こ vs に — HOW TO TELL THEM APART

These two Hiragana lookalikes are the most commonly confused characters by Japanese learners. Here is how to distinguish them instantly.

CHARACTER #1

こ

/ko/

Strokes: 2

“Two parallel lines, like two playful koi fish.”

CHARACTER #2

に

/ni/

Strokes: 3

“Needle and two threads on the right.”

Key Anatomical Differences

こ (ko) consists solely of two horizontal bars (top and bottom curved).
に (ni) has a vertical stem stroke on the left, plus the two bars of こ on the right.

GOLDEN MEMORY TRICK:

Remember: 'NI is a Needle (left line) next to a KO (right bars).'
