There are only four criteria for someone to be granted a visa in Japan. However, satisfying some requirements is easier than others. First, the applicant must have a valid passport. Second, the applicant must have accurately completed all necessary documents for the visa application. Third, the activities that the applicant plans to engage in while in Japan must be legitimate and meet the requirements of the visa. Finally, certain people defined in the Immigration Control Act (such as those with a dangerous infectious disease) can be denied a visa to enter Japan.
