It’s easy to use. Click ‘Kanji’ and choose which kanji words you’d like to practice.
Next, click ‘Practice’. As you are presented with each word, type its rōmaji equivalent (e.g., ‘genki’).
As you type, hiragana characters will appear. Hit ‘Enter’ to submit your guess.
If you get stuck, move your mouse over the word, and the answer will appear.
