In principle, the answer is no.
The system for accepting foreign technical interns is created for the intention of taking over the skills and knowledge acquired in Japan so that they can make it available in their home countries, and contributing to the development of industries in their countries.
The purpose is of making international contributions through human resource development.
The purpose of this system is to try to bring technology, skill and knowledge acquired in Japan to home country and to make it available in your home country.
Therefore, for example, you will not be allowed to start business, apply for investment management visa and continue to live in Japan, because this action will differ from the original purpose.
