Do travel agencies have to book air tickets and hotels to travel freely in Japan?

Of course not. If you sign, book a hotel from booking and book your favorite airline. Print out the order and send it to the travel agency for signature. If the embassy randomly checks the electronic sound (there are very few single signs, and the electronic sound is basically signed more), it must be said that the machine wine was ordered by the travel agency, not by itself. In fact, the drinks on the plane are your personal choice and have nothing to do with the travel agency.
