The number of “papers” given to me at the airport when I returned to Japan was slightly less than before. The red paper is a “negative” certificate.Arrival in Japan was at Kansai Airport as before. Last time, it took nearly three hours for the series of confirmation and antigen testing, but this time, I was able to leave the arrival gate in one and a half hours. Although the number of confirmation booths remained the same, the fast-track system using MySOS seemed to have speeded up the confirmation process. However, it took over an hour to get the test results, and we were kept waiting. I thought it would be smoother without this waiting time. Moreover, the antigen test was still inaccurate. With more and more countries not even having pre-departure inspections, we wondered how long they were going to continue to do this. I appreciate that the introduction of the fast-track system has made the waiting time faster, but it requires the use of a smartphone. Moreover, the app MySOS froze and was temporarily unusable. The number of booths, human checks, and “paper” is still alive and well, even if slightly reduced.
