Reading is one of the most powerful ways to build your Japanese vocabulary and fluency. But if you're at an intermediate level, picking up a novel meant for native speakers can be deeply discouraging. When you have to look up every other word, you quickly lose the plot, and the pleasure of reading turns into a joyless chore.
This is where graded readers come in. These are classic stories and modern tales that have been carefully adapted for language learners. With vocabulary and grammar controlled to match a specific CEFR level, they allow you to follow the story, enjoy the journey, and learn naturally, page by page.

Frequently asked questions
What exactly is a graded reader?
A graded reader is a book that has been simplified for language learners. The vocabulary, grammar, and sentence length are carefully controlled to fit a specific proficiency level, like B1. This allows you to read comfortably and build confidence without the frustration of tackling a book meant for native speakers.
Why should I use graded readers to learn Japanese?
Reading is a fantastic way to acquire new vocabulary and internalise grammar in a natural context. Graded readers make this process enjoyable and efficient. They provide the satisfaction of finishing a whole book, which boosts motivation and makes language learning feel less like a task and more like a hobby.
How do I know if a B1 level book is right for me?
A good guideline is the 'five-finger rule': open a random page and count the words you don't know. If there are more than five, the book is likely too difficult. Our B1 readers are carefully calibrated to ensure the language is challenging but manageable for an intermediate learner.
What makes Pentecost Publishing's graded readers different?
Our readers are designed as a complete system for self-study. Key features include a bilingual margin glossary with translations into your native language, a gradual increase in sentence length within the book, exercises for every chapter (in print and online), and printable flashcards. Our vocabulary is also selected based on scientific analysis of word frequency, so you learn the most important words first.
Should I look up every single word I don't understand?
Not necessarily. The goal of extensive reading is fluency and enjoyment. First, try to guess the meaning from the context. If a word seems important or you can't figure it out, our Pentecost editions provide an instant translation in the margin, so you can check it without breaking your reading flow or reaching for a separate dictionary.
