"The" Japanese Core10k deck, but I modified it with the following changes:
- Manually corrected translation errors – there were many in the 6k-10k segment.
- Minimalistic card format.
- Deleted most of the unused fields.
- Changed fonts to Klee One and Noto Sans, which are both free.
- Images were removed because they weren’t good and to avoid copyright issues.
- Converted audio from mp3 to opus to fit Ankiweb's 250MB deck size limit, with no noticeable loss in sound quality.
Also, if I remember correctly, words from Genki were moved to the front (this was done by the person whose version I originally downloaded).
