Story highlights Burger King says you get a free Whopper when you buy Flame-Grilled Fragrance for about $41

Burger King did this a few years ago in U.S. with the fragrance Flame

(CNN) Is it an April Fool's gag or flame-grilled brilliance? We'll have to wait until April 1 to find out.

Burger King ads in Japan promise a limited-edition perfume for April Fool's Day to make you smell like a couple of all-beef patties.

The name may lose something in translation, but Flame-Grilled Fragrance will sell for 5,000 yen (about $41) and comes with a free Whopper. How's that for an offer?

It's a one-day sale, according to Burger King, and only available at stores in Japan. Sorry, rest of the world.
