Japanese vs Korean: which should you learn first?
Both are FSI Category IV — the hardest tier for English speakers, requiring roughly 2,200 hours to professional proficiency. Both have passionate learner communities, rich pop culture, and excellent streaming content. The real question is: what pulls you in?
Follow your passion — but Korean has the lower barrier to entry
Korean's Hangul writing system can be learned in a weekend. Japanese requires mastering three scripts — hiragana, katakana, and 2,000+ kanji — which adds significant early overhead. If you're genuinely torn, Korean is the faster language to get reading in. But if anime and Japanese gaming are your primary motivation, Japanese wins on content depth and comprehensible input resources. Both are equally difficult in the long run.
Japanese vs Korean: the full comparison
Writing systems: the biggest practical difference
Korean uses Hangul — a phonetic alphabet invented in 1443 that can be learned to reading level in 1–3 days. It's one of the most logical writing systems ever created. Once you know Hangul, you can read anything (even if you don't understand the words).
Japanese requires three scripts: hiragana (46 characters), katakana (46 characters), and kanji (2,136 for newspaper literacy, 2,000+ for everyday use). Most learners spend 3–6 months just on the writing system before they can read native content comfortably. This is the single biggest early barrier in Japanese that Korean doesn't have.
Comprehensible input: Japanese has the edge
Comprehensible Japanese on YouTube is one of the best CI resources for any language — graded from absolute beginner to advanced, with clear speech and subtitles. Japanese also has an enormous anime library (much of which is graded for children and therefore easier to comprehend), plus Tadoku graded readers.
Korean CI resources are growing fast — Talk To Me In Korean, Korean Unnie, and the explosion of K-drama content on Netflix provide excellent listening practice. But the structured, graded CI content for Japanese is currently deeper.
Netflix & streaming: Korean content is booming
Squid Game, Crash Landing on You, Extraordinary Attorney Woo, and dozens of other K-dramas have made Korean the most-watched non-English language on Netflix globally. The K-drama format — 16-episode seasons with clear dialogue — is excellent for immersion learning. Japanese anime on Netflix is also abundant, but the speech patterns in anime can be more stylized and less representative of natural spoken Japanese.
