Japanese Native Level.

Please I have a question of the "Japanese: Native Level".
I had started to search IT-jobs, after I finish my master here in Japan. (specially in Ecentral)

My question is:
When some job is posted as "Japanese : Native Level" it means "NO FOREIGNERS. ONLY JAPANESE PROFESSIONALS"?.
I'm asking this, because I'm studying really hard for the JLPT-1 , in the assumption that "native level" means having at least the JLPT-1.
Please any comment will be appreciated.

In my experience with such job ads, it means that the speaking ability of the applicant must be that of a native Japanese person. This can be achieved by foreigners, but level 1 of the JLPT would be the absolute minimum level required for such a job.
If your level is not that of a Japanese, the chances of being hired would be extremely slim.

JLPT 1 is considered "business level" rather than "native level" in recruiting lingo here. "Native level" does not mean "no foreigners" because there are actually non-Japanese who speak Japanese at a native level.

I have JLPT 1 and I do not consider my Japanese to be "native level" as I still quite often come across kanji I can't read and vocab I am unfamiliar with.

However, if you have experience working in IT and can offer valuable skills to a potential employer, they may decide to offer you an interview with just JLPT 1. If you are only just starting work though it's unlikely that employers who ask for native level Japanese will consider you.
