Yes, there are special measures announced on June 1, 2020 by the Immigration Services Agency for foreign nationals holding working visa statuses who have had their employment affected by the COVID-19 global pandemic situation. As of December 2020, these measures are still active. There are four categories of people who would be eligible for these special measures:
Those who have been notified of the termination of their employment, or the non-renewal of their employment contract and wish to look for work.
Those who have been ordered to standby and wish to return to work.
Those who have had their work days or hours reduced, and wish to continue working.
Those in a situation equivalent to the above.
People who fall into one of the categories listed above will be permitted to remain in Japan using their current visa status. If there is less than 1 month standby remaining, or the foreign national is working reduced hours, in the case that the majority of their total work at the company was with normal work hours, they would be able to apply for a 1 year extension of the current status. They will also be allowed, with permission from their current employer, to apply for a Permission to Engage in Activity Other than that Permitted under the Status of Residence Previously Granted (part-time work permit) in order to supplement their loss of income. The duration of the permit will be 6 months or the expiration date of the visa status, whichever comes sooner.
In addition, those whose status is expiring soon would be eligible to apply for a Designated Activities – Job hunting visa status as well as a part-time work permit valid for 6 months.
When making the applications above, it will be necessary to submit documents from the employer/former employer to provide proof of the circumstances.
