You can learn Japanese by reading, and for many adults it’s the most reliable way to get the volume of input the language demands. The short version: learn kana first, start with graded readers that have furigana over every kanji, move to simplified news and learner stories, then manga and light novels, and use a lookup tool that can find word boundaries for you, because Japanese doesn’t put spaces between words.

Japanese looks like the hardest language to read your way into. It’s also the language where reading pays off most, because the writing system is something you can only really learn by seeing it thousands of times. Here’s how to get from your first hiragana to your first novel.

Why reading works so well for Japanese

Two things make Japanese different from, say, Spanish.

First, there’s a long distance between the language and English. You can’t lean on shared vocabulary the way an English speaker can in French. Every word has to be met, recognized and met again. That takes a lot of input, and reading is the fastest input you can control: you set the pace, you can re-read, and you can look things up.

Second, the writing system rewards exposure. Kanji are much easier to remember as parts of words you keep seeing than as isolated characters on a list. Many learners find that a few hundred graded stories teach them more kanji, in context, than the same hours spent drilling a list.

The same coverage research that applies everywhere applies here. Reading is comfortable when you know about 98% of the running words on the page, and it gets hard fast below 95%. (We dig into the numbers in the 98% rule.) In Japanese, the trick is that “knowing a word” includes being able to read how it’s written. That’s where furigana comes in.

The three scripts, briefly

Written Japanese mixes three scripts in the same sentence.

  • Hiragana (46 basic characters) writes grammar: particles, verb endings, and words that have no common kanji.
  • Katakana (also 46 basic characters) writes loanwords, foreign names and emphasis: テレビ (terebi, TV), コーヒー (kōhī, coffee).
  • Kanji write most nouns and the stems of verbs and adjectives.

Learn both kana sets before anything else. It takes most people one to three weeks of short daily practice, and it unlocks almost every beginner reader.

Kanji are the long project. Japan’s official list of characters for general use, the Jōyō kanji, was revised in 2010 and now has 2,136 characters. Schoolchildren learn just over a thousand of them in elementary school, and Japanese children’s books lean heavily on furigana until they do. You don’t need all 2,136 to start reading. You need enough of the common ones, plus readings handed to you for the rest.

Furigana, and why it matters so much

Furigana are small kana printed above (or beside) kanji to show how they’re read. 漢字 with furigana shows かんじ on top.

For a learner, furigana changes everything. Without it, an unknown kanji is a wall: you can’t sound it out, you can’t easily look it up, and you can’t connect it to a word you might already know by ear. With it, the kanji becomes just another word you can read aloud, hear in your head and look up in a second. Every time you see it, the shape and the sound get linked a little more.

That’s why the best path through Japanese reading is really a path through furigana:

  1. Full furigana on every kanji (graded readers, children’s books, NHK Easy).
  2. Furigana on harder kanji only (many shonen manga, some learner material).
  3. Furigana only on rare or unusual readings (most novels, including light novels).
  4. No furigana at all (newspapers, most adult nonfiction, the web).

A good rule: don’t leave a stage until reading at it feels easy. And don’t be embarrassed to read with furigana for a long time. Native readers do too.

Graded readers: where to start

Graded readers are books written with controlled vocabulary and grammar for learners. In Japanese, the main ecosystem is built around tadoku (多読, “reading a lot”), an extensive-reading approach promoted by the nonprofit NPO Tadoku Supporters (NPO多言語多読).

The Tadoku levels

The NPO grades books on a shared scale. According to its levels page:

Level Name Vocabulary Words per book Rough JLPT match
0 Starter 350 200–400 (none given)
1 Beginner 350 400–1,500 N5
2 Upper-beginner 500 1,500–3,000 N4
3 Lower-intermediate 800 2,500–6,000 N3
4 Intermediate 1,300 5,000–15,000 N3–N2
5 Upper-intermediate 2,000 8,000–25,000 N2–N1

The JLPT column is the NPO’s own loose guide, not a promise, and the page also lists an easier Pre-Starter level below Level 0. Level 0 and 1 books stick to polite present and past forms; plain forms, て-forms and conditionals arrive at Levels 2 and 3.

Free readers

The NPO hosts a free library of graded books you can read online or download as PDFs, many with furigana and some with audio narration. Many of the free titles sit at the lower levels, which is exactly where you need the most volume. They’re shared under a non-commercial, no-derivatives license, so read and print them freely, but don’t repost edited versions.

The NPO’s graded readers page lists the main print series:

  • Japanese Graded Readers (Ask Publishing): Levels 0–4, 86 books sold in packs. Includes abridged classics by authors such as Natsume Sōseki.
  • Taishukan Japanese Readers: Levels 0–5, 55 books in packs, and the main source of Level 5 titles.
  • Nihongo Tadoku Books (NPO Tadoku Supporters): Levels 0–3, sold individually, also available as an app from White Rabbit Press.

Packs are not cheap if you buy them new, so check your library first. University libraries with Japanese programs often carry them.

Let’s Read Japanese

A separate series, Let’s Read Japanese from Oxford Brookes University, is graded to the CEFR instead of the tadoku scale: six levels of ten books each, running from A1 to B2. Its levels don’t line up one-to-one with tadoku levels, so treat each series on its own terms and start one step easier than you think you need.

If you’re wondering when to move from graded material to native content, we compare the two in graded readers vs native content.

Beyond books: news, stories and websites

NHK News Web Easy

NHK, Japan’s public broadcaster, has published simplified news for foreign residents and children for more than a decade. NHK News Web Easy rewrites selected real news stories in easier Japanese, with furigana you can turn on and off and audio you can play along with the text. Some reviewers note that the audio is synthesized rather than read by a person.

It’s a natural step after Level 2 or 3 graded readers. The topics are real, the sentences are short, and each story is often a simplified version of a regular NHK article, so you can later read the full one as a challenge.

Satori Reader

Satori Reader is a paid reading app built only for Japanese. It offers a large library of serialized stories and articles (more than 1,650 episodes at the time of writing), with native-speaker audio, inline grammar and vocabulary notes, and built-in review cards. You can choose to read in kanji, kana, or kanji with furigana.

At the time of writing, its pricing page lists a free tier with selected episodes and a Pro plan at $9/month or $89/year. Satori is one of the best options for intermediate learners who want polished, explained Japanese with matching audio. If you want only Japanese and you value the explanations, it may be the better pick over a general reading app.

Watanoc

Watanoc (和タのC) is a free web magazine in easy Japanese, with articles tagged N5, N4 and N3 about food, travel and daily life. The newest dated articles we could find are from 2016, so think of it as a back catalog rather than a living site. The archive is still useful for beginners who want short, cheerful, real-world texts.

Manga and light novels

Manga

Manga is where many learners first read something “real.” Pictures carry a lot of meaning, dialogue is short, and many series aimed at younger readers print furigana over the kanji.

Yotsuba&! (よつばと!) is the classic first manga. It follows a five-year-old girl through everyday life, so the vocabulary is concrete and the situations are obvious from the art. Most kanji carry furigana. The catch is that the dialogue is very casual, with contractions and child speech you won’t meet in textbooks. Read it after a few weeks of graded readers, not instead of them.

Shonen manga (aimed at teenage boys) often include furigana, which is why series in magazines like Weekly Shōnen Jump are popular with learners. Check a sample page before you buy; furigana practice varies by publisher and series, and seinen and josei titles for adults often drop it.

Light novels

Light novels are short, dialogue-heavy novels, often with anime or manga adaptations. They’re a good bridge to full novels because the prose is plain and the stories are easy to follow, especially if you’ve watched the adaptation. Furigana usually appears only on rare kanji or unusual readings, so you’ll need a lookup tool. They suit learners around tadoku Level 4–5 or JLPT N3–N2.

A level-by-level path to learn Japanese by reading

Here’s a plan you can follow. Move on when the current stage feels easy, not when the calendar says so.

Stage 1: kana and first stories (weeks 1–6)

  • Learn hiragana, then katakana.
  • Read tadoku Pre-Starter and Level 0 free books, which are often hiragana-only or fully annotated.
  • Re-read favorites aloud. Speed comes from repetition.

Stage 2: graded readers with full furigana (months 2–6)

  • Read Levels 1–2, as many books as you can. Aim for volume over difficulty.
  • Start learning common kanji alongside reading, but let reading do most of the work.
  • Save a handful of new words per session for review.

Stage 3: news and learner stories (months 6–12)

  • Move to Levels 3–4, NHK News Web Easy and learner apps such as Satori Reader.
  • Try turning furigana off for kanji you know, and back on when you get stuck.
  • Start an easy manga like Yotsuba&!.

Stage 4: native content with support (year 2)

  • Manga with partial furigana, light novels, articles on topics you know well.
  • A lookup tool becomes essential here, because most kanji are no longer annotated.
  • Many learners start sentence mining at this point: saving whole sentences with one new word each.

Stage 5: reading freely

  • Novels, essays, the web, no furigana.
  • Re-read early graded books occasionally. You’ll be surprised how fast they go.

Lookup tools and the problem of no spaces

Japanese is written without spaces between words. 私は本を読みました (“I read a book”) has five words and zero gaps. For a native reader the kana-kanji rhythm shows the boundaries. For a learner, especially one facing unknown kanji, it’s often unclear where one word ends and the next begins.

That’s why lookup tools for Japanese do two jobs:

  1. Segmentation. The tool has to split the text into words. Software uses dictionaries and statistical models (tools such as MeCab are common) to guess the boundaries. They’re good but not perfect, especially with names, slang and long compounds.
  2. Deinflection. Japanese verbs and adjectives change form a lot. 読みました, 読んで and 読まなかった all come from 読む. A good tool traces the form back to the dictionary word.

Popular options include browser extensions like Yomitan (free, for Chrome, Firefox and Edge), reading apps with their own parsers, and plain dictionaries like Jisho for copy-and-paste lookups. Whatever you use, the goal is the same: an unknown word should cost you a second, not a minute, so you stay inside the story.

One caution: tap-to-translate tools make it easy to read text that’s far too hard. Lookup speed helps, but it doesn’t replace coverage. If you’re tapping more than one word per line, step down a level.

Where Lumo fits

Lumo is a reading and listening app we’re building. It isn’t available yet, but it’s coming soon. It splits Japanese text into words you can tap for a meaning in context, saves new words with their sentences, and turns them into flashcards scheduled with FSRS. Every text gets a difficulty label based on how many of its words you already know, which takes the guesswork out of “is this too hard yet?” It also includes Lumo Stories, short original graded stories in Japanese at A1 to B1, for the stretch between your first graded readers and native content. You can import your own texts, web articles, YouTube videos and EPUB books too.

If you’re learning more than one language, our guide to learning Chinese by reading covers the same ideas for a script with no kana to lean on.

FAQ

Can you really learn Japanese just by reading?

Reading can carry most of your vocabulary, kanji and grammar growth, but most learners combine it with listening and some speaking practice. Reading alone won’t train your ear or your pronunciation. A good balance is reading as the core, with audio versions of what you read whenever they exist.

How many kanji do I need to start reading?

None, if you start with furigana. Graded readers and NHK News Web Easy annotate every kanji, so you can begin right after learning kana. To read native material without furigana comfortably, you’ll eventually want most of the 2,136 Jōyō kanji, but you’ll learn many of them through reading itself.

Should I turn furigana off?

Turn it off for kanji you already know, if your tool allows it, and leave it on for the rest. Forcing yourself to read without furigana too early turns reading into a kanji quiz and slows you down. The aim is to read a lot, and comfort is what keeps you reading.

Is manga good for learning Japanese?

Yes, with two caveats. Manga dialogue is casual and full of slang, contractions and character voices, so pair it with graded readers or news for more standard Japanese. And pick series with furigana until your kanji knowledge can handle text without it.

What should I read after graded readers?

NHK News Web Easy, Satori Reader and easy manga are the usual next steps, followed by light novels and books whose stories you already know. Choose texts where you know about 95% or more of the words, and use a lookup tool for the rest.
