I don't know the Tobira books but you could try Kanji in Context, working on your Kanji on renshuu (make some schedules, adjust your settings so you see more kanji, read lots of sentences), and try 多読 - extensive reading (without looking everything up in a dictionary). Hope this helps!
Try the 日本語総まとめ series. They're designed for the JLPT, but are pretty comprehensive and will give you lots of exercises to practice using the kanji. There are five books (kanji, vocab, reading, listening, and grammar). I'd start with the kanji book, and add the vocab and grammar books as you feel more familiar with the kanji.
If you can't find them, 新完全マスター could help, but is more advanced and would be more helpful once you learn some of the kanji.
I just want to improve my language to high level so i can one day read Japanese books and maybe be translator ,
I'm self-study student for two years now and I make a huge progress. I know it really hard thing to do without any help but I live in city that Japanese language major is not available. So i start by myself at least for now. Did You think I can do it ? Is there anything special that colleges offer for their students that i can't do it by myself ?
Don't worry about the JLPT (Japanese Language Proficiency Test) part for now.
The 総まとめ books I suggested are like textbooks and are good for self-study. They will help you progress to a higher level. I use them and have been self-study for more than ten years.
Colleges offer the opportunity for conversation practice and teacher correction. There are lots of websites that can do similar things, but someone else would know more than I do about that.
There's also the 漢字学習ステップ series (usually called the "step" books). They focus exclusively on kanji and are ordered by grade level: 10級 (1st grade/year), 9級 (2nd grade/year), up to 1級 (graduate student/professional). Search the forums, I know there are a few threads discussing them.
