Yes, IMO the easiest way to 'learn' the kanji is Heisig's book "Remembering the Kanji", along with an Anki deck to review daily. I 'learned' 2000 kanji this way in 3 months, with a daily time investment of about 1 hour. There are plenty of pre-made RTK Anki decks. The reason I'm putting learn in quotation marks is because afterwards you need to reinforce them in context, ie by learning vocab and doing tons of reading (there's a term called 多読 which means it's not the quality of the material or even your level of comprehension, but just the sheer amount of pages you read).
