I have spent untold hours researching this dictionary from various sources so you don't have to. This includes original research from the 2000-year-old Setumon Kaiji. (Requiring me to learn Classical Chinese!)
When I first started learning Japanese, I yearned for a tool such as this one to help me learn kanji. Finding none, I figured that if I made it, other people could benefit. If you have benefitted, please show your appreciation by donating.
