Return to Novel Coronavirus (COVID-19)

Preventing infection

Please practice cough etiquette and hand washing

Avoid going out if you have cold symptoms. If you do have to go out, please wear a mask.



What are the 3Cs & 5Situations?

"5 stuations" that increase the risk of infection

Situation1) Social gatherings with drinking alcohol
Situation2) Long feasts in large groups
Situation3) Conversation without a mask
Situation4) Living together in a small limited space
Situation5) Switching locations


Avoid the Three Cs

"Closed spaces with poor ventilation," "Crowded spaces with many people nearby," and "Close-contact settings such as close-range conversations" are particularly common contributory factors in outbreaks.

Please avoid group gatherings in poorly ventilated spaces crowded with people.


Our requests to prevent the spread of infection

Let's all do what we can to the best of our ability - for ourselves, for others, and for our loved ones. This is the approach that our future will be built upon.

Request 1:
Avoid the Three Cs (crowded places, close contact settings, and closed spaces). Common factors in outbreaks are closed spaces with poor ventilation, crowded spaces with many people nearby, and close-contact settings such as close-range conversations.
Try to avoid going to such places. If you must go, make sure that you wear a mask, ventilate, avoid talking in a loud voice, and avoid having conversations with people within arm's reach.

Request 2:
Please practice hand washing and cough etiquette (for example, cover your mouth and nose with a mask, tissue, handkerchief, sleeve, or inner elbow when coughing or sneezing).

Approximately 80% of those infected with COVID-19 are reported to present only mild symptoms and many recover. However, the risk of developing severe symptoms is reported to be high among the elderly and people with underlying diseases.
We request your cooperation to protect yourselves and your loved ones.

Let's adopt the New Lifestyle

To provide a more vivid image of the New Lifestyle under COVID-19, we present examples of some of the practices that we want people to adopt in their daily lives. These practices are based on recommendations issued by the Expert Meeting on the Novel Coronavirus Disease Control.


Beware of heatstroke!

We must all practice the New Lifestyle by embracing three basic measures for preventing the spread of COVID-19: keep physical distance from others; wear a mask, wash your hands, and practice cough etiquette; and avoid the Three Cs (crowded places, close contact settings, and closed spaces).

As summer is approaching, we hope that you will take care to avoid heatstroke. We have put together some key points for heatstroke prevention actions, including wearing a mask, using air-conditioners, moving to cooler places, and promoting daily healthcare.
