JPmate is a focused JLPT N4 study app for learners who have finished N5 or built the basics of Japanese. Move beyond kana and complete beginner-level Japanese with kanji, essential vocabulary, grammar, short reading, and natural-pace clear listening practice.
WHY JPmate N4
• Built for the N4 exam format. Question types, sections, and timing follow the JLPT structure, so your next-level mock tests feel familiar.
• Explanations in your language. Every answer is explained in English, Korean, Vietnamese, Chinese (Simplified & Traditional), and Burmese — read the why, not just the what.
• Spaced repetition that works. An FSRS-based review schedule resurfaces weak items right before you forget them, helping you strengthen beginner-level skills after N5.
• Listening built in. Natural-pace, clear listening (聴解) practice with hide/show scripts — train your ear, then check yourself.
• Academically grounded. Vocabulary and grammar are checked against authoritative Japanese references and official guidelines-based exam structure.
WHAT'S INSIDE
• N4 vocabulary, grammar, reading (読解), and listening (聴解) questions
• Listening audio practice for natural-pace, clear 聴解 training
• About 300 kanji, about 1,500 words, beginner grammar, and short everyday reading practice
• Full-length mock tests in the JLPT N4 section structure
• Wrong-answer notes that collect everything you missed
• Daily streaks and a study heatmap to keep momentum
• A clean, distraction-free interface in light or dark mode
