Learn Katakana-A I U E O

First up are the core vowel characters. These are important to learn as they make up the foundation of the other characters going forward.

This is a simple lesson. Unfortunately, katakana has a few curve balls it will throw at you later.


  • → a (like “ah”)
  • → i (like “E”)
  • → u (like “ooh”)
  • → e (like “A”)
  • → o (like “oh”)


アイウエオ are the core vowel sounds in the Japanese language. They form the katakana syllabary when combined with the K, S, T, N, H, M, Y, R, W consonants.

Just like in the hiragana course, we’ll go through each set individually — and weave them all together over each lesson.
