The Japan Sake and Shochu Makers Association lists no shochu maker in Saitama. That is the ordinary case north of Kyushu, and it is the reason every prefecture is drawn on the map at its real size: shochu is a southern drink, and most of the country makes sake instead.
Blank here means nobody is listed rather than nobody being there. A small producer outside the association, or a sake brewery distilling its own lees for the local market, would not appear in that directory and would still be real.

A producer is linked only where a page on their own domain was read while researching one of their bottles. The rest have no link rather than a guessed one.
