Take basic measures to prevent the spread of infection such as washing hands, avoiding the "Three Cs", ventilating and Effective Mask Use when necessary. We also ask that you continue to practice teleworking.
Effective Mask Use

- Wear a quality-certified, non-woven fabric mask if possible.

Frequent hand washing and sanitizing
- Wash your hands and sanitize after touching shared items, before and after eating, and after using public transportation.

Avoid the “Three Cs”
- Maintain physical distance from others.
- Ensure good ventilation indoors.
Prevention measures in the workplace/school

- Telework if possible.
- Refrain from commuting when you show symptoms such as fatigue, fever, sore throat, anything different than usual, etc.
Continue to take basic precautionary measures, even after receiving your vaccine.
Five situations that increase the risk of infection.
Through analysis of prior outbreaks, behaviors and circumstances associated with a high risk of infection have been identified. It has been found that the spread of COVID-19 infection spreads primarily through clusters. Based on the findings from cluster analysis, the Subcommittee on Novel Coronavirus Disease Control has compiled a list of five situations that increase the risk of infection.
Situation 1 Social gatherings with drinking alcohol
- Drinking alcohol improves mood and at the same time decreases attention. In addition, hearing is dulled and it leads to speaking in a louder voice.
- The risk of infection increases when large numbers of people are in a small space for a long time.
- In addition, sharing glasses and chopsticks increases the risk of infection.

Situation 2 Long feasts in large groups
- Long-term meals, dinner receptions, and drinking alcohol at night increases the risk of infection compared to a short meal.
- The risk of infection is increased by eating and drinking in a large group of people, for example, 5 or more people, because in groups you have to talk louder and droplets of saliva spread more often.

Situation 3 Conversation without a mask
- Talking at close range without a mask increases the risk of airborne or micro-droplet infection.
- Cases of infection without masks were observed during gatherings at daytime karaoke.
- Please be careful when traveling by car or bus.

Situation 4 Living together in a small limited space
- Living together in a small limited space increases the risk of infection because the enclosed space is shared by several people for a long time.
- There have been reports of suspected infections in common areas such as dormitory rooms and bathrooms.

Situation 5 Switching locations
- When you move to another location, such as when you take a break in a workplace, the risk of infection may increase due to the feeling of relaxation and changes of the environment.
- Suspected cases of infection were identified in break rooms, smoking areas, and changing rooms.

Points to keep in mind during dining
