JLPT N5 vocabulary is the base of Japanese study, but memorizing only translations is not enough to use words reliably in the test room. N5 uses very basic words, yet beginners must handle hiragana reading, katakana spelling, kanji readings, and particles all at once.

This guide explains how to understand N5 vocabulary volume, how to use a vocabulary book, and how to repeat words in context and sound. For the full exam structure and passing criteria, first read JLPT N5 概覽.

Vocabulary volume: 約 800 詞, 無官方清單・估算

JLPT does not provide an official vocabulary, kanji, or grammar list. Therefore, it is not possible to say exactly how many N5 words there are. Based on textbooks and past-exam-style materials, 約 800 詞 is commonly discussed. This is a 無官方清單・估算 figure.

About 100 kanji are also often mentioned, but this is also 無官方清單・估算. In N5, it is better to learn kanji readings and meanings inside basic words instead of analyzing kanji deeply. Dates, people, school, time, place, and direction should be met in writing and sound together.

N5 passing requires an 總分 80, at least 38 in 語言知識・閱讀, and at least 19 in 聽力. Scoring has two sections: the combined 120-point 語言知識・閱讀 section and the 60-point 聽力 section. Vocabulary affects not only word questions but also short reading and listening.

Which words to learn first

Start by grouping words by daily-life themes: numbers, time, weekdays, family, school, food, transportation, location, weather, and shopping. N5 does not test specialized topics, so quick recognition in familiar scenes matters.

Study parts of speech together. A noun, い-adjective, な-adjective, and verb behave differently in sentences. If you memorize only the meaning, similar choices will confuse you. For verbs, check dictionary form, ます form, past form, and negative form in short sentences.

Katakana words can be surprisingly hard for beginners. Even loanwords that feel familiar may have Japanese-style sounds and spelling. If katakana reading is slow, it consumes test time. Read short words aloud and learn common spelling patterns.

How to use a vocabulary book

A vocabulary book is not just a place to collect new words; it is a tool for managing words you need to see again. First check meaning and reading, second read the example sentence, and third hide the translation and recall from Japanese only.

Do not set the daily amount too high. At the entry level, 15-20 new words plus review is more sustainable than 50 new words at once. As the number of words grows, review also grows, so choose a pace you can maintain.

Choose materials with example sentences. Knowing that a word means eat is different from reading it naturally in phrases such as eat breakfast, eat at school, or what will you eat. Reading examples aloud also helps listening. Textbook selection continues in JLPT N5 教材.

Context and spaced repetition

Long-term memory needs context. N5 words look easy, but in real questions, nearby words can feel similar. Compare words in the same group through sentences: time expressions, place expressions, people words, and object names.

Spaced repetition brings a word back just before you forget it. Seeing today's words tomorrow, several days later, and a week later helps memory last. If you keep missing the same word, check whether the reading is wrong, the meaning is mixed with a similar word, or you lack example sentences.

Connect vocabulary to reading and listening. After using a wordbook, read short sentences and check which particles appear with the word. For listening, read examples aloud and use audio when possible. Exam-format usage continues in JLPT N5 歷屆試題.

Commonly difficult word types

Time and date expressions are the first group. Today, tomorrow, yesterday, morning, night, times, minutes, and weekdays appear often in reading and listening. Missing one time expression in listening can make the answer hard to choose.

Location and movement expressions are next: above, below, inside, outside, front, back, right, left, go, come, and return. Learn them with simple pictures or tables when possible. Basic verbs and adjectives are also essential. After learning the meaning, confirm present, past, negative, and polite forms through examples. Use JLPT N5 文法 with vocabulary study.

DAYLAB N5 應用

The DAYLAB JLPT app manages N5 vocabulary through FSRS spaced repetition and shows furigana with example sentences. At first you can reduce the burden with furigana; later you can practice reading only the Japanese spelling. You can check the app on the 首頁, and the full self-study flow continues in JLPT N5 自學.
