If you're just starting out with Japanese, N5 and N4 can look almost identical from the outside — both are labeled "beginner," both test similar categories (vocabulary, grammar, reading, listening), and both feel achievable within a few months of study. The reality is a bit different once you're inside the material.
What N5 actually tests
N5 is designed to certify that you can understand basic Japanese used in everyday situations and classroom settings. Practically, that means:
- Reading simple sentences and short passages written in hiragana, katakana, and basic kanji
- Recognizing around 100 kanji and a core vocabulary of everyday words
- Following slow, clearly-spoken conversations about familiar daily topics
Most learners who've completed a first-semester Japanese course or a few months of consistent self-study land comfortably in N5 territory.
Where N4 actually raises the bar
N4 isn't just "a bit more N5." The vocabulary and kanji count roughly doubles, and — more importantly — the grammar shifts from simple sentence patterns to structures that require you to track more context: te-form connections, potential and volitional forms, plain/casual speech alongside polite speech, and conditional expressions.
The listening section also picks up pace. N5 audio is deliberately slow and simple; N4 starts sounding closer to natural speech, which is often where learners feel their first real wall.
Which one should you start with?
If you're brand new to Japanese, start with N5 material regardless of your long-term goal — even if you're aiming for N2 or N1 eventually, skipping the N5 foundation almost always creates gaps that surface later in more complex grammar. If you've already studied for 6+ months, worked through a beginner textbook, or lived in a Japanese-speaking environment, it's worth taking an N4 practice test cold to see where you actually land before committing months to N5 review you may not need.
The practical takeaway
Don't judge your readiness by level number alone — judge it by whether you can comfortably read a short paragraph with mixed kanji and follow a conversation at natural, non-textbook speed. That's the real dividing line between N5 and N4, more than any single grammar point.
