Read full descriptionHide full description
Read your way to Japanese fluency. NihonGO Dokusho is a story reader built for intermediate learners: real, natural Japanese โ and every word, kanji, or grammar point you don't know is one tap from its card. โโ READ โโ Original stories in natural Japanese, written for learners who've finished a beginner course. Turn furigana on or off. Turn per-sentence English on or off. Open a word-by-word breakdown behind any sentence. Three text sizes, plus day and night themes. Every chapter and scene is titled in English, so you always know exactly where you are in the story. โโ TAP โโ Every underlined word is a card, drawn from a library of 7,700 vocabulary words, 2,200 kanji and 600 grammar points. In vocabulary mode, tap a word for its meaning, reading, and example sentences โ which link on to their own cards. Switch to kanji mode to open any character with its stroke order, radicals, and a memory hint. Grammar points open from the sentence breakdown. Conjugated words resolve to their dictionary form automatically. โโ LISTEN โโ Every sentence and every scene is read aloud in a clear, natural-sounding Japanese voice โ real recordings that download with each book and play offline, not a robotic device voice. Listening Mode plays hands-free with full controls on your lock screen and Control Center โ skip, pause, and play from your headphones like a podcast. โโ REMEMBER โโ Every vocabulary word you tap is saved to your study notebook โ the word, its reading, and its meaning. The notebook shows just the words due for review: clear one you already knew and it spaces out over days; reveal one you'd forgotten and it comes back soon โ until it's simply known. โโ YOUR LIBRARY โโ A complete original novel โ 25 chapters across five free parts โ plus two companion editions of the same story: a plain Japanese edition with no study aids, and a full English translation. Read the study edition first, graduate to the plain Japanese, or check the English when you must. Each book downloads with a single tap and works fully offline. Your reading position, settings, and notebook sync across your devices through your own iCloud. โโ PRIVATE BY DESIGN โโ No ads, no accounts, no tracking, no analytics. Nothing leaves your device except the books you choose to download. Part of the NihonGO family, alongside NihonGO Dominos (the vocabulary game) and NihonGO Manabi (the textbook course) โ three apps, one shared, frequency-built card library, so what you learn in one is what you meet in the others.
