1 year!? I have been in Japan and studying for 9 years.
You need to study kanji symbols, kanji meanings, vocab all in conjunction. I still read a VERY low level.
And Hesig is amazing. There is simply no way you are going to learn 2000 joyo Kanji as an adult any other way. BUT you must apply Hesig to other methods. Hesig just put the symbol in your mind. But what is the Japanese for that symbol? You need to learn that at the same time. For me if I just study Japanese to Kanji the kanji all blend together in my mind and I never remember them for a long time. If I just study Hesig (Kanji to English) then I just know a bunch of single kanji and their English meaning which isnt all that useful. Combine the two methods and your memory will thank you. It will take YEARS! If you really really push you can probably learn all 2000 joyo kanji in two years. I am at about 1200 after starting over (from a 3 year break) and it took me about 8 months. But you slow down the higher up you go. 800 is a huge roadblock. After that your mind begins throwing out some kanji to make room and gets harder and harder to cram more in. I find that the more and more I learn, the more and more I miss and have to start over with them. At 1200 my foward progress is much much slower. So I estimate another 1 year to hit 2000.
