One of leading foreign entrepreneurs is Gengo.
However, please note that there are many foreign entrepreneurs in Japan.
The founder of Softbrain, a listed company in Tokyo Stock Exchange, is Chinese.
Thus, I still believe that even if you cannot find any solutions to raise the fund due to the economic circumstance of your home country you might find the solution in Japan and can have listed companies. There are many obstacles for you to find exits such as IPO, but it is worth to try.
