When a visa application is denied in Japan, it means that there was some critical flaw in the application or that the applicant did not meet all the requirements for obtaining a visa. Therefore, reapplying immediately without making any corrections or changes to the application will likely result in another denial. Rather than immediately resubmit the same application, it is much more productive to review the denied application and attempt to fix any problems or weaknesses before resubmitting.
In 2012, the Ministry of Justice, Immigration Bureau introduced a new system for certain highly skilled foreigners to obtain Japanese permanent residency. The new system is a points based system that gives preference for higher levels of education or salary. Under this system qualified individuals are given preferential immigration treatment such as the ability to obtain permanent residence faster than other foreigners.
One of the requirements that foreign nationals must meet before being allowed to naturalize as a Japanese citizen is that the foreign national have a very basic level of Japanese language ability. The way the foreign national can prove that he or she meets this requirement is by taking a simple Japanese language test as part of the naturalization process.
Permanent residency allows a foreign national to stay in Japan legally without having to worry about renewing a visa every year. In addition, becoming a permanent resident also lets the foreign national work in any field, not just the industry specified on his or her visa.
