There might be some documents that you will have to forward though. It was quite some time now when I was processing my last visa, but I know that Japanese Immigration requires documents with a date of issuance not exceeding 3 months. For instance, the birth certificate. You will have to ask your city hall to issue you a new copy of the original. This is what you need to send. I am sure that the company that is processing your visa should tell you precisely what you need.
