I have 4000+ words from Core2K+6K on my vocab deck, just so you have an idea of where I'm at. I don't do sentences.

I don't actually immerse in a lot of japanese, mainly because I don't quite feel it's helping.

I can read manga with acceptable comprehension as long as it has furigana. I do it with Yotsuba and Naruto at the moment. I accept suggestions BTW . (Recently I bought Blood+ but I haven't started reading it yet.)

My listening comprehension is a bit worse than my reading abilities... I seriously need to improve it. So I chose to watch a long ongoing anime without subs, this way I'll eventually catch up with the story even if I don't get it at first. The options I thought of were: Naruto (I dropped it at episode 140 some time ago); One Piece (lots of good feedback); Fairy Tail (not very long now but seems very appealing and I absolutely love the OP); maybe Gintama, Bleach... (Always open to suggestions).

Now to the questions:
Do you think I should read other stuff instead of manga? (And please throw in some suggestions).
What do you think of my idea of watching long raw anime? Should I watch doramas instead? Or maybe anime I have watched in the past (DB for example is big enough to keep me busy)? Japanese TV (though I don't think I would understand more than 20% of it at MAX)?
Won't watching or reading interesting stories eliminate some of their potential? For example, if I had played 999 (DS visual novel) or Ever17 in japanese they probably wouldn't be my 2 favorite games of all time, as I wouldn't get the plot twists. And even if I played them again with full comprehension in the future they would no longer have the same impact.
What do you think of the options I thought of? Do you think Fairy Tail\Naruto\One Piece and Yotsuba\Naruto are good anime and manga respectively for what I want?
And finally, not a question but please hit me with whatever suggestion you feel like giving, I'll seriously appreciate it.

Sorry for this enormous text and for asking so much of you.
Thank you in advance.

For reading, just do whatever you enjoy. You could try [url=http://forum.koohii.com/showthread.php?tid=7074"]yomi chan[/url] for reading with anki and get some book recommendations from this thread. Try reading a book, if it's too hard then leave it and try again later.

To keep my spirits up, I have a series of books that are above my skill level. Once in a while, I open one or two to find out how I'm doing.

Yesterday, I opened one that I thought was WAY above me and it turns out I can read it pretty well! That's a huge ego boost.

Anyhow, my suggestion is to pick things that you -want- to read and have them around. And in the meantime, pick things that seem interesting and on your level. If you can read Naruto, then there's quite a bit on that level to explore. Just about anything from the Shounen Jump magazine is good. コロコロ had a lot of really easy stuff, but only a little that was interesting. ("I'm Galileo" comes to mind as an interesting one.)

Doraemon is fairly easy to read, if you like it. Personally, I find some to be better than others. The scifi-ish ones are usually pretty good, but the fantasy ones are really lacking. IMHO.

As for listening, I really suck at it, so I don't feel confident giving advice there, other than to get a language partner.

I have the same problem with "ruining the experience for myself." Its like I'd like to wait until I know I'm good enough to enjoy it without having to worry about missing things. So I put off reading a bunch of things, waiting until I "got better."by that time my interests had changed, and I still probably wasn't "good enough" to get it anyway. In the end, I ended up missing out of any sort of experience, just by waiting until I could get the "full" experience.

If you want to read/watch/play something, just do it. If you find yourself struggling, and you literally can't do it, then stop; it's above your level. But if you can rough it out, understand it, and maybe even learn something from it, then continue on. Maybe you won't get the "full experience," but it's better than no experience. And hey -- you'll come out of it with a few new vocab words and understanding, can't beat that.

Tl;dr: readthings that are difficult for you, but not impossible. You'll still get a good experience out of it.

You can watch a long anime if that's what you like. My only suggestion would be to take it maybe ten episodes at a time. Watch them on repeat. Pause and listen again. a 20 minutes show can sometimes triple if you are actively listening. I have only done this once. I mostly watch shows on loop passively approximately 10 shows at a time. and as I keep watching them I pick up more and more. Also I think keeps it in real time because when you speak to people here in Tokyo it is not gonna play like a script (although if they find you boring sometimes it does. "Where you from?" "Amazing I want to go" "whats your job" "student" "Wow. Why can you speak japanese?" "I was born awesome" "へ〜〜　Do you like japanese girls?" )

I'll tell you in the beginning phases, I was obsessed in becoming ultra fluent in Japanese. I was stressing myself out by doing so much srs reps, listening so much times and diving into reading that made my head spin at times. There were times I was close to just giving up and never come back into Japanese. So I relaxed and took a different look at it. It was to have fun, srs fun material, listening to fun stuff and read fun material. It was only when I dived into things that were interesting to me, that I discovered how it really works.

A lot of people will say dive into grammar,context,sentences and a whole lot of other things(don't get me wrong, these are vital and necessary). But if you make these fun by adding fun material and making the reason why you learn is: fun. Then you'll get far(long-term).

Another thing I should say is: expect huge fails and criticism at times. But aside from all this, I still kept going and now I'm feeling the benefits. I can dive into native material,read,listen,watch and have the ability to decode things easily in Japanese. I went from zero listening to reading to 90%+ and sometimes 100% at times. Now this is only the half way mark. Speaking and writing are vital too but if you think about it, the things that were once hard will become easy. But you will have to get by that barrier that prevents you from excelling in all this.

So relax, have motivation to learn(it's fun and interesting is why I learn), put in the time.

Thank you very much for all your answers.
