After you're done with kana,
Tips for learning kanji:
Check out kanjidamage (provides good mnemonics for kanji, gives names to radicals that dictionaries such as jisho don't acknowledge at all - mnemonics here also include a way to remember the ON-yomi reading, the one you'll be using for compound kanji words without okurigana (kana following the kanji) but that only really matters if you want to do more than read. Kanjidamage also excludes ~300-400 useless joyo kanji that, according to its author, are not used anywhere anymore) and memrise (a good trainer website that not only helps you memorize like normal but also has a good pattern for refreshing that knowledge - first it lets you "water" it (plants = knowledge and all) after 3 hours, then a day then more and more and if and when you fail, that will reset which is pretty convenient). Memrise also has a course based on kanjidamage's pattern so make sure you use that.
If you find the mnemonic from kanjidamage ineffective (inevitably there are some, this is kanji we're talking about) and memrise's userbase fails to provide a better one, do your best to come up with your own. Take some time thinking it through, whatever works for your mind is good enough. You want to avoid relying solely on visual memory as much as possible. Trust me, I learnt over 3 grades of kanji (~500) before realizing how much trouble I have remembering many of them and need mnemonics.
