Install · Benchmarks · Architecture · Extension · Sharing · Chrome Web Store guide · Privacy · Contributing
Hachidori is a blazing fast Japanese Dictionary Chrome Extension that is feature rich and optionated.
Install in 15 seconds
Click here to install from Chrome store. (note: this will always lag behind the repo and may have bugs fixed in the repo)
Every GitHub release also ships an unsigned Firefox 153+ desktop package
(*-firefox-unsigned.xpi) for temporary installation; it is not on
addons.mozilla.org yet. See the Firefox guide; media
recording is not included in that edition.
Blazing Fast
Hachidori is 83 times faster than the worlds most popular Japanese dictionary app at importing dictionaries.
See the measured results.
Media mining
Hachidori can record your screen and capture sentence audio + a gif. Not just in Chrome but in all windows on your desktop.
This feature is experimental and may not work very well. I may remove it or reduce it also.
See Media mining setup, limits, and verification.
Custom Dictionary
Do you keep on seeing a name pop up over & over again in a book, but it's not in the dictionary?
With Hachidori, you can highlight the word and add it as a custom definition.
Lookup blur
Sometimes we fall into a trap of looking up a word over & over again, but never learning it.
Hachidori records how many times you have looked up a word and can blur it for you for a few seconds to force you to remember it.
It can even use anki.
Sharing
Set up Hachidori once and use that setup from every other Hachidori, in GameSentenceMiner, another browser or another computer. Same dictionaries and settings used across multiple Hachidoris.
Install Hachidori Relay for Anki from Settings → Sharing → Download the Anki add-on, then follow the sharing guide to link your other browsers.
Experimental features
Settings → Advanced → Experimental features switches on work that is still changing and may be removed:
- Media mining — the screen and audio capture above.
- Long dictionary entries — find entries longer than the scan length (proverbs, titles) without scanning further on every hover.
- MDX dictionaries — import MDict
.mdxdictionaries with their.mddresource files from Add dictionaries, next to Yomitan ZIPs. Choose the.mdxand its.mddfiles together.
Opinionated
Hachidori is an opinionated program. If it does not benefit me, the creator, personally than I will not add that feature.
I do this because I am a pretty average learner, and if I make this tool great for myself than I am making it great for the average Japanese learner.
AI Usage
This program was created with the assistance of AI. I used GPT 5.6 Ultra, and then GPT 6.0 Astra Ultra exclusively. When Codex goes down, I use Fable 5.1 with ultrathink and ultracode.
I have reviewed all plans, I set the direction of how this program works. Large parts of the program such as the actual dictionary core are hand-written.
I also have personally been using this for months, and as I am the main user of this program I find bugs pretty often which I fix.
The assets used are AI generated. If you are an artist and want to contribute to open source, please feel free to make a real logo or a visual novel style background.
