Instructions:
Download and extract the file to a directory.
Open index.html or index_BCCWJ.html in a browser.
The BCCWJ version uses the BCCWJ corpus of Contemporary Written Japanese using relative frequency (100 = 100th most frequent word).
The standard version uses InnocentCorpus, a corpus collected from ~5000 books, with absolute frequency (100 = occurs 100 times within these 5000 books).
The two versions might be merged in the future, currently separated for download size. (BCCWJ corpus is 5MB zipped, InnocentCorpus 1.7MB)
Note that you need the Anki addon AnkiConnect installed, see the readme.
