This is a google map based on the map provided to me by the Yamaguchi Tax Authority. I make no guarantees as to its accuracy, and PLEASE do not use this to just drop in on a sake brewery. Many of them are not ready to accept tourists. Check their websites or call in advance.
The blue “bullseye” icons represent working brewers.
The “circled square” icons are dormant breweries that are still selling their own labels of sake, but made by someone else.
The red exes are breweries for which I can find no current activity.
