Hiroshima is famous for oyster cultivation. Take a trip to Miyajima and be amazed at the wide array of big fresh juicy oysters. Hiroshima Bay is bestowed with calm seas with moderate tidal movement, which are conducive for the setting up of cultivation rafts. Plus, mountain waters bring a wealth of nutrients into the seas around Hiroshima, stimulating the growth of plankton. Plankton is the staple diet of oysters. With such superior conditions, it’s no wonder that Hiroshima is the perfect breeding ground for oysters.
