This site is a repository for my Japanese and kanji studies. Basically, anything interesting that makes me think "I wish I had this resource when I was first studying kanji!" will be shared here.
So, if you are a kanji nerd like me, please take a look around, and I hope you find the stuff here useful! Feel free to contact me with any corrections or suggestions.
