + Katakana + Kanji (3 types) |
| Time to start reading | Hours | Weeks (kana only) |
| Time to full reading | 1-2 weeks | Years (2,136 common Kanji) |
Hangul is considered the world's easiest writing system. Japanese Kanji takes years to achieve reading proficiency.
Pronunciation — Korean Is Harder
Japanese pronunciation is very simple: 5 vowels, consonant+vowel combinations. Korean's 3-way consonant distinction (ㄱ/ㅋ/ㄲ: plain/aspirated/tense) is extremely difficult for foreigners.
Conclusion
For English speakers: Similar, but Japanese is slightly harder due to Kanji. For Korean→Japanese: Very easy if you overcome Kanji. For Japanese→Korean: Pronunciation (tense/aspirated distinction) is hardest.
