In May 2022, the Ministry of Health, Labour and Welfare (MHLW) presented the following ideas regarding the wearing of masks as a measure against COVID-19 infections, based on expert opinions.

- Wearing a mask is important as a basic measure to prevent infection.
- When outdoors, masks are not necessary when a distance of at least 2 meters can be maintained between people or when rarely engaging in conversation, even if social distancing cannot be maintained.
- When indoors, if you can keep a distance (2m or more as a guide) between yourself and others and if you are rarely engaged in conversation, you do not need to wear a mask.
- Wear a mask when meeting with elderly people or visiting a hospital.
- In summer, it is recommended that masks be removed in outdoor situations when they are not needed in order to prevent heat stroke.
- It is not recommended that children under 2 years wear masks. Children over 3 years old and prior to entering elementary school are not required to wear masks regardless of their distance from others.
- Even if masks are not worn, basic infection control measures such as hand washing and avoiding the three Cs should continue to be taken.

Japan does not have a system that mandates the wearing of masks or imposes a fine for failure to wear masks.
