Here at Japanese SE, we see many questions along the lines of "Do you know any books/programs/websites that would help me learn XYZ in Japanese?", even though we (and the stack exchange network in general), are specifically not set up to handle those questions well. Inspired by Chinese Language and Usage's method for handling resource information, we decided to try it here. The idea is to provide a go-to list for those interested in resources while the discussion about whether to allow resource questions is ongoing.

Please do not create resource questions on the main site asking for websites, books, courses, word-lists, or other "shopping recommendations", the question will be downvoted, closed and possibly deleted. Resource related questions are off-topic for Japanese SE.

If you are looking for a particular resource that you do not see on this list, the appropriate place to ask is almost certainly the Japanese SE Chatroom.

Feel free to ask in the chatroom if you have a resource you would like to add to the list, or if you have other questions. The small group that maintains this list overlaps quite a bit with those you will likely find in there.


  • Each answer covers a particular category.
  • Include a short summary with each link, describing how it is useful or who it is useful to
  • Keep your entries as succinct as possible to maintain a easy-to-follow list format.
  • Don't include links to any illegal/copyright violating content, or sites that host such content.
  • If you are a developer/provider of the resource you are adding, follow our community rules on self-promotion by including text similar to "developed/maintained by your user account link" to the resource description.
  • Comments here will be fairly aggressively moderated to preserve the presentation of the list. If you have a larger comment or complaint, either talk to a moderator in the chatroom or open a meta question.

Unless otherwise listed, assume these textbooks include or offer CDs for listening practice.

  • Genki - Arguably the most used Japanese textbook for classrooms. Textbooks have matching audio CDs with native speakers reading the vocabulary, dialogues, and some of the activities. There are also matching workbooks that focus mainly on practicing new grammar concepts from the chapters, but there are also listening pages and writing practice pages. Volumes 1 and 2 are for beginners; there is also an intermediate level text.
  • Minna no Nihongo (3a Corporation) - The MnN series focuses on daily life conversations, avoiding overly focusing on both exchange students and business Japanese. The main text is translated into several languages, and there is a blizzard of supplementary texts available. At times, MnN can have a 'workbook' feel, and it lacks some features one might expect of a beginner text (like a dictionary of words in the text).
  • Japanese From Zero - A complete course from YesJapan with good content and examples
  • Japanese for Everyone (Gakken) - A short all-in-one course suitable for either a short course in Japanese or self study. Somewhat oriented towards a business traveler.
  • Japanese: The Spoken Language - Often controversial for its use of non-Hepburn romaji, and for its kanji coverage being left entirely to the pseudo-companion textbook Reading Japanese by the same author. (Observe the review histogram at Amazon for these books and for Reading Japanese.) The positive points are an unusually deep coverage of major grammatical points and a strong focus on, as the title says, the spoken language (including extensive explanations of pitch accent). All three books in the series cover everything at least up to the JLPT N2 level (except kanji), and there are separate supplementary texts reproducing the books entirely in Japanese; as well as a companion CD (for book 1)/DVD (covering books 2 and 3).
  • Situational Functional Japanese (Tsukuba) - Classroom oriented.
  • Tobira - Intermediate textbook
  • Japanese for Busy People 1, 2 and 3 - A concise course for 'busy' students who want to learn natural spoken Japanese as effectively as possible in a limited amount of time. Volume 1 is available in Kana and Romanized versions.
  • Japanese the Manga Way - A more 'fun' approach to Japanese. Covers beginning to intermediate Japanese, with kana/kanji/romaji throughout. Unlike most textbooks, JTMW introduces both polite and plain form right from the beginning and focuses more on the spoken language.
  • Bonjinsha's Basic Kanji 1 and 2, and Intermediate Kanji 1 and 2 - This series focuses exclusively on the kanji use and different methods of mentally organizing the kanji. Note that the intermediate books are written almost entirely in Japanese, and expect some familiarity with the language. (No Audio)


(Not including dictionaries, textbooks or the books in JLPT prep materials)

  • A Dictionary of Basic/Intermediate/Advanced Japanese Grammar - Very good coverage, does a good job filling in gaps left by most of the popular textbooks/classes.
  • A Handbook of Japanese Grammar Patterns for Teachers and Learners - It contains all grammars explained in Basic/Intermediate/Advanced plus other grammars. Due to the compactness, the small enough font forces me to use a magnifying glass.
  • A Dictionary of Japanese Particles - The title is self-explanatory. Goes in depth and provides examples for over 100 particles. Particularly useful for explaining different meanings/usages of the same particle.
  • Kanji Look and Learn - An alternative to Remembering the Kanji, this book focuses more on illustrations with short mnemonics to help remember kanji instead of written stories. From the same people who made the Genki textbooks.
  • Remembering the Kana - From the author of Remembering the Kanji, this book has mnemonic devices that it claims allow you to learn hiragana and katakana in three hours each. (free sample chapter)
  • Remembering the Kanji - Always controversial. Presents a "story memorization"+"single keyword" technique to memorizing kanji meaning and writing/recognition, while ignoring readings/compounds. A free sample is available for the first ~250 characters. Volumes two and three add coverage for some pronunciation and "beyond Jouyou" characters, but are less popular than volume I.
  • The Structure of the Japanese Language - Susumu Kuno presents very deep explanations of very tricky common issues (particularly particle confusion) facing mid-level Japanese learners (N2-N3) and above. This is a linguistics book, so non-linguists may need to consult wikipedia for some vocabulary.
  • Words In Context: A Japanese Perspective on Language and Culture - Takao Suzuki investigates the differences between languages based on sociological and psychological differences of people from different cultures and gives sociolinguistic insights on why the Japanese language behaves a certain way. Investigates the logic behind uses of personal pronouns in the Japanese language.
  • 2001.Kanji.Odyssey - Kanji learning books/e-books, with audio and some online material (some available free). Contextual (i.e. with compounds/sentences) method.


(Books to improve Japanese reading skills)

  • New Penguin Parallel text: Short stories in Japanese - Eight stories of varying length and difficulty, all by well known writers all born after WW2. Edited by Michael Emmerich
  • Rapid Reading Japanese - Will re-introduce basic skills you already use unconsciously in your native language in enjoyable exercises. Second edition was recently published with significant revisions to bring it up to date.



Add-ons (browser)


  • Rikaikun - When activated, just put your mouse over a Japanese word to see its phoenetic reading and a translation to English. Based on the rikaichan add-on for Firefox.
  • Yomichan - "This extension was inspired in part by Rikaichan and Rikaikun, but it stands apart in its goal of being a all-encompassing learning tool as opposed to a mere browser-based dictionary, while adding advanced features such as EPWING support." It also features automatic flashcard creation for Anki.


  • Itadaki is a browser addon that simplifies adding furigana (ruby tags).
  • Perapera Japanese - Put your mouse over any Japanese words on a webpage and it gives you the pronunciation and definition. Alternative to Rikaichan.
  • Rikaichan - When activated, just put your mouse over a Japanese word to see its phoenetic reading and a translation to English (or German or French or Russian).
  • Yomichan - Yomichan is available on Firefox too.


  • Rikaikun - When activated, just put your mouse over a Japanese word to see its phoenetic reading and a translation to English. Based on the rikaikun add-on for Chrome. If you're running legacy Presto based Opera (up to version 12), you want Rikaisan.


  • Safarikai - When activated, mouse over a Japanese word to see its reading in kana and translation to English.

Tablet & Mobile Apps

Note that several of the dictionaries are also available on these platforms. Many of the programs listed in software also have iOS or Android variants.


  • Aedict - Japanese <-> English EDICT-based dictionary with example sentences. A paid version, Aedict3 adds functionality and upgrades the interface.
  • Google Japanese Input - Based on Google's IME for computers. A little more intuitive than Simeji, but still in beta so it might have more bugs too. Allows traditional 12-key tap, flick, tap+flick together, and QWERTY touchscreen input as well as hardware QWERTY input. Kaomoji is easier to access and better organized than Simeji's.
  • Go Keyboard - along with the Japanese for GO Keyboard add-on, provides a Japanese input with flick, toggle and QWERTY support.
  • JED - Japanese <-> English EDICT-based dictionary similar to Aedict.
  • Obenkyo - Practice writing kana/kanji with proper stroke order or just do flashcard tests of kana, kanji, words, and particles. Also has a section for reading numbers in either kanji, hiragana, or romaji.
  • Simeji - Japanese input method. Allows traditional 12-key tap, flick, bell, and QWERTY touchscreen input as well as hardware QWERTY input. If you have Android 1.5 or earlier, then you need to use Simeji Classic.
  • A variety of other EDICT-based dictionaries are available: Midori, Makimono and Kabuto are three examples.


  • KanjiBox - iPhone/iPod/iPad app offering drill-type exercises and flashcards (both using SRS) for kana, kanji, vocabulary and reading. Extra modules use touchscreen to drill on kanji/kana drawing. Gives out detailed stats and global scores. Links with online version. Created by one of our users.

  • Imiwa? - Free J<->E dictionary app, with example sentences, kanji stroke orders, conjugations and several kanji lookup methods. Uses the free EDICT dictionary and the Tanaka/Tatoeba corpuses. (This app replaces Kotoba! on the iTunes Store)

  • ジーニアス和英・英和辞典 - The official app for the dictionaries. Included in many 電子辞書, this pair of dictionaries include example sentences and images, and are among the lowest-cost commercial dictionaries. Note that the dictionaries and app are aimed towards Japanese-speakers learning English, but are also suitable for intermediate-advanced students of Japanese.

  • JSensei a series of lessons, gradually increasing in difficulty. Seems to be using the dictionaries/word-lists from smartfm (see the websites section)

  • Midori - EDICT dictionary app

  • Nihongo - Japanese-English dictionary and study tool. Includes example sentences, commonality rankings for words, SRS-based flashcards, and the ability to create flashcards from any piece of Japanese text.


  • JiShop Kanji Dictionary - Features a simplified "by-radical" lookup that works extremely well and quickly. Dictionary is not "yet another kanjidic skin". Also available for iOS, Android and WindowsMobile.

  • Bunpo - Covers the grammar from N5(easy) to N1(hard). (Assumes knowledge of kana and some kanji)


Unreliable sites, apps, and tools that you should stay away from:

  • JLPT Sensei/JLPT先生 - A commercially motivated site fraught with mistakes, non-idiomatic and ungrammatical sentences. For some examples, see this comment and this comment. Making it more harmful to Japanese learning is the fact that it constantly ranks among Google's top search results, and as a result a lot of learners have used the site. It should be avoided like the plague.

  • Avoid machine translators such as Google Translate, DeepL, and RomajiDesu when attempting to comprehend or create natural sentences. Although they have made great progress as a technology, they are incredibly poor at understanding context and word usage. They should never be used as a dictionary or as an example of natural Japanese.

The creation of this section has been inspired by a discussion under this question where the need to advise learners, especially elementary and intermediate level learners, against certain misleading or erroneous sources was made clear.

  • Is it worth it to mention that online machine translation tools are often worse-than-useless in many cases? Commented Jan 28, 2021 at 23:31
  • @EiríkrÚtlendi I agree. Would you care to add them? I've only had experience with Google Translate. I think some other Japanese-English machine translation tools have been (usually negatively) commented upon on the site, but I can't remember any of them.
    – Eddie Kal
    Commented Jan 29, 2021 at 0:31
  • I would say the DeepL is excellent at translating Japanese into English, and that it does a reasonably good job from English to Japanese. I think you're being a little harsh on them since they can be used to good effect as tools to expand vocabulary (for example) rather than tools to simulate native language patterns.

Pronunciation and pitch accent

Online resources

  • Sanseidō Daijirin, 3rd edition - A monolingual dictionary that also lists pitch accent. Designed for native speakers. Lists pitch accent for a very large number of words. Uses numeric notation, with [0] for no accent, 1 for accent on the first mora, and so on. (Expired.)
  • OJAD (Online Japanese Accent Dictionary) - Designed for learners to use. Includes audio. Lists 9000 nouns and 3500 inflecting words (verbs and adjectives). Particularly useful for the latter, as it shows how the pitch accent changes with inflections. Includes Prosody Tutor Suzuki-kun, a unique tool that shows pitch accent in the context of entire sentences.
  • Japanese Accent Study Website - Designed for learners. Shows how pitch accent changes with inflection. Although it's not as comprehensive as OJAD, it contains some useful information such as pitch accent for numeral-counter combinations and Japanese names, which can be hard to find elsewhere.

Other resources

  • NHK 日本語発音アクセント新辞典 - The latest edition of a pronunciation and pitch accent dictionary from the NHK (the national broadcaster). Largely revised and enlarged since the previous edition, with numerous up-to-date accentuations. iOS subscription with audio is available as a part of dictionary app suite.
  • 新明解日本語アクセント辞典 - A competing pitch accent dictionary from Sanseidō. Mostly based on native Tokyo accent and particularly detailed in conjugational and periodizational information.
  • Kenkyūsha's New Japanese-English Dictionary, 4th ed. - This was one of the few bilingual dictionaries that listed pitch accent. Unfortunately, pitch accent information was removed from the fifth edition.

    Re: Daijirin, the numbering specifically marks the location of the downstep, where pitch drops: [0] means no downstep, [1] means after the first mora, etc. I bring this up as "accent" could be misinterpreted by English speakers to be equivalent to "stress". If this is just a quibble, please ignore. :) Commented Mar 22, 2018 at 20:39

Audio pronunciation

Dedicated JLPT preparation materials

Note: Questions about the JLPT test format, times, statistics and difficulty level are explicitly OFF TOPIC on japanese.stackexchange.com and will be closed and deleted. Questions about the japanese language that is used on the test, or that involve the underlying language concepts that are tested on the test are on topic.


  • 完全マスター - A series of books that cover the grammar needed for each level
  • 日本語総まとめ - A fairly complete lesson series with different books covering each needed learning component. (Kanji, Vocabulary, Reading, etc)


  • J-CAT - An adaptive JLPT-like test site
  • JGram - A Japanese Grammar Database. Has materials for all levels of the JLPT.
  • JLPT Official Site - Includes scheduling and sample tests
  • tanos.co.uk - provides resources for the JLPT N5-N1. It includes help for, reading, listening, grammar, kanji, vocabulary, and has past papers. It even has a skill checker that can mark how far you've come/need to go to pass.
  • thbz.org - provides lists for JLPT vocabulary.
  • 日本語の森 - Nihongo no Mori - a JLPT grammar point-focused Youtube channel

(Please note that the JLPT FAQ states that there will not be a list of vocabulary, kanji and grammar items released for the new levels, so many of these are based on the previous JLPT 1-4 lists before the new JLPT N1-N5 came out.)

  • The links for 完全マスター and 日本語総まとめ are broken (they just link to the Amazon homepage now). Also, 完全マスター has a new version 新完全マスター.
