Kana that look alike — and how to stop confusing them

Most kana reading errors come from a short list of look-alike pairs. Drill these specifically and accuracy jumps far more than another pass over the full chart would give you.

Hiragana

• ぬ / め — ぬ closes in a loop; め does not.
• れ / ね / わ — same left side; the right side differs: れ flicks out, ね loops, わ curves in without closing.
• る / ろ — る ends in a loop, ろ ends open.
• さ / ち — mirror images. さ opens to the left, ち to the right.
• は / ほ — ほ has an extra horizontal stroke.

Katakana

• シ / ツ — the classic. シ has its dashes on the left and sweeps up; ツ has them on top and sweeps down.
• ソ / ン — same principle: ン sweeps up from the bottom left, ソ comes down from the top right.
• ク / タ / ワ — ク is two strokes, タ adds a third, ワ has a squarer shoulder.
• コ / ユ — both are two strokes; ユ‘s second stroke extends past the corner.

Why stroke order is the fix

Every pair above separates cleanly by stroke direction. If you learn each character by its strokes rather than as a picture, the ambiguity mostly disappears — your hand knows which one it is even when your eye is unsure. This is the practical argument for stroke order, and it is worth more than the aesthetic one.

シ and ツ are the clearest case. As pictures they are nearly the same three marks. As movements they are not remotely alike: シ is written bottom-left to top-right, ツ top-left to bottom-left. Watch the animation on either character’s page once and the pair stops being a coin flip.

Drill them in pairs

Practising ぬ and め ten minutes apart teaches you very little. Practising them side by side, alternating, teaches you the contrast — which is the thing you are actually missing.
