Burger King Japan's "Dirty The One Pounder" Lands Aug 7 — 4 Patties, 527g, and You Can't Get It Anywhere Else

Burger King Japan's semi-regular monument to excess — the One Pounder series — is back with its third 2026 installment: the "Dirty The One Pounder," launching August 7 for a limited time in limited quantities.

Four flame-grilled 100% beef patties. Four slices of cheddar. Total weight: 527g. Total damage: 1,656 kcal. The numbers alone are intimidating, but relax — the only thing getting dirty is your hands. With garlic.

And here's the kicker: the One Pounder is a Burger King Japan exclusive. It doesn't exist in the US or anywhere else — it's the burger that makes overseas food media go "Burger King Japan has lost its mind (complimentary)" every single time. You want this monster? You come to Japan.

The Sauce Is the Star: Special Garlic Mayo, Everywhere

This round's headliner is a special garlic mayo sauce loaded with both garlic paste and garlic powder, finished with a punch of black pepper. It melts into the juices of four flame-grilled patties for an eating experience that fully earns the name "Dirty."

There are pickles and onions in there too, so technically you're having vegetables. Technically.

Price: 2,490 yen solo / 2,790 yen as a set (tax incl.)

Half-Cut Service and a First-Come Sticker

For the sensible people saying "there's no way I finish this alone" — ask at the register and they'll cut it in half. Sharing is the smart play.

Buyers also get an original sticker, first come, first served, while supplies last.

Part 3 of the "Dirty" Saga

2026 has already given us the "Double Beef & Hash Big Mouth Dirty" and the "Beef & Chicken Big Mouth Dirty." This One Pounder is the finale — the official press release literally calls it the pinnacle of Dirty.

The Details

Launch: August 7, 2026 — limited time, limited quantity
Where: Burger King locations across Japan (except Tokyo Racecourse, Kyoto Racecourse, and Kansai International Airport)
Note: Stores with morning service start selling it from 10:30 AM

RAW JAPAN's Takeaway

527g is roughly five convenience store rice balls in burger form. Attempt it solo at lunch and your afternoon productivity drops to zero. The half-cut share strategy is the wise choice — but fair warning, the garlic hits at full power even at half size, so maybe don't schedule any face-to-face meetings afterward.
