McDonald’s is huge in Japan, and it just got bigger with its Mega Potato Fries.

IT Media reports (via Kotaku) that McDonald’s is now offering its largest calorie item in the history of the chain with the Mega Potato. It holds the equivalent of two large fries, but at almost half the price.

Unfortunately for you McDonald’s french fry fans, the Mega Potato is only available in Japan. You could hop on a plane to grab some, but you have to be fast. The Mega Potato will only be on sale through the end of June. After that, you’ll have to start forking over $6 for two large fries.

This isn’t the first time that a fast food restaurant in Japan has offered ridiculously sized meals. For the release of Windows 7, Microsoft teamed up with Burger King to offer a seven-patty whopper. Earlier this year, Japanese restaurant chain Lotteria outdid everybody with a nine-patty cheeseburger to coincide with the release of Evangelion 3.33.
