About Kotoba Forest: JLPT Vocabulary
New: JLPT Forest — take a vocabulary diagnosis, pick your exam date and goal, and the words you don't know yet become your own forest, with a daily plant-and-water plan that runs all the way to exam day. Make kanji practice and Japanese vocabulary review part of a forest that grows with you. Study 10,000 JLPT N5–N1 words with spaced repetition, native audio, example sentences, mock tests, and playful daily review. BEGINNER FOREST: MASTER KANA FIRST — FREE Brand new to Japanese? Start in the free Beginner Forest and learn kana from zero. Learn hiragana and katakana letter by letter (including dakuon and yōon), then drill kana combos with listening quizzes until reading feels automatic. Hiragana × katakana contrast pairs train both scripts side by side, and starter words written entirely in kana bridge you into JLPT N5 vocabulary — hear it, read it, then meet the kanji later. KANJI PRACTICE WITH REAL VOCABULARY Practice kanji through the words you actually need for Japanese and the JLPT. Each word card combines kana, kanji, meaning, an example sentence, and Japanese audio. Review readings and meanings, revisit mistakes, and use the Kanji mini-game and themed Kanji Forest for focused kanji practice. SPACED REPETITION THAT BUILDS LONG-TERM MEMORY Kotoba Forest uses a seven-stage spaced repetition system (SRS). Plant a new word, water it through scheduled reviews, and help it grow into an evergreen word. Unlike ordinary flashcards that repeat everything at the same pace, spaced repetition brings each word back just before you forget it. Correct answers move vocabulary forward; forgotten words return for more practice at the right time. JLPT N5–N1 VOCABULARY AND MOCK TESTS Choose your target level from N5, N4, N3, N2, or N1. Browse level-based Japanese vocabulary, take timed JLPT mock tests, and review your score history. Kotoba Forest doubles as a Japanese vocabulary builder that keeps every word tied to your JLPT level. When you reach your goal, create a shareable score card to mark your progress. A STUDY FOREST THAT CHANGES AS YOU LEARN Every review helps your trees grow. Collect word fruit, unlock animal companions, and build a forest that reflects the work you have completed. Daily check-ins, mystery chests, streaks, accuracy, and vocabulary statistics make progress easy to see. ANIMAL MINI-GAMES Turn review into short challenges: ・Spelling ・Rock-paper-scissors ・Cloze questions ・Dictation ・Sentence building ・Kanji practice MORE JAPANESE TO EXPLORE VIP themed forests add Kanji, Idioms, Loanwords, Homophones, and advanced vocabulary. Downloaded content remains available for offline browsing and review. The interface supports English, Traditional and Simplified Chinese, Korean, Thai, Vietnamese, and Indonesian. WHO IS KOTOBA FOREST FOR? ・Complete beginners — learn hiragana and katakana from zero in the free Beginner Forest ・JLPT learners from N5 to N1 ・Beginners building a daily Japanese habit ・Learners who want structured kanji practice without endless drilling ・People who remember more when progress feels visual and playful FAQ Does Kotoba Forest teach kanji? Yes. Kanji appears in word cards, example sentences, review activities, a Kanji mini-game, and a dedicated themed forest. Can I study offline? Previously downloaded vocabulary can be browsed and reviewed without a connection. Is this only for JLPT test preparation? No. The JLPT structure organizes the vocabulary, while SRS, audio, examples, and mini-games support everyday Japanese learning. Kotoba Forest is a Japanese learning app built for short daily sessions rather than long cram sessions. A few focused minutes each day can grow both your forest and your Japanese vocabulary.
