Most Japanese visas regulate the type of work that the visa holder is allowed to engage in. For example, a foreign resident of Japan with an Instructor visa would not normally be allowed to also have a side job as a cook. However, by making an application to the Ministry of Justice, it may be possible to waive these restrictions.
There are three general types of registration for property in Japan. The first is the system of registration for immovable property or real estate. Registering ownership of real estate will clarify not only the ownership rights but also what types of rights are included in that ownership.
When establishing a company in Japan, the founder will be required to register an official seal for the company. Stamps or seals are commonly used in Japanese business as an alternative to signatures to authorize documents. Officially registering the seal will legally bind that specific design to the company and any time that seal is used it will be presumed to be an official recognition by the company.
Certain patented inventions may require approval from a government agency, such as those regulating consumer products, medical devices or food, before they are allowed to be sold to the public. This period of waiting for approval unfairly cuts into the patent term and lowers the profit an inventor can expect to make. Therefore, patents in this situation may be extended for a further period of up to five more years.
