I just thought I’d share this.

I’ve always been curious about kanji frequency usage given various data sets (netflix, google, twitter), so decided to build this visualization. Just sharing in case other people might find it interesting.

You can try it out here

Make sure you sort by wanikani level

I graphed the cumulative usage of kanji across various public datasets (twitter, netflix, wikipedia) and it turns out that 80 to 90 percent of the kanji you see in the wild is made up of the first 1000 most common kanji..
