Ready to take your Japanese reading and listening comprehension to the next level? Welcome to Satori Reader. COMPELLING STORIES Read from a growing library of engrossing stories written by native speakers for intermediate students, across genres such as fantasy, slice-of-life, thrillers, documentaries, news, and more. AUDIO Tap any sentence to hear it read aloud by native voice actors (no robots!). ADAPTIVE KANJI USAGE Crack the chicken-and-egg problem of reading kanji with our unique presentation engine, which adjusts the Japanese text to accommodate your actual knowledge. This allows you to challenge yourself for the kanji you should know without being overwhelmed by what you don't. SMART DEFINITIONS Tap any word for a definition. This is more than just an automated lookup. Satori Reader shows the actual sense of each word as it's being used in the sentence. For example, the particle の has many uses: it can indicate possession; it can turn the preceding verb or phrase into a noun; it can stand in for another word; and more. We show you exactly what is happening in every instance of every word. FRIENDLY ANNOTATIONS Gray underlines indicate longer annotations that break down tricky expressions, provide cultural background, or help you to read between the lines. Our editors work hard to anticipate what might be confusing and proactively help you to make sense of things. Good-bye, confusion. Hello, clarity! SPACED REPETITION SYSTEM (SRS) The built-in spaced repetition review system helps you to build your vocabulary. Create review cards instantly as you read. Each card you create takes along a snapshot of the sentence in which you encountered the word, further helping to cement it in your memory. You can even play back the audio of that sentence while reviewing the word! HUMAN FEEDBACK Still confused about something? Just ask in the discussion section below each episode. Our team of friendly human beings is ready to help. Satori Reader is built by a team that cares. Our goal is to bring satori (enlightenment) into your Japanese reading life.

Yukimoji teaches Japanese the way it should be taught: in order. Every kanji and vocabulary word is introduced only after you've learned the pieces it's built from, so nothing ever feels out of reach. CHOOSE YOUR PATH • Kanji-first: master all kanji — in JLPT or frequency order — before starting vocabulary • Vocab-first: learn useful words immediately; any kanji or radicals you're missing are taught automatically, right before the words that need them SMART SPACED REPETITION Yukimoji schedules reviews with FSRS, a modern spaced-repetition algorithm that shows you each item right before you'd forget it — so you spend time learning, not re-reviewing things you already know. LEARN IN CONTEXT • Five example sentences per word, each introducing exactly one new element • Audio for every word and sentence, in both female and male voices • Tap any sentence for a full word-by-word breakdown with grammar notes • Grammar points taught in the same stream, with dedicated in-depth lessons START FROM ABSOLUTE ZERO • Hiragana and katakana lessons, drills, and confusable-character practice • Clear guides that explain how the language actually works ALREADY KNOW SOME JAPANESE? Skip what you've learned elsewhere — exclude entire JLPT levels or paste in a list of kanji and words you already know, and Yukimoji will never teach them. MAKE IT YOURS • Write your own mnemonics for any kanji, radical, or word • Set your daily lesson pace • Browse the full library of kanji, radicals, vocabulary, and grammar anytime Whether you're on day one or coming back after years away, Yukimoji gives you a single ordered path from zero to fluency.
