People call Heisig an outlandish idea? Oh, it's Mike, nevermind...
Heisig is the best thing you can do if you want to surround yourself with Japanese. You might not always be able to get Japanese voices into your head at every time of the day, but text should always be available, and Heisig unscarifies text, so you can actually start reading very quickly even if you don't understand things.
And to me, reading without understanding is one of the best things you can do to get to the part where you read with understanding.
I really didn't like Heisig. I found it a way for foreigners to get the gist of kanji without actually knowing them or using them.
My beginner study strategy, that worked for me:
-Japanese for Busy People (Genki or Minna would be a better substitute, since they have much less business involved)
-Pimsleur CDs. Very good. Still a little business-oriented, but it gives you great Japanese to slowly listen to, lots of repetition, and convenient on an iPod
After a year:
-Kids drill books for kanji. I started with Kanji Kentei 10 kyu (book intended for a 6 year old). Learned the first 40 comfortably in a few months. Over two years, I learned up to 6 kyu, which set me up with the kanji of a 10 year old. This is most of what you need for actual life in Japan, though doesn't cover everything you'll find in books or manga.
-I studied texts for the Nihongo Noryoku Shiken, the international test of Japanese. This dramatically opened up my vocabulary and grammar comprehension.
After two years studying like this, I met my wife, and have been speaking in Japanese daily ever since. At the end of the first year, I was still talking like a child, and at the end of the second, I was able to have conversations with people relatively comfortably, though I had to describe some words that I didn't know.
What's going to work with you is not going to be the same as with me. But you need to set smaller, more achievable goals. I don't enjoy Japanese TV at all, so I don't watch J-dramas, but when I watch TV, it's a hell of a lot harder to understand than daily conversation. I think you're looking at years to get to that level, so setting a short term goal is better.
I'd recommend something like Minna No Nihongo, plus audio study with something like Pimsleur, and learning hiragana and katakana. After one year, see if you're ready to go to the next level.
Good luck!
