Ginza is a name found in various locations, not just Tokyo, and you'll find one in Akashi as well.
While it can't compare to the bustling Tokyo Ginza, it has a variety of shops and is connected to Uonotana, Akashi's kitchen, making it a lively spot.
It's located at an intersection with National Route 2, so there's plenty of traffic, but you'll often see people taking a quick break there.
