Travel has historically been difficult in Japan. In medieval times, one had to request a special travel permit from the governing authorities to be able to travel. Although travel was limited, snack shops for hungry travelers was an unmistakable part of the premodern landscape. Today this tradition endures. Japanese people can travel freely, yet they most often take very little time off work. In order to make the best out of a short vacation, Japanese tourists will take many pictures of their trip and purchase local food that can be eaten on the spot or at a later time. In this way, tourism and food are inextricably tied to each other in Japanese culture. While travelling in Japan, it is worthwhile to try to discover the different regional foods available.
