Business manager visa for HSP(II)-visa-holder

If I have understood the eligibility to start a company in Japan, then a foreigner must need to obtain a business manager visa for which it is needed to show at least 5 millions yen capital.

How about if someone has a HSP visa? Does it still need to obtain a business manager visa, although HSP allowed limited type of business?

If no, then to start a company that is permissible under the HSP VISA, is it possible to register a company without 5 millions yen capital?

Thank you.

if you have 高度専門職２号ビザ, it seems you can make your own company without having (changing to) 経営・管理ビザ.
5000000 yen is the rule for 経営・管理ビザ.
there is no such rule for 高度専門職２号ビザ.
you can make a company only under business law.

ask detailed information to immigration office or immigration lawyer.
ask how to make a company to an accountant or 司法書士.

Anybody can start/incorporate a company if the company meets the requirements (such as Japanese representative). Immigration would not be the correct people to ask - they don't cover those commercial/legal aspects. If you are holding a valid resident visa then you could incorporate a company relatively easily.

Just to follow-up on this statement, it is actually not correct. The statement is the wrong way around.

As part of the business manager visa you need a company and generally need to commit 5 million yen (technically that doesn't need to be as paid capital, but it is a convenient way of doing it in terms of company structure.) Companies in Japan can have a little as one yen in paid capital on formation.
