First Study provides Japanese vocabulary divided by JLPT level (N5~N1).
To make it easier for anyone to study every day, we provide Japanese words divided into the number of words that can be memorized per day.
Additionally, you can check the Japanese words you studied that day through a test.

Have you just started learning Japanese? Don’t know how to read Chinese characters yet?
Don't worry. First Study shows you the pronunciation of Japanese kanji in hiragana/katakana, and also supports Japanese audio.
Even if you have no prior knowledge of Japanese, you can study Japanese by listening and watching.

Studying words is all about repetition! You can review the Japanese words you studied by unit, JLPT level, or entire unit.
Frequently misspelled words can be reviewed more frequently. The more you use the app, the more personalized your vocabulary becomes.

All words are installed with the app when you download it. Therefore, you can study Japanese anytime, anywhere.

Let's study Japanese first.

Subscription payment
- Remove ads from the app for the price of a cup of coffee each month and study with all examples.

Voice Assistant Issues

JLPT Japanese, for now, provides Japanese audio using the TTS (Text To Speech) engine.
There is an issue with Japanese voice support not being properly supported on some Androids (Galaxy). For smooth voice support, we recommend downloading Speech Recognition & Synthesis and Japanese voice data.

For more information, see Settings in the app > Pronunciation section > "Is your pronunciation not sounding normal?" Please click the arrow button next to it to confirm.

app notifies on regular basis to encourage the user to study (i don't think you can swipe away to ignore, which is good) it lacks details e.g. irregular verbs requiring appropriate conjugation, which is a shame (e.g. 帰る) also more example sentences would be nice for words with a number of meanings. the same goes for multiple pronunciation for the same kanji ( 七).

안녕하세요. 리뷰를 남겨주셔서 정말 감사합니다. 한국 사람을 위한 앱이여서 한글로 답변드립니다. (혹시 외국분이시라면 죄송합니다.) 제가 만든 앱이 누군가의 일본어 공부에 조금이나마 도움이 되고 있는거 같아 너무너무 기쁘네요. 앞으로 더욱 공부하기 편한 일본어 단어 앱이 되도록 노력하겠습니다. 남겨주신 소중한 의견인 상세 설명, 더 많은 예제, 여러 발음을 가진 단어에 대한 설명등을 추가할 수 있는지 알아보도록 하겠습니다. 리뷰를 남겨주셔서 다시 한번 감사드립니다. 오늘도 좋은 하루되시고 새해 복 많이 받으세요.
