I've just started to teach myself.
My strategy is to follow 'Khatuzomoto's' advice over at http://www.alljapaneseallthetime.com/blog/about .
A lot of it rings true to me, though I'm not sure I'll take it as far as he has at the moment (I'm still mentally preparing).
- I've downloaded a lot of podcasts in Japanese to get used to the sound and I watch a lot of Japanese movies/drama's/anything I can get my hands on, and I rip the audio from it afterward so I can put it on my ipod and listen to it when I get sick of the podcasts/music. It's kind of like listening to a dramatised audio book;)
- I also play Japanese games on my nintendo DS (right now Lux Pain, as it it's simple and involves lots of reading) and I try to write down sentences that I pick up here and there to expand my vocabulary.
A good site for that is www.playasia.com as shipping costs are reasonably cheap.
A good site for other Japanese media is www.yesasia.com and for most products they do free shipping (at $39 and above..I think).
- I'm still waiting for a book that teaches kanji to arrive and once I've started that, the actual Japanese immersion'll start as I learn to understand more and more Japanese ^^
The book is: Remembering the Kanji by Heisig (he teaches you how to remember kanji via mnemonics ).
I also got : "The complete guide to everyday Kanji" (still waiting for it) though it's out of print now.
- I've also found some Japanese pen-pals on www.japan-guide.com and www.mylanguageexchange.com (<- you have to pay for this one).
And today I've signed up at www.sharedtalk.com (which is by rosetta stone) to find some penpals who are serious about stuyding a language.
The basic rule with language exchange partners is: you teach them a language and in return they teach you a language.
Though as long as I can't speak proper Japanese, I'm just helping them with their English.
One thing to remember is that a lot of people won't respond to you when you contact them, most likely because they get flooded by other people's e-mails... So, don't feel bad or take offense if they don't respond back.
It took me at least 30 or so e-mails to get around 5 pen-pals:P The main thing to remember is that, eventually you will have someone respond to you:)
(and of course, be careful with passing out any personal information!)
- Another great place to go to is www.lang-8.com where you keep a diary every day in the language you're practicing and people correct your sentences for you (in return you correct other people's entries).
I would save this site for when you have a grasp on basic Japanese though.
Apart from the above, I've also bought some books.
1. Japanese for Busy People.
This book SUCKS. Especially the romanized version, it's useless.
I would stay away from this one if you're serious about studying Japanese.
And I've heard a lot of other people say the same. Though these days I do use it every now and then when I have nothing better to do.
2. Japanese the Manga way
This takes a 'scene' from a manga and it explains the grammar used in it.
It's a pretty good book imo as it teaches you the polite way to say things but also the (less) informal way to say things.
And you can practice your reading by deciphering the manga:P
3. Oxford Beginner's Japanese Dictionary
This is very useful for beginners as it has lots of example sentences, which is very handy when a word is used differently than it would be in English + it's an excellent way to expand your vocabulary.
The words are in kana first and then in kanji.
Though you might outgrow this dictionary fairly soon, it's a good way to start.
One of the most important things to learning a language though, is that you practice *every day*.
Make it a habit (e.g. learning 15 new words/phrases everyday and reviewing 50) and try to apply it on as much as your activities as you can (e.g. listen to Japanese podcasts/music/etc. while doing an activity that doesn't require sound, watch Japanese spoken movies instead of English ones, scan cnn.co.jp every now and then etc.).[b]
