Read authentic Japanese content. Master vocabulary in context.
Yomimaru is a Japanese reading app that takes you from your first hiragana to full novels, with reading graded from absolute beginner to JLPT N1. You read something at your level, tap the words you do not know, and those words come back as review cards until they stick. The reading comes from a curated library and from the day's news rewritten for your level. You can also bring your own material, from a pasted text or a PDF to a whole manga volume. Furigana appears only over the kanji you have not learned yet, and when a sentence will not click, the built-in tutor, Tomo-Sensei, explains it at your level.
Everything you need to master native Japanese reading.
Ditch the rote flashcard grinding and start reading real materials with integrated learning widgets.

Why Yomimaru is Different
Flashcards build vocabulary in isolation. Graded readers keep the training wheels on. Neither gets you reading the books you actually want to read.
| Feature | Yomimaru | Anki Flashcards | Graded Readers |
|---|---|---|---|
| In-Context Immersion | ✅ Read authentic light novels & articles instantly | ❌ Isolated sentence cards with zero context | ⚠️ Good for beginners' controlled practice, not for real novels |
| Adaptive Furigana | ✅ Hide known readings based on your JLPT level | ❌ Static cards; no real-time reading filter | ❌ Fixed furigana; either all-or-nothing |
| Sentence Breakdowns | ✅ Tomo-Sensei breaks down complex clauses as you read | ❌ No grammar feedback; requires external lookup | ❌ Static text without explanations |
| Content Studio | ✅ Generate custom stories, news, and dialogues at your exact JLPT level. | ❌ Only allows manually curated deck updates | ❌ Closed catalog; no custom file reading |

Frequently Asked Questions
What is Yomimaru and how does it help you learn Japanese?
Yomimaru is a Japanese reading app for learners from absolute beginner to JLPT N1. You read stories and news at your level, tap any word for its reading and meaning, and every word you look up comes back as a review card until it sticks. Furigana appears only over the kanji you have not learned yet, and the built-in tutor, Tomo-Sensei, breaks down any sentence that will not click. If you are starting from zero, a free kana course takes you to your first real story.
Can I import my own novels, files or manga to read?
Yes. Paste a text or drop in a PDF, EPUB or DOCX and it opens in the same reader, with the same lookups and furigana. Manga and visual novels go in as images or a multi-page PDF, and Yomimaru reads the Japanese off the artwork so you can tap the words in each speech bubble. Standard imports are capped at 10 on the free Ronin plan and unlimited on Samurai and Shogun. Manga pages use AI credits.
How does Tomo-Sensei assist with Japanese grammar?
Tomo-Sensei is our built-in AI tutor. It analyzes complex native sentences to break down their grammatical components, explain particles like wa and ga, isolate relative clauses, and host conversational, sentence-specific question and answer threads directly within your reading view.

Yomimaru has three tiers: Ronin (free, with 10 lifetime custom uploads, 80 signup credits and 5 credits a month), Samurai ($9.99/mo or $7.99/mo billed annually, with unlimited uploads, 500 monthly credits and spaced repetition review), and Shogun ($19.99/mo or $15.99/mo billed annually, with everything in Samurai, 2,000 monthly credits and a 14-day free trial).
