February is Oyster Month in Hiroshima
In case anyone is thinking about being in HIroshima prefecture from late January into March, it's oyster festival season. Every weekend features some kind of oyster festival in some part of the prefecture. I'll try to go to a few but most izakayas and many restaurants around here have some sort of oyster preparation on their menus, so there's no shortage of getting and enjoying local oysters.
Although the linked calendar is from 2011, they all follow the same schedule for this year as well.
