Wants to move to Japan

You cannot simply change visas in Japan.

Can you give me some guidelines as to how to go by it when I get to Japan. Thanks

You cannot change a tourist visa to a work visa.  You have to find a job and your employer will arrange visa for you.

It is almost impossible for expats to get work in Japan unless you have a specialized skill that no Japanese person can do.

What sort of work are you looking for. What specialist skills do you have. How much work experience have you had.

Do you speak Japanese. If not then it will be virtually impossible for you.

Thank you very much for the elaboration you have done for me.
For now I think I can make my own decisions about coming to Japan with what you have said.
Once again , thank you very much

Hello Seth,
Nice to meet you. I am a Ghanaian, on  long time `Permanent resident` status here in Tokyo. You asked if you  can come visit here on a tourist visa and change to a work visa?
In the first place, changing from tourist visa to work visa (generally) is very difficult (maybe impossible).
In any rare case where it may be possible, maybe, some factors eg your education background & Tech skills ( university,college,special education etc) will be a major factor. Please consider all these before you make any move.Feel very free to ask questions about life here  (generally) and I hope you`ll get to learn and know a little better. have a good day.
