Sponsorship through your own BV
Most founders use the highly skilled migrant scheme. First, you incorporate the BV remotely, usually within one week once all documents are complete. The BV then becomes a recognised sponsor and employs you at the required salary. Your own company sponsors your residence permit. See how kennismigrant hiring works. For a young company, you add proof of funding to the application. Make a salary plan that the BV can pay, so the figures stay realistic. See founder salary options.
Other options
The start-up visa is for founders who still have to set up a company. You get one year to build the business with a recognised facilitator. When the business shows results, you switch to the standard permits. See how it compares with other countries. Under the working-holiday scheme between Japan and the Netherlands, people under 31 get one year of free access to the labour market. This is one way to test the market before you set up a company. Graduates of Dutch and other listed universities can also use the orientation year. See the orientation year explained.
Compare the Netherlands with Ireland and Germany on tax, substance, running costs and time. See setting up a Dutch subsidiary for a foreign parent company.
The order of the steps
Arrange the company first, then the permit, then the relocation of your family. The notary sets up the BV while you are still in Tokyo. Once the BV is registered, you apply for the sponsorship. At the same time, you plan the relocation of your household, including schools and the community in Amstelveen. See the wider Japan-Netherlands guide and the family relocation guide.
