Oyster Bar & Restaurant Marin

Oyster Bar and Restaurant Marin sits on Miyajima Island's main shopping street (Omotesando), a short walk from the ferry pier and the iconic torii gate of Itsukushima Shrine. Miyajima is the spiritual home of Hiroshima oyster culture — the island's waters form part of the Seto Inland Sea farming zone that produces Japan's largest oyster harvest — and eating freshly grilled oysters on the island is one of the quintessential Hiroshima Prefecture food experiences. Marin capitalises on its island location by serving the freshest possible kaki alongside a short menu of anago (sea eel) dishes, which is the island's other signature food. The open-air grilling stations along the shopping street emit the smell of oysters over charcoal throughout the day, serving as a natural draw for passing visitors. Grilled oysters with a squeeze of lemon are the main event, cooked right in front of visitors on small portable grills — the shells pop open as they cook and are served immediately. Anago-meshi (sea eel rice) sets are also available and pair well as a second course. The restaurant operates from mid-morning until early evening, with supply often exhausted by 4 PM on busy days. The casual setting, sea-adjacent atmosphere, and post-shrine walk timing make it an excellent late-morning or early-afternoon stop. No reservations are needed or possible; walk-in only.
