This annual event is held in the fishing town of Hiroo, where you can enjoy a wide variety of fresh seafood and mountain produce from Hiroo. The main event is a demonstration and sale of hairy crabs boiled in a large cauldron. It is extremely popular every year, with many people coming from far and wide to attend, even if they have to queue up. Crab soup, made in a 1-meter large cauldron, is also very popular.

In addition, there is a wide variety of seafood available, including shishamo (smelt), salmon roe, and whelk, and the market is bustling with people enjoying the taste on the spot and taking some home.
