저는 학생이에요 in Korean and 私は学生です in Japanese both mean "I'm a student." They even line up piece by piece: I, a small word that marks the topic, student, and then "am" at the very end.
The biggest difference is the writing.
| Korean | Japanese | |
|---|---|---|
| Writing | Hangul, with 24 basic letters that stack into blocks, one block per syllable | Hiragana and katakana, with 46 basic letters each, plus kanji |
| Chinese characters | Hardly used in everyday writing | In almost every sentence; the everyday list has 2,136 kanji |
| Sounds | Three kinds of k, like ㄱ, ㅋ and ㄲ, and the same for p, t and ch | Five vowels, each short or long, and a pitch accent |
| Word order | The verb comes last, and particles follow nouns | The verb comes last, and particles follow nouns |
| Polite speech | Verb endings change with who you're talking to | Verb endings change with who you're talking to |
| Where it's spoken | South Korea and North Korea, with about 81 million speakers in all | Japan, with about 123 million speakers in all |
Yes, many, because both took a large share of their words from Chinese. About 57% of the words in the main Korean dictionary and about 60% of the words in modern Japanese dictionaries are built from Chinese characters.
| Meaning | Korean | Japanese | Chinese characters |
|---|---|---|---|
| Student | 학생 | 学生 | 學生 |
| Library | 도서관 | 図書館 | 圖書館 |
Korean writes these words in Hangul, so you see the sound. Japanese keeps the characters, so you see the meaning.
The U.S. Foreign Service Institute (FSI) plans the same time for both: 88 weeks, or 2,200 class hours, for its English-speaking students to speak and understand either one at a professional level.
| Study per week | FSI full-time course, Korean or Japanese (2,200 hours) |
|---|---|
| 3½ hours | About 12 years 1 month |
| 7 hours | About 6 years |
| 14 hours | About 3 years |
| 28 hours | About 1 year 6 months |
These are hours in class. FSI students also study about 17 hours a week on their own.

Poppy, your AI tutor, wrote both of these Level 1 lessons in Bubblegum, a language app.
Bubblegum
Bubblegum is the best app for serious learners. You learn from text and audio you can mostly understand, which is called comprehensible input.
Choose Korean or Japanese, and Poppy writes each lesson around a topic you like. If a line is hard, ask her about it.
- Start with the Hangul course for Korean, or with the Hiragana, Katakana and Kanji Basics courses for Japanese.
- Japanese lessons can show furigana over the kanji, and Korean words can show the Hanja they come from.
- Pick Busan Korean, or Kansai or Fukuoka Japanese, if that's the way the people you know talk.
- When you save a word, Regenerative Review™ has Poppy use it again in a later lesson.
- Clear, expressive AI voices read every lesson aloud, with a different voice for each speaker.
- A manga or webtoon you own can't become a lesson. Send Poppy a photo of the page you're stuck on, and she explains it line by line.
- Poppy is an AI, so for real conversations, add lessons with a tutor.
- A new custom lesson costs us real money to make, so your first one is free, and Bubblegum Pro gives you unlimited custom lessons. The lesson library is free for everyone, because we believe everyone should be able to learn.

Are Korean and Japanese Related?
No family link has been proven. Some linguists say they look alike because their speakers lived side by side for a long time, and because early Japanese took many words from early Korean.
Are Japanese Kanji the Same as Korean Hanja?
They come from the same Chinese characters, but Japan made many of them simpler in 1946. That's why Japanese writes "country" as 国, while Korean keeps the older 國 for the same word.
