Do I need to book a hotel together to apply for a Japanese visa?

You must provide an order for the whole machine wine, but it doesn't matter whether you decide or not, because most agencies or travel agencies now offer a set meal for the whole machine wine. In other words, the travel agency will order machine wine for you, and they will cancel it after signing it. this is nothing to do with you. Just wait until you sign the bill, but the visa fee will be more expensive. Of course, you can make a reservation in advance.
