Hiragana and katakana (KANA) are just the bases for start learning japanese. But you're not going to be able to communicate with it propertly (or even read), so after that you need to learn KANJI. If you want to learn, you can download some APP for your movile phone: -KANA MIND -TENGU GO KANA -DR.MOKU -OBENKYO I learned with TENGU GO KANA, but there're all OK.

It's hard to answer this without know what you are having trouble with. I would learn new 5 kana every 3 days, and everyday I would write all of the kana I've learned together so I don't forget any of them. After you've reviewed the same material again and again with spaced repetition, you don't forget it. There are a lot of apps and websites that do this for you too.

I found these videos on YouTube. https://www.youtube.com/watch?v=8IpHIUxhdaI https://www.youtube.com/watch?v=kEAbfuANKWw https://www.youtube.com/watch?v=jCERk6uxIgQ https://www.youtube.com/watch?v=OLBWOOregmI I would recommend writing practice while you listen these kind of video. https://www.coscom.co.jp/hiragana-katakana/kanatable-j.html http://happylilac.net/hiragana-50.html http://happylilac.net/katakana-50.html http://happylilac.net/sy-roman.html
