   - (Number of deaths)

 = 306 - 472  - 1

 = -167 people


Estimated total number of infected people in Tokyo as of today

 = (Number of positives)

   - (end of medical treatment period such as discharge)

   - (Number of deaths)

 = 126,284 - 120,485 - 1,804

 = 3,995 people


*Tokyo currently has 12 facilities for infected people
 (Capacity of 5,048 people)


* A hospital in Tokyo has secured 4716 beds (+332 beds for critically ill patients).

(Because the deadline for the number of new infections on the day is from 9:00 am the day before to 9:00 am on the day)

*Graph of the number of newly infected people in Japan as of yesterday

(* This bar graph is up to the previous day, so today’s red bar (handwritten) is on the far right, but it’s about this …)


(*”Since the graph shows only the numbers up to the previous day, I handwritten the rightmost bar, but this is about it!”)











Today was a day with little news like usual Saturday-Monday, so today I made my own data!


Yes, it’s the usual “hobby world” lol




By the way, in Tokyo recently, the number of infected people is increasing, and the infection rate of young people in their 20s and 30s, which had been low, is increasing again …!



I introduce it every day in this “Summary article” in ↑, but today I summarized it in a graph! ↓





If you look at the graph like this, you can see how the percentage of people in their 20s and 30s has increased rapidly recently …!

The government, local governments, and news sites say that “If the number of young people infected increases, the number of infected people in the entire area will increase,” so I think about it, I’m only scared …!



And from the graph above, you can also see the following!

①Although the number of infections among young people in their 20s and 30s has increased abnormally, the infection rate in their 30s and 40s has hardly changed.

②There is almost no change in the infection rate under the age of 20.

③The infection rate of elderly people (60 years old and over) has decreased considerably.
 =Infection in hospitals and facilities for the elderly is suppressed(?)



And if you look at this “age-specific ratio” in more detail …


Not as before, even if you graph the infection rate every 10 years (by generation),

the ratio of the generation that is said to be the main generation of infection (30s (purple), 40s (light blue), 50s (orange)) has not changed so much, but only in the 20s The infection rate is rising abnormally …




Looking at the actual number of infected people by age as well as the ratio,

the number of working generations in their 30s, 40s and 50s has increased to some extent, but the number of infected people in their 20s is  jumping up abnormally…



Apparently, I feel sorry for 30s to categorize them as “20s-30s” … (dry laugh)

(Because the infection rate in the 30s has hardly changed)



As you can see from the population distribution by age in Tokyo,↓

(*東京都の人口は「1,374万人」、7割近くが23区在住 – シニアガイド)



If everyone is doing the same thing, the number of infected people should be in the order of
“40s> 30s> 50s>
}in terms of population ratio …




Thinking this way, you can see “how human behavior is related to the infection situation”!



There wasn’t much news today, so today I thought about the infection rate by age!



It should be remembered that many people in their twenties are refraining from doing so, and many people in their thirties and over are hanging out.

I hope everyone can somehow turn to the same direction and end COVID-19 infection disease!








And this article↓


How long time the materials such as paper, cloth, plastic, etc. need to eliminating the risk when coronavirus is attached, and how effective disinfection is.

If you are interested, please take a look!







And here’s a trial calculation of how many people in Japan are actually receiving medical treatment.


(Number of people infected nationwide) 509,711

+ (Number of hospital discharges ) 9,446

+ (Number of hospital discharges ) 466,575 

= 33,690  people ( -111)  ← being treated

 *()=increase  from the day before



(If it is exactly as announced)

For those who are undergoing medical treatment nationwide are…

there are many days when the numbers increase this week too …




Priority vaccination for the elderly will finally start tomorrow in Japan!

Until now, it was the stage of priority vaccination for medical staff, so it seems that vaccination will finally move to the next stage since the start of vaccination in late February!



The first day, tomorrow, April 12, there will be about 120 locations nationwide, and it is expected that all elderly people will be able to receive the vaccination twice by the end of June this year …!


It is said that there are about 36 million elderly people aged 65 and over nationwide, so it is calculated that about 40 million people (including medical staff) will complete vaccination by the end of June!


I think the pace of vaccination will accelerate further, but if vaccination progresses at the same pace as before …


・Japanese population = about 120 million
・40 million people in 4 months from late February to the end of June

 = It took four months for one-third of Japan’s population to finish vaccination


→It will take an additional “4 months x 2” period from the end of June until the remaining two-thirds of Japanese are vaccinated.

 →”4 months x 2″ = 8 months

  →8 months after the end of June … The end of February next year ?!

All Japanese people will be vaccinated at the end of February next year! ?? ?? !! ?? !! !! ??


Hmmm, I shouldn’t have calculated …! Lol



With that in mind, I have no choice but to accelerate vaccination to the maximum …!

I hope it’s over at least by autumn … (dry laugh)





Please be careful when you go out!
