This is the Ajatt-Tools Resources List. With the help of our community we've gathered the links to help you in your Japanese studies. We prioritize libre software and content that you can download for free. Everyone is welcome to suggest more resources in our chat.

The third party resources below may contain what Tatsumoto considers to be ineffective language learning advice. If you find something that contradicts what's written in this guide, assume it's wrong or verify by asking people in our chat.






Grammar in Japanese


Examples and pronunciations

Sometimes you might find yourself in a situation where you want to add a word to your SRS but the example sentence you've found the word in is too complicated, or you've lost it because you forgot to save it. In such cases sites with example sentences come to rescue.

  • Massif. Allows you to search over 30 million unique Japanese sentences.
  • Sentence Search. Contains voiced sentences from various premade decks. Grab an offline version here.
  • Aozorasearch. Performs a full-text search on Aozora Bunko (digital library).
  • Weblio英語例文検索. Made for Japanese people learning English but can be used in reverse.
  • Forvo. Has many words pronounced in isolation but not so many sentences.
  • YouGlish for Japanese
  • 用例.jp
  • Reverso
  • I don't recommend Jisho because it suggests sentences from Tatoeba. Many of them come from non-native speakers.

Immersion material

Don't use streaming sites and sites for reading manga online if possible. Always download what you consume. Storing immersion material locally makes mining substantially easier.

Torrent trackers

A torrent tracker is a site that hosts user-uploaded torrent files. To download something (like an anime) using torrents you usually download a torrent file and open it with a torrent client. The torrent client then downloads the actual content. Before using the torrent sites, choose a torrent client.

  • Nyaa. A torrent site with anime, manga, light novels and Japanese dramas. Contains 98% of what you need to actually learn Japanese.

    Unfortunately, Nyaa is blocked in some countries. Accessing it through Tor can be difficult due to DDOS protection. If you can't access the site, use a mirror. Currently, there's only one working mirror I know, Nyaa ISS.

  • Tokyo Toshokan. A BitTorrent library for Japanese media.

  • Rutracker. Another torrent site. Has lots of Japanese movies, dramas and anime. Ongoing anime gets uploaded with a noticeable delay. Refer to Nyaa first if you watch ongoings.

    This site can be accessed through Tor.

  • Animebytes. A private tracker. Offers content similar to what you find on Nyaa ISS.

  • AvistaZ. A private tracker for Asian movies and TV-shows.

  • AsianCinema.Me. Asian private tracker for Movies only.

  • JPTVTS.US. A private tracker for japanese content only.

  • JPTV.CLUB. Another private tracker. You can join if you have accounts on other private trackers. Here you can find Japanese TV programs. Most uploads contain Japanese subs straight from the broadcast. They are extremely good for mining.

  • anisource. An aggregate site for high quality raws from Raws-4U, スカー Raws and Leopard-Raws.


  • Animelon. Watch anime with Japanese subtitles.
  • Anjsub. A site similar to Animelon.
  • B9GOOD. Watch raw anime online.
  • Another anime streaming site. You can switch between audio and subtitle tracks in multiple languages.
  • AQStream. Watch Japanese TV.
  • BiliBili. A Chinese website with a bunch of TV shows.
  • jp.m3u. A m3u playlist with Japanese IPTV channels which you can open in mpv. You can switch channels in mpv by pressing < and >.
  • Lets you watch a live stream with news, but you have to allow to run an obscene amount of nonfree JavaScript code. To avoid running nonfree JS, watch the stream in mpv by creating a desktop shortcut.
  • keylabo. Similarly to News24, lists a number of channels you can watch online. Unfortunately, not all of them can be opened in mpv.

YouTube with subtitles

Main article: Immersion with YouTube

Channels for pre-beginner Japanese learners.

Regular channels.

Important: install Privacy Redirect or LibRedirect to safely watch YouTube videos via Invidious.


Here you can watch videos from TikTok:

Find Japanese videos by tags, for example: tiktokでニュース

Browsing will lead you to more tags.



  • Torrent sites. Expore them first.

  • nhentai. For a bit of light reading. Many mangas on the site are just 25-30 pages long, which is perfect for beginners who can't bear long reading sessions yet.

    Translations are also available. Make sure to only search in Japanese.

  • Bilingualmanga. Bilingual manga reader where you can switch from English to Japanese with furigana.

  • Raw Senmanga. View raw manga online.

    • Make sure you disable JavaScript before opening the site.
    • Don't click on any Discord links.
  • Manga-zip. Manga archive.

  • Rawdevart. Raw manga online.

  • 同人あんてな. Free eromanga and doujinshi.

  • raw-cans. This website has scans of a lot of manga, as well as shounen jump, young jump and other manga magazines.

  • Itazuraneko 漫画.

  • shinmoemanga.

  • Manga Raw. Read manga online.

  • MIKARAW. Read manga online.

    • The site does not work with JavaScript disabled.

  • となりのヤングジャンプ. A site where you can read manga online.

  • DLRAW. Raw manga archived as zip and rar files.

  • RAWKUMA. Like Senmanga, hosts manga online.

    • The site does not work with JavaScript disabled.
    • Don't click on any Discord links.




Visual Novels and Games

There's a list of visual novels on Arch Wiki. Beware that most games that exist today are proprietary. Proprietary software should not exist and should not be used if you want to have freedom.

Japanese boards

You may need a Japanese IP address for some of these.

Japanese subtitles




  • LibreWolf. A web browser based on Firefox that comes with an Ad Block by default. You can find it in AUR.
  • Anki A free/libre flashcard application.
  • Sxiv. An image viewer perfect for reading manga.
  • sxiv-manga-reader. Simple manga reader made from a patched nsxiv. It extracts archives for you and opens them automatically with sxiv. It keeps your progress.
  • Trackma. Track your immersion on one of the supported sites.

Work with subtitles

  • subs2srs. Takes video files and subtitle files and creates cards with screenshots and/or audio for each line in the sub file. Useful for batch extracting audio from videos.
  • subtitleedit. A subtitle editor. It can convert image-based subtitles (.sup, .sub) to text-based (.srt) via an OCR engine such as Tesseract.

OCR for manga

Main article: Mining from manga.

  • mokuro. Can be used to OCR Japanese text instead of Tesseract.
  • Poricom. Manga OCR desktop application.
  • kanjitomo. An OCR program written in Java. Note that you can't use Japanese to Japanese dictionaries with it.

Reading eBooks

  • Cool Reader. E-book viewer.

    After installation open Settings and choose Japanese fonts to avoid Chinese fallbacks. Yu Mincho worked for me. Japanese Noto fonts did not, some text was still in Chinese.

    To add a bookmark, select some text and press Ctrl+B. To view saved bookmarks, press F6.

    Unfortunately, Cool Reader can't automatically copy selected text to the clipboard like Foliate does.

  • Foliate. A simple and modern eBook viewer. Arch Linux package.

    If you can't open books, run the chmod command from their issue tracker. In Preferences, set "When a word is selected" to "Copy" and "When multiple words are selected" to "Copy". This should be enough to comfortably use Foliate with Yomicah Search. Change Layout to "Scrolled" in Advanced section of the menu to prevent lags and ensure a consistent layout.

    Use keyboard shortcuts, "n" to go to the next page and "p" to go to the previous page. To scroll without the mouse, press "j" and "k".

  • KOreader. A book reader. The interface sucks because it was designed to be used on some obscure devices, but at least you can open a light novel and see furigana rendered properly. I recommend installing the appimage AUR package because the *-bin AUR package didn't work for me.

  • Zathura. A minimalistic document viewer. Can be used to read novels. Doesn't display furigana correctly.



  • Noto Fonts. Google Noto TTF fonts.
  • Source Han. The Adobe-branded Source Han Sans, Source Han Serif and Source Han Code JP typefaces.
  • ipa-fonts
  • Kanji stroke order font
  • 新正楷書CBSK1. A good brush font. Supports around 13,000 characters.
  • Asebi Mincho. A font that displays all 新字体 kanji in their 旧字体(正字体) form, including all the undocumented changes as well.
  • 花園明朝. This font is made by the glyphwiki project and support all unicode characters. Really good back up font when everything fails.
  • AJT archive. The fonts I use. Contains Yu Mincho, semi-cursive fonts and stroke order fonts. You can simply extract the entire folder to ~/.local/share/fonts to install them.


mpv is the best video player for language learning.

Make Anki cards in mpv:


With mpd you can listen to condensed audio, audiobooks and Japanese music.

Torrent clients

  • qBittorrent. A free/libre torrent client alternative to µTorrent. Use search plugins, they save you so much time that you'd otherwise spend going to each torrent site individually.
  • KTorrent. A BitTorrent client for KDE.
  • Transmission. A light-weight and cross-platform BitTorrent client. See transmission-gtk.


  • yt-dlp. A command-line program that lets you download videos and audio from YouTube and more than a thousand other sites.

  • mangadesk. Download manga directly from your terminal.

  • HakuNeko. A cross-platform downloader for manga and anime from various websites.

Tools for extracting audio

Note: Please read our recommendations regarding using an Android device.


  • Mozc for Android. A Japanese Input Method Editor (IME) for typing Japanese text on a phone.
  • AnkiDroid. A free/libre flashcard application, Android version.

  • Jidoujisho. A mobile video player tailored for Japanese language learners.

Audio players

Audio players are used to play locally stored audio files. Although their primary purpose is to play music, for language learning a better choice would be to listen to audiobooks, podcasts or audio extracted from movies and TV shows.

All available players are listed on F-Droid catalog.



Yomichan is a browser extension that lets you easily look up unknown words.





The quality of machine translation is very low. Your goal is not to translate Japanese but to be able to understand it the first time. Don't use translators for anything serious. You've been warned.

Language guides


How to learn Japanese on your own, having fun and to fluency.

Notable articles:


  • Includes links to the Amazon website. Amazon is known for spying on and politically suppressing its users.
  • Contains outdated information.
  • Talks about MCD, which is a flashcard format that hasn't received much adoption over the years due to being too difficult and complicated.
  • Advertises unnecessary paid products.
  • Tries to harvest Email addresses.


This site was initially introduced as a free guide designed to be applicable to any language. Later proved to be a Patreon scam, but there are some helpful articles you can read without paying money.

Notable articles:


  • The site doesn't work (the menu breaks) unless you enable JavaScript. The JavaScript code is proprietary and is not safe to run.
  • Recommends and includes links to proprietary spyware such as Hellotalk, Tandem, Bilingua, Netflix, Migaku, etc.
  • Includes instructions on how to join their Discord server. Discord is known for spying on and politically suppressing its users.
  • Collects Email addresses which is to say the least suspicious.
  • Tries to sell you useless junk.


A collection of guides for those interested in learning Japanese.


  • Includes links to non-free software.
  • Includes links to Discord servers. Discord is known for spying on and politically suppressing its users.
  • Contains outdated information.


A site on how to learn English. Made by Poles who learned English to native-level fluency. What they used to learn English can be applied for learning any other language, including Japanese.

Notable articles:

TheMoeWay and AnimeCards

Unfortunately, these two sites are clearly made with Windows users in mind, but maybe you'll find useful language learning advice there.


  • The sites try to deny the importance of freedom and legitimize proprietary software.
  • They include instructions for playing visual novels. Most visual novels should be avoided since they are proprietary.
  • They mention software that requires proprietary operating systems to run.
  • They include links to Discord servers. Discord is known for spying on and politically suppressing its users.
  • Both sites recommend "anime cards". In my opinion, TSC is the most efficient way to combine Anki with immersion.
