Those looking for a little more weight to their burger order in Japan haven't had to stray far from Burger King lately. With regular heavy duty releases such as their Tokyo Teriyaki Tower, all-you-can-eat One Pound Beef burger challenge, and Ugly Burger series, there's plenty of options for big eaters.

So why not add a couple more? Burger King Japan is doing just that with a new limited-edition release of a duo called Big Mouth Burgers.

The two Big Mouth Burgers each feature three flame-grilled 100% beef patties, and will be available as two extra large burgers that blend cheese and spice.

The first is the Cheese & Cheese Big Mouth Burger, which along with the three beef patties, is topped with creamy jalapeno cheese sauce, rich cheddar cheese slices, and shredded cheese made from a blend of three types of cheese.

Those hoping for a little more kick can turn to the Super Spicy Big Mouth Burger, which tops the trio of patties with a mix of a special spicy jalapeno sauce and jalapeno cheese sauce.

Both Big Mouth Burgers will be available at Burger King locations throughout Japan from August 27th to September 9th, priced at 1,080 yen a la carte and 1,380 yen in a set.
