These figures count the winery listings on this site. Every listing carries its own sources and verification date. Anything we could not verify is left out of the count, so the real numbers may be higher. A founding year may refer to the parent company — often a sake brewery — rather than the year winemaking began.

Shiga's official prefectural site introduces Hitomi Winery in Higashiomi City as a producer specialising in unfiltered "nigori" wine made entirely from fresh Japanese-grown grapes. The prefecture's official tourism site describes a winery in Ritto City that grows its fruit on estate vineyards cleared from rough ground, farmed organically without herbicides.

Climate

The prefecture's official tourism site describes the vineyards in Ritto City as enjoying strong sunshine and a sharp difference between day and night temperatures.

Soil

According to the prefecture's official tourism site, the Ritto vineyards were created by clearing large stretches of rough land and carrying out a major "tenchi-gaeshi" operation — swapping the topsoil with the subsoil beneath it. This describes deliberate soil preparation carried out to build the vineyard, rather than the natural make-up of the ground.
