My family and I have recently embarked on a vacation to Japan. The trip was much easier than I thought it would be with 3 young children. There were some very interesting changes though with Swine Influenza spreading. We had a long layover in Taiwan and when we left the aircraft, there were a very good deal of people wearing masks in the airport. Probably a good idea even without an influenza scare since there are people in the airport from all over the world. Our arrival in Japan, however, was even more involved. Before passing through customs, we were required to fill out a document regarding our recent health and travel. Since we were coming from the U.S. we were further required to undergo a simple health check. Apparently on some flights, the health inspectors actually board the flight and check people before allowing anyone to leave the plane.
