The Japan Sake and Shochu Makers Association lists 1 shochu maker in Shimane working from sweet potato. It is a sake brewery that also distils, which is what shochu usually is outside Kyushu: a second product rather than the house's reason for existing.
They are named below because a directory of who makes what is worth publishing whether or not we hold any of it. A bottle gets a page here once somebody has published enough about it to write one that is not guesswork, and for most of these that has not happened yet.
Who distils here
The Japan Sake and Shochu Makers Association lists these as distilling here. We hold no bottle from any of them, so there is nothing to recommend and no tasting note to give. What follows is a record that they exist, with their own site where the association publishes one.
