Find a kanji by its radicals
Click every part you recognise. The list below keeps only the characters that contain all of them, sorted by stroke count. You can do the same from the search box with the 部 button, or by typing parts like water+mouth with the input method on. Read the search guide.
Pick the parts you can see in a character. Each one you add narrows the list, and parts that no remaining character has are greyed out.
