Japanese snack enthusiasts claimed today to have set the record for the world's largest-ever rice cracker.

With a diameter of 160cm the cracker dwarfs the typical "senbei", a crunchy snack made from rice flour that is eaten widely in Japan.

For Michihiro Yamaguchi, a 63-year-old member of The World's Largest Rice Cracker Committee in Kioroshi, a town east of Tokyo, it was a moment of triumph.

"We made it. It's sweet revenge," he said, after a failed attempt to get into the record books last month with a cracker that fell three centimetres short of their target.

The group started making dough with 15kg of powdered rice yesterday and baked it for about an hour today over an open fire, turning the giant snack every few minutes.

Once the cracker was measured and photos taken to prove their feat for an inaugural Guinness World Record largest rice cracker title, the soy-sauce flavoured snack was broken into small pieces and presented to townsfolk.

"I hope that people all over the world will hear about our town because of this," said Yamaguchi.
