Starting tomorrow, August 24 (or today if you live in Japan), MOS Burger in Japan will be serving regional burgers and hot dogs at locations in the regions the dishes represent, created by MOS employees from those regions. None of the "burgers" are beef based—they're all made of chicken or pork—but they still sound tasty. Here are the sandwiches for ¥320 (about $3.75) each:

Zangi Burger: Available in the Hokkaido, Tohoku, and Niigata regions. According to blog Washoku, zangi is deep fried chicken flavored with soy sauce and garlic. In this sandwich it's topped with a mix of Sendai miso and mayonnaise.

Sauteed Pork & Ginger Burger: Available in the Kanto, Koshin and Shizuoka areas.

Minced Iberico Pork Cutlet Burger: Available in the Chukyo, Hokuriku, and Kansai regions.

Mentai Toriten Burger: Available in the Chugoku, Shikoku and Kyushu areas. Toriten is tempura-style fried chicken originally from Oita prefecture. In this sandwich it's topped with a a spicy cod roe sauce.
