On 5th June, 2021 The Narita airport
At 8:00, I got my suitcase that I send it before. After that I went to check in counter. My documents for departure were confirmed. It took about one hour. At about 9:00, the staffs understood what I prepared my documents. They went to back to check the documents are permitted or not. After about ten minutes ago, they came back and my documents are permitted and I can get the flight. My first and the most important point was safety cleared!
