Amsterdam Airport Schiphol in the Netherlands. There were quite a lot of people coming and going.At Helsinki Vantaa Airport, there was a booth in front of the exit, where I was asked to show my vaccination record for the first time. I launched the vaccination certificate app issued by the Japanese government and displayed the QR code, but for the life of me I could not get the machine to read it. Eventually, after verbal communication with the staff, I was able to enter the country safely because I had completed the three vaccinations in February of this year, but I was puzzled for a moment when the QR code did not respond. In Switzerland, which he visited later, he entered the country without any confirmation. Further, when we left Switzerland for France, we were not checked for vaccination records, and we did not have an opportunity to present the “written oath” that we had prepared because we were told that it was required for entry into France. No change in the hassle upon entry into Japan, and a double hassle in obtaining the test results The biggest challenge was and still is when returning to Japan. Within 72 hours prior to departure, one must take a PCR test and prepare a written document in the format recommended by the Japanese government. The method of testing and even the format of the test are specified in detail, and failure to submit the necessary documents may result in deportation, even of one’s citizens.
