A festival featuring Japanese-style hotpot, commonly known as sukiyaki nabe, has attracted food lovers and tourists in Tokyo.

The event was held at a park in central Tokyo, with hotpot restaurants serving up their best dishes.

At the hotpot festival, each meal costs about 5.5 to 11 U.S. dollars, and popular restaurants can sell up to 2,000 portions a day.

However, due to the recent rise in the prices of ingredients such as seafood and beef, the price of hotpot has also increased.

Japanese residents have been agonizing with the surging food prices. So far, as much as 70 percent the country's large restaurant chains have raised their prices this year, with about 20 percent having raised prices at least twice. Japanese families have to pay an additional 70,000 yen, or about 500 U.S. dollars for one year's food.
