Financial situation of your business and extension of your status of residence
Depending on financial situation, your business will show loss and it is not serious problem.
However, if your business shows loss for two years in row, immigration office will inspect your business prudently.
If the amount of retained earnings ( Joyokin = accumulated profit ) in your company is less than zero and it damaged shareholder’s equity, it is problem.
You need to provide detailed business plan to solve serious financial situation.
If there is not any sales amount, it means your business does not have any substance and it should be difficult to extend your status of residence in Japan.
