The first question you need to ask yourself is, Why would anyone hire you when they can hire a citizen/native Japanese speaker who can perform the same job just as well? What can you bring to the table as a foreigner with basic Japanese trying to work in a heavily technical field? Because of your job, you'll not only need to learn just standard Japanese, but also all medical/technical terms that come with working in that type of job, which is a long road ahead. I don't mean to sound like a downer, but this is something a lot of people don't realize. There are plenty of people here who can do the same job with no language/cultural/citizenship barrier.
