About Japanese

Where Japanese is spoken

Japanese is the national language of Japan. Communities of speakers exist worldwide, especially in Brazil and the United States.

How many people speak it

Japanese has about 125 million speakers, almost all of them in Japan, with diaspora communities especially in Brazil and the United States.

Grammar and structure

Japanese is agglutinative: verbs and adjectives conjugate with suffixes for tense, politeness, and negation. The basic predicate is often SOV or topic–comment. Politeness levels (keigo) are socially important. Writing uses a mix of kanji (logographs) with hiragana and katakana syllabaries.

Frequently Asked Questions

Start by identifying your CEFR level (A1–C2). You can take our free online placement test to determine your reading level in Japanese. Then use the filters on this page to browse books at your exact level. Each of our books is calibrated so that you understand about 95% of the vocabulary, which research shows is the sweet spot for natural language acquisition. If you are unsure, start one level below your estimate — you will build confidence and move up quickly.
The most effective way to learn to read in Japanese is simply by reading — a lot, and at the right level. Linguist Stephen Krashen's research on extensive reading shows that reading for pleasure at a comprehensible level is the single most powerful method for language acquisition. Graded readers like ours are designed for exactly this: they offer engaging stories calibrated to your level, with built-in glossaries so you never need to stop and look up words. The more you read, the more vocabulary and grammar you absorb naturally.
The quickest way is our free CEFR placement test, which estimates your reading level in just a few minutes. For an official certification, consider internationally recognized exams such as JLPT, BJT (Business Japanese Proficiency Test). These tests assess reading, writing, listening, and speaking and map to CEFR levels (A1–C2) that correspond directly to our book levels, so you will always know which books suit you.
Graded readers work because they apply the principles behind the Pentecost Method. The 95% Rule ensures you encounter roughly 5 new words per 100 — the optimal rate for acquisition according to Hu & Nation's research. The Retention Loop uses strategic vocabulary recycling and end-of-chapter exercises to beat the forgetting curve. And Motivation First means you read compelling stories instead of textbook drills, which keeps your brain's Affective Filter low and makes learning effortless.
