While the infection of the new coronavirus continued, the Institute of Defense examined the materials kept by the former Japanese army about the Spanish cold that was epidemic about 100 years ago, and documents like calling for the wearing of masks as well as now are found. It was found and will be published.

About 100 years ago, the world-famous "Spanish cold" had three outbreaks in Japan from the fall of 1918 to the spring of 1921, killing about 390,000 people, according to the Ministry of Home Affairs at the time. I am recording.

If the Defense Research Institute examined materials stored by the former Japanese Army to see if it could be used as a countermeasure against the new coronavirus, a record was found in the diary of the first light cruiser "Yahagi". Immediately after leaving the port of Singapore, Yahagi spread throughout the ship, killing 48 people (more than 10% of the crew) and thoroughly disinfecting the ship at the next port of call.

Also, according to another document that the Ministry of Internal Affairs of Japan called on the public to prevent infections, use a handkerchief to keep people out of places such as movie theaters, to wear masks on trains, and to cough in front of people. I was asking for the same response as I do now, such as covering my mouth.

“We felt that the common sense of 100 years ago and the common sense of today are not so different in the sense that we will not spread the disease,” said Naoki Sugano, director of the Defense Research Institute, who examined the materials.

These materials will be open to the public for those who have booked for viewing at the Defense Research Institute in Ichigaya, Tokyo from the 16th.
