Thanks! A while ago I decided to scour jisho/other dicitonaries for all its rarer/unique words so added them all to my anki. I think at this points I have hundreds if not over a thousand weird ones under different kana. I also try to research alot of the stuff I add which sometimes leads to me wasting a lot of time xD

いちご・strawberry
