Would you go travel hundreds of kilometers just to get a bite of an unusual burger? According to Tokyo Walker, the residents of Kuroshio in Kochi Prefecture, Shikoku, are hoping foodies from around Japan will be induced to do just that. At a special one-day event in Ginza this summer they unveiled their katsuo tataki burger at a store selling Shikoku produce. Made with a slice of seared salted tuna, topped off with veggies, special sauce and katsuo flakes, the burger is a regular item on the menu in restaurants in Kuroshio.

Foodie tourism is a big thing in Japan: Several years back, one town was reinvigorated by an influx of tourists keen to test sanuki udon (noodles) on the basis of a popular book on the subject.

Lately, unusual burgers have also proved to be a big draw with travelers. The ramen burger, for example, invented a few years ago, has attracted tourists to Kitakata, Fukushima Prefecture. Visitors are keen to sample this original snack, which utilizes fried noodles instead of bread as the burger bun, thought recent events may, understandably, have slowed trade down somewhat.
