Thank you dear RJ member for that explanation!
Yes, Eric-san. First of all, welcome to Rocket Japanese. We are delighted to have you join us in your journey of learning Japanese.
Writing Japanese can be challenging, but it's certainly rewarding, and with Rocket Japanese, it will be fun! :P
As our dear RJ member has guided you above, the Writing sections in the Grammar and Culture lessons contain Handwriting videos that show you step-by-step how to write Japanese script. We begin with Hiragana, then once you've mastered each one of them, move on to Katakana. By the time you've familiarized yourself with Hiragana and Katakana, you'll feel excited to jump to the Kanji characters! Don't worry, we go one-by-one, literally, from how to write the Number 1.
If you have any questions, comments... or simply want to post how you're getting along, I'd be happy to reply anytime, any day!
Enjoy! :P - SAYAKA
