Memory tip

A flat illustration of a bar of metal, with the kanji 鍵 ("key") drawn into the picture.

Break 鍵 down and you get 金 (metal / gold) — metal kept under a roof — something precious. Picture a bar of metal, put 鍵 inside it, and let that scene stand for "key" — key. The odder the picture, the better it sticks.

Writing Tips

  • Follow the order strictly: top-to-bottom and left-to-right. Correct order makes the shape balanced and natural.
  • Keep each stroke in one smooth motion — don't lift the pen in the middle of a stroke.
  • Close enclosing strokes cleanly so the character does not look open or broken.
  • Common mistake: drawing strokes bottom-to-top or right-to-left. Even if the result looks similar, the wrong order shows in handwriting and makes it harder to read.
