8 & 9 February, 10am to 3pm
Oyster fans, put this in your planner. Miyajima Island in the Seto Inland Sea is renowned for its oyster farms, and February is typically peak season for the mollusc.
The festival is dedicated to this abundance, with freshly shucked oysters, oysters sizzling on the grill, crispy oyster okonomiyaki pancakes, oyster stew and more. Free entry (dishes cost from 100 to 200 yen each).
