Too many things all at one time!

- The manga course in Kyoto, is that a college? Then you need to apply with the school, get accepted (any exam?), pay in the tuition, and with the help of the school apply for a Student visa. If it's a school that is classified as a technical college/school, the visa category might be Pre-college visa. (If you don't speak/write the language fluently, you might want to attend a separate course before being able to attend the manga course.)
- After the course is finished, you need to find another kind of visa to stay in Japan.
- Unfortunately, you need to be employed by a Japanese company to be eligible for a work visa, you will not be able to simply stay; if you produce manga on your own and actually get paid for it, you need some kind of work-permitting visa.
- For opening a cafe on your own, Business Manager/Investor visa status would be the applicable one, but I have heard that the requirements are quite strict and this visa is difficult to obtain. Buying properties is fine if you have the cash, but you would need to have permanent resident status to qualify for a loan from a Japanese bank.

You should take things one at a time... :)
