If you want to teach English in Japan for a company which hires from overseas, you will be tested on your English ability. You will be required to fill out an application, cover letter, and likely write an essay as well, and these will be carefully scrutinized for any mistakes in spelling, grammar, etc.

Should you get through with your application/cover letter/essay, you will be interviewed on the telephone. The interviewer (a native-speaker/teacher) will listen carefully to your English speaking ability; he will judge your accent, diction, pronunciation, and intonation.

If you get through the telephone interview you may be interviewed once more in-person before actually being hired. At the personal interview you will likely to be given a timed test on your English knowledge, and you will have to make up a one-point, demonstration lesson. If you get through these, you will probably have to prepare an actual teaching lesson, and you will be judged on the quality of that lesson.

Using "internet English" says little more than that you are either too lazy to write in complete sentences, or that your English ability is poor, or both. If it's a result of laziness, an employer might be afraid that this laziness will be exhibited in the classroom as well. So lose the internet-speak and write like someone who actually knows how.

There is a lot of competition for teaching jobs in Japan right now, so employers can afford to be much more picky about who they hire. For the larger schools or JET, perhaps 1 person out of every 300 who applies will actually be hired. Do you think your English is better than those 299 other college-educated applicants? From the content of your posts, I don't think so. Try to write something coherent and prove me wrong.
