Changes in COVID-19 positioning after shifting to ”Category 5″

Effective May 8, 2023, the status of new coronavirus infectious diseases under the Infectious Disease Control Law has been moved from “category 2 equivalent” to “category 5”. As a result, the government will no longer be able to restrict the behavior of individuals, and infection control measures will be at the discretion of individuals. In addition, the cost of tests and treatment, which was previously covered by the government, will now be borne by the individual.

Changes after the transition to “Category 5”


In principle, testing is performed at your own expense, whether at a medical institution or using a test kit.

Medical Expenses

As with other illnesses, 30% of medical and testing costs are to be paid out-of-pocket (10% for those over 75 years of age). In addition, after testing positive, support for inpatient and outpatient medical expenses will no longer be provided, and patients will be responsible for their own medical expenses from now on.


Until September 30, in order to lighten the burden on patients, a portion of the amount to be paid out-of-pocket may be covered by public funds. Please check the procedures required in some cases. The continuation of both of these programs after October has not yet been determined.

When Infected or Worried about Infection

When Infected

Work or school

Follow the instructions of the company or school you say you are at.

If a family member tests positive

Even if a family member is infected, he or she will not be identified as a person in concentrated contact with the disease, and in principle, there is no need to refrain from going out.
Please take precautions against infection such as wearing masks and disinfecting frequently, and take care of your own health.
As for going to work or school, please check with your company or school.

Going out

Whether or not to refrain from going outside is a personal decision, but it is recommended to refrain from going outside for 5 days after the onset of the disease and until 24 hours have passed after recovery.
Also, until 10 days have passed after the onset of the disease, it is advisable to avoid spreading the infection to others around you by wearing masks and avoiding contact with people at risk of serious illness (elderly, pregnant women, people with underlying medical conditions, etc.).

If you are concerned about infection

If you have symptoms such as fever, consult your family doctor, a local medical institution, or the Gunma Medical Consultation Call Center. Please be sure to contact the medical institution in advance of your visit.
