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.







  • JLPT Grammar List. Covers grammar for all JLPT levels.
  • 問題検索室. Search JLPT questions by keyword.
  • JTest4You. Practice tests and resources by JLPT levels.
  • JLPT文法解説まとめ. Introduces you to grammar patterns that exist in JLPT. This site is much better than the rest and probably the best free way to learn grammar used in the JLPT exam.

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.
  • 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 suggest 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

  • 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, and because there's no Tor address, and they block all Tor access, we have to use mirrors. Currently there's only one working mirror I know, Nyaa ISS.

  • 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.

  • JPTV.CLUB. Another private tracker. You can join if you have accounts on other private trackers.

  • 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.

  • Japanese Youtube channels with japanese subtitles
  • 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.





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

  • subs2cia

Tools for extracting audio


I urge everyone to reject mobile phones because they're surveillance tools. If you do own a cellphone, be sure to install F-Droid, which is an application catalog for libre programs. Get rid of Google Play by flashing a new ROM or by rooting your phone and deleting all Google applications. Don't buy iThings, you can't run a free OS on them.

  • 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.

  • Tachiyomi. Free/libre manga reader for Android.



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





The quality of machine translation is very low. Don't use it 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.

Notable articles:


  • The site doesn't work (the menu breaks) unless you enable JavaScript.
  • 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.

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.
