If you want to learn japanese, you first have to study the hiragana and katakana.
Why not start with katakana ?
You will find flash cards, exercises, and even a sketchpad to start writing !
You are even going to learn a lot of vocabulary because katakana are here to write foreign words, and Japanese use tons of them !
