Katakana quiz
Pick rows and a mode: read the katakana and choose its sound, type the romaji, or see the sound and write the character with your finger. Mistakes come back sooner.
The quiz needs JavaScript. The katakana chart works without it.
Pick a mode
Choose the sound for a katakana, type its romaji, or write it with your finger from the sound alone. The writing mode checks the direction of every stroke, which is exactly what tells シ from ツ and ソ from ン.
The pairs that trip people up
These katakana have a look-alike in the same script: ア and マ, イ and ト, ウ and ワ, ク and ケ, コ and ユ and シ and ツ. The quiz keeps sending back the ones you mix up.
Why katakana needs its own practice
Katakana spells loanwords, foreign names and sound effects, so it shows up on menus and signs more than in textbooks. Learners who know hiragana well often read katakana slowly for months; a few rounds a day fix that faster than reading alone. The katakana chart has every stroke order.
