It's almost 77 degrees F here in Tokyo, and very pleasant. I don't feel hot, because air quality is nice during a long-term holiday week. Everybody has evacuated Tokyo. Why not enjoy staying in Tokyo? The number of COVID cases has decreased dramatically. I guest this is because a variant of the virus gradually fades out and another one is appearing a couple of months later. Simply speaking, we are in the term of transition from one variant to another one. This is a typical of the virus that is quite different from the patter of outbreak of flu. Anyway, we're enjoying early summer. Why not go out?
