Novel difficulty list
This is a list of novels, both light novels and traditional novels, ranked by their difficulty, on a scale from 0 to 100, where 0 is very easy and 100 is very hard. You can use it to find the most appropriate novel to read based on how good your Japanese is.
If you already have a novel in mind which is around your level you can also search for it, and then click on "Show details..." to see other novels of similar difficulty.
