If you're looking for books, I would recommend the Japanese From Zero series. You can buy them on Amazon, and I think they are really great because they teach you grammar, vocab, kana, and in later books kanji. You can also get separate books for hiragana and katakana if you want extra practise! I think there are about 5 books in the series, but the first few should give you a basic understanding of the language. And memories is a really great website to help you remember the characters, but I find that writing them out is beneficial. I hope this helped!
