A Japanese app built entirely around immersion reading. The best way to learn to read Japanese isn’t by hours of flashcards or grammar textbooks — it’s by actually reading Japanese. Because reading doesn’t just teach you how to read — it teaches you how to describe, reason, and think in Japanese too. Reading doesn’t just teach you kanji — it builds fluency. And true fluency comes from immersion: real context, real sentences, real Japanese. That’s why we built Yomoyo, so you can have your reading content, dictionary, and study tools for immersion all in one place. 読もうよ! -- KEY FEATURES -- • Real Japanese Content Read authentic Japanese from real sources — including folktales, Japanese news articles, Wikipedia, and original stories written by Japanese authors. • Scan Physical Books Snap a photo of any Japanese book. Yomoyo pulls out the text so you can read it with furigana, dictionary lookups, and more. • AI-Powered Reading Generator Type in a topic — anime, travel, cooking, whatever you want — and instantly get a Japanese story for your reading level and interests. • Pop-up Dictionary + Kanji Breakdown Tap any word to instantly see its definition, reading, pitch accent, and a breakdown of each kanji character. No need to switch apps or guess — it’s all right there. • Vocabulary Lists + Flashcards Every word you tap can be saved to a vocabulary list and studied later with flashcards. • Export to Anki Prefer Anki or other SRS software? Export any vocab list as .tsv files to keep your flashcard system in sync. • Favorites & Recents Save your favorite stories and access them anytime — even offline. Your recently read stories are also stored automatically so you can pick up where you left off. • Furigana Toggle Show or hide furigana to control how much help you want. -- CONTACT -- Have questions or need support?
