What Are Oarai’s Popular Oyster Shacks?

Oyster shacks are casual seafood spots where fresh oysters and other shellfish can be grilled and enjoyed on-site. One place closely associated with the origin of this dining style is Tara Town in Saga Prefecture, which is known as the birthplace of the oyster shack. The story is said to have begun at a local shop called Sono, where oysters were grilled over halved oil drums so customers could sample them. As more people came to eat, the shop gradually added more seating and grills, developing into the oyster shack style that later spread to other parts of Japan.

Some Oyster Shacks Offer All-You-Can-Eat Options

If a trip to Oarai means enjoying as many oysters as your heart desires, an all-you-can-eat course is a great option. Prices and time limits vary by restaurant, so be sure to check the details in advance and choose a place that fits your budget. For oyster lovers, it is a great way to enjoy plenty of fresh, rich oysters. Make the most of the allotted time and enjoy as many as you like.

How Oyster Shacks Work

At oyster shacks, choose from seafood such as oysters, scallops, and clams, then enjoy them steamed in a pot or grilled over a wire rack. Many all-you-can-eat courses also come with side dishes such as fried oysters. Some places offer both grilled and steamed oysters, while others allow oysters to be ordered individually. Depending on the restaurant, guests either grill the seafood themselves or have the staff cook it for them.

Best Season for Oyster Shacks in Oarai
