"how can i learn japanese language???"
Bluntly put, study.

As for your work and living. Seriously figure this one out on your own. We can't just point you to a website and say "sign up here and you have work and you will be ready to move in a second"

What we can say is, that with your current japanese skills, chances are you won't be finding any work or getting a work visa.

Your current plan is as well thought out as the blueprints of a rocket drawn by a child.

If anyone has been in the same boat as you -- being a clothing designer planing on moving to japan without knowing the language -- it would be interesting to hear. One thing you have to keep in mind, you can't just copy the success of someone else, hard work and determination will pay off.
