How would someone move from california to japan?

Question:

Like my plan is to move to japan when I'm like 20, I'm 16 now. I really love to go but I don't know what I would need to know. Obviously I need to know the language but like the cost of stuff.

Answer:

Unless you are independently wealthy you are going to need a job. That means getting a work visa which will require a college degree and a job offer from a company. So what you really need to know right now is that with your current plan, you will not be moving to Japan. You can,however, come on a tourist visa for 90 days.
