​An infamous deep-fried burger filled with melted cheese is being released by McDonalds tomorrow - but only in Japan.

The fast food chain is marking 45 years of business in the Asian country by re-releasing its calorific Cheese Katsu Burger.

It features a breaded pork fillet filled with cheese, which oozes out as you bite into it.

There is also a garnish of cabbage to cut through the richness, along with a dollop of mayonnaise.

The burger was first released in 1991 and is being brought back from Wednesday for one month only, and will cost the equivalent of about £3.

The burger is somewhat of a cult hit, with many fondly remembering the fatty treat despite it being released 25 years ago.

A short 15-second advert shows one man throwing his head back in ecstasy as he tucks into the burger, which glistens with fat as it's fished from a vat of oil.

Katsu roughly translates as cutlet and katsu curry usually sees a breaded pork or chicken fillet deep fried, sliced, then covered in a curry sauce.

The Katsu burger is a little unusual, but it shouldn't shock regular golden arches customers in Japan.

Asian outposts of the chain are known to be particularly experimental with their burgers, and the launch is likely to overlap with the sale of bacon and potato pies in the country.

It's the same crispy bubbly pastry seen on apple pies here in the UK, but filled with bacon and potato in a creamy sauce.
