The Saburger is a portmanteau of "saba" (mackerel) and "burger," pronounced "Sabaagaa" in Japanese. The chewy bun is made using ground rice, and sandwiches slices of fresh tomato and lettuce along with a slab of fried mackerel caught off the coast of Hachinohe City in Aomori.

This burger was developed though a collaboration between students at Hachinohe University and local restaurant Hachinohe Saba-no-eki, where Saba-no-eki means "mackerel station," giving a clear indication of the restaurant's specialty.

Yakisoba (fried noodles) with potatoes is a representative local dish of Ashikaga City, Tochigi Prefecture. This burger sees it placed between delicious bagels made with local flour and yeast from the region's famous Tochiotome strawberries.
