A friend of mine and her Japanese bussiness partner are offering moving service from home to port, from Hokkaido to whole over the world, as the website claimed :)
Here is the website --> http://www.ace-solution.com/
The service is suitable for foreign student/worker who plans to return to home country for good.
They also sell used cars for those who are interested.
I myself bought a second-hand cute Kei-car from them, and it was no hassle since she can speak English, Malay and Japanese. Everything was clear. Just quote your budget, car specs and they will search for the matched one.
