What this Japanese vocabulary test covers
- ✓ Kanji compound meaning and reading recognition
- ✓ On'yomi and kun'yomi reading choice in context
- ✓ Katakana loanwords (外来語) and their real meanings
- ✓ Counter words (助数詞) matched to the right object type
- ✓ Synonyms and near-synonyms in everyday and formal registers
Why Japanese vocabulary is different
Most Japanese words carry more than one pronunciation depending on context. The kanji 生 can be read differently in 生きる, 先生, and 誕生日, and a learner has to recognize the compound as a whole rather than sound out each character. On top of that, Japanese has absorbed thousands of English loanwords into katakana, but many drifted from their original meaning. マンション does not mean mansion, it means a mid-size apartment building, and getting this wrong in the test costs points at exactly the level where it should be easy.
Vocabulary size by CEFR level
These are approximate word counts, not exact thresholds, since active and passive vocabulary differ and everyone's reading habits vary.
- A1 Roughly 800 words, mostly hiragana and katakana, minimal kanji
- A2 Roughly 1,500 words, first 100–150 kanji, common loanwords
- B1 Roughly 3,000 words, everyday counter words, basic idioms
- B2 Roughly 5,000 words, workplace and news vocabulary, four-character idioms
- C1 Roughly 8,000 words, formal and technical kanji compounds
- C2 10,000+ words, including literary, legal, and specialized compounds
How the test checks your vocabulary
Questions place a target word inside a short sentence and ask you to pick the meaning, the correct reading, or the word that best completes the gap. This context-based format mirrors how vocabulary actually gets used, rather than testing isolated flashcard definitions. A B1 question might show a sentence about buying tickets and ask which counter word fits 3 tickets, while a C1 question might ask you to distinguish two near-synonyms for "decide" that carry different levels of formality.
Common vocabulary gaps
Learners often confuse similar-sounding words that differ by a single mora, such as 橋 (bridge) and 箸 (chopsticks), which are both read hashi but written with different kanji and pitch accent. Katakana loanwords cause a separate kind of trouble: アパート means apartment reasonably closely, but バイキング means buffet-style meal, not a Viking, and no amount of English knowledge helps guess that. A third gap shows up around counter words, where learners default to a generic counter instead of learning that flat objects, long objects, and small animals each take a different suffix.
How to improve your Japanese vocabulary
- 1. Learn kanji by compound, not in isolation, so you absorb the reading that actually shows up in real sentences.
- 2. Build a short list of katakana loanwords that changed meaning and review it separately from your regular vocabulary.
- 3. Group counter words by object category (long, flat, small animal, machine) instead of memorizing them one by one.
- 4. Read native sentences and note every word you understood by shape but could not have produced yourself.

Common questions
As a rough guide, A1 needs around 800 words, A2 around 1,500, B1 around 3,000, B2 around 5,000, C1 around 8,000, and C2 exceeds 10,000 including specialized kanji compounds. These are approximate ranges, not fixed thresholds, since real vocabulary knowledge varies by topic and reading habit.
Yes. Many questions show a word in kanji and ask you to identify its meaning or correct reading, since a kanji compound like 図書館 has one meaning but two readings (on'yomi and kun'yomi) depending on context, and confusing them is a common source of errors.
Yes, katakana loanwords such as コンピューター or アルバイト appear from A2 level onward. Some closely resemble their English source words, while others have shifted meaning entirely, so recognizing the difference is tested directly.
Counter words (助数詞) are suffixes attached to numbers depending on what is being counted, such as 本 for long thin objects or 匹 for small animals. They are treated as vocabulary items in the test because choosing the wrong counter changes whether a sentence sounds natural or simply wrong.
At A1, a good portion of vocabulary appears in hiragana or katakana, so it is possible to score reasonably without kanji. From A2 upward, kanji compounds become common enough that skipping kanji study will cap your score well below the level you might otherwise reach.
