“Minds are like parachutes, they function only when open.” – Unknown
Now that you know how to do all the sounds, it’s time to associate those sounds with the various kana (you probably already did this just a little bit from the last chapter… but it’s okay if you haven’t).
You really need to learn hiragana (at minimum) to start learning Japanese, and that’s exactly what you’re going to do here. If you don’t know hiragana you really don’t know how the Japanese language works and how it is set up. By learning hiragana a lot opens up to you and it allows you to start learning kanji as well (also important). Really, though, if you don’t know hiragana it’ll be hard to function, so I think it’s important to get that out of the way as early as possible.
In this chapter, focus on learning the kana. Learn how to read (most important) hiragana and write (not as important, but still good to know) hiragana. Future chapters will have hiragana as well (after Season 1 it’s only Japanese!) so learn it now. Even if you aren’t fast or fluent at reading it (understandable) make sure you can read it so that you can continue with future lessons!
