You should give anki a try. https://apps.ankiweb.net/ It's a flash card system to learn pretty much any facts, but works really well for vocab. The cards are organized into decks and you can download lots of decks for Japanese. When you study a deck, the software will present you with some new and some review cards. Cards you don't know or find harder to recall will be shown to you again. It's free for non-Apple platforms.

Thank you so much for the advice!

Kanji stand for pictures. 山 and 川 are very famous about it, so most japanese know. This knowledge may help you study Kanji ;) Good luck!

Learn hiragana and katakana well. Then focus on vocab slowly, try and recognise the kanji. You kinda get a feel for the stroke order by practice. Don't rush it, I know probably 100-200 kanji and its taken me a year and a half to recognise them and half their readings. Do 30-60 mins a day. Learn 2 per day and in a year, you will have about 500+ some what learnt.
