Type or paste kanji, hiragana, or katakana to generate a printable practice sheet. Each character gets readings, faded stroke order guides to trace, and empty boxes to fill. On paid plans the sheet options change the paper, box size, guides and how much detail is printed.
This is a 3 page sheet for 日本語 made with the sheet options of the paid plans: the first page is shown below, open the PDF to see them all.

Strokes generally start at the top left. Horizontal strokes come before the vertical strokes that cross them.
The centre lines in each box help you balance the components, keeping the character the same size every time.
Trace the faded guides first while saying the readings aloud, then fill the empty boxes from memory.
