September 28th. Burger King marks its fifth anniversary back in Japan with an "irrationality" themed burger - because hamburgers with black buns ARE CRAZY.

The buns are made with bamboo charcoal and the burger is slathered in "black ketchup", which is made from squid ink and garlic.

Price at ¥480 (6 bucks or so), the Premium Kuro Burger will be available for a limited time only.
